The Baxter Steam Street Car.

When the horses iu New York were all down with the distemper the Common Council passed a resolu¬ tion allowing the use of dummies, and one, the Rem¬ ington Steam Car, was tried on the Bleecker street road. It worked well, and its triumph was all the greater from the fact that the road over which it ran is exceedingly tortuous and has some heavy grades. This car with its machinery is illustrated in the ac¬ companying engravings. It is the invention of Mr. BaxTEB, already known by his admirable portable engine and by the

somewhat more coal that the above estimate, but the saving in running expenses would still be marked.

The engine is placed in the front door of the car, and the driver stands on the front platform. These engines, from their peculiar power of ascending heavy grades, would be of great service as mining locomotives, and would often save embankment and tradk-laying in quarries, iron*mines, etc.

The boiler is up¬

Ig, it has two cylin¬

ders connected by a

steam chest. The large cylinder ex¬

hausts into this steim

chest and thence into

the small cylinder which works at half

the pressure of the large one. Wnen it

is desired to run up a heavy grade, the in¬ termediate steam chest can be connec-

The allowance for horses is 4i pairs to one car, and it costs $1 25 a day to maintain each team, or $5 62 in alL The increase of weight from over-loading, which

Barrel Amalgamation in England.

Atteb'bo many improvements in the modes of treating silver ores containing oopper, lead, iron,

sulphur, etc., it is a little surprising that the old Freiberg barrel amalgamatio}! has been lately intro¬

In domaetic economy we fled tbe dolomite, pixyf an impoittnt part in the Uoited 6utm. It forme a naefol material in arebiteetnre. Tha new cathe¬ dral of New York is built of dolomite from our imme¬ diate ncighitorbood, in WestebsHter Connty. The white marble of 'Vermont, which has supplied tbia city for many years wilb tbe material for tbonaanda of palaoea, ia dolomite. If dolomite conUina the additional ingredient, clay, it ia converted into a water cement, like that of Bondont. It is tbe meet common limeetone, not alone in tbia State, bat all over the United Sutes. Tbe lead-bearing rocks, par- tionlarly those of Wiaoonain and Illinois, which are of the Potsdam period or lower ailnrian, are dolo- mitio limeatone, while those of lliaaoori and ArHhn- saa are also tbe magneaian 1‘mestone of the Calcifer-* ons epoch. Tbe same lime is the material in tbe manntactnre of tbe Olen’a Falls and Thomsstown morUr lime, for building pnrposes—tbe former from New York and tbe i.'itter from Maine, The Boaendale

oement owes ita powerful bydranlio qualities to tbe amonnt of 20 per cent, clay it conUina. Tbe mi je- ral from Hintings-oD-tbe-Hadnon does not contain any clay, bat is used aa building material, or is burnt and Sold as canatio lime.

Tbe pearl-spar of L'jckport is a oryatalline dolo¬ mite, of rhombohedial form, and does not contain aiiicate of alnmina.

' Mineral >gioal'y, dolomite comprises a vari-ty of minerals, of different forma, anoh as the bitter or brown spar, gnrbofiao, miemite, ankerite, and aome

species, formed by replao ment of the lime with a protozida of iron or manganeae. Tbe bydranlicity and oonoretion of the eomihoa lime and dolomite are very imporUut. Tne strength and bardneaa of mortar reenlt from the cobesiveuesa of sand and Carbonate of lime, is obtained from tbe contact of quicklime and water, whioh at first forms tbe

hydrate of lime, and, by anbseqaent absorption of oarbouio acid from the atmoaf hsre displacing tbe W8te>r produces tbe carbonata of lime, which grasps and binds the grains of sand.

The bydranlioity of dolomite depends upon a cer¬ tain percentage of clay, for nnless the native mineral contains at least from 10 to 15 per cent of clay, it will not form a water cement. •

By tbe CHlw’ination jt a dolomite^ containing at least that qnsnti'y of clay, we obuin a composition

posaessiog bydranlio properties, wbieh increase with the proportion of clay. Even when tbe amonnt is one-third of tbe lime, tbe miztore yields a 'mortar, which hardens almoat immediately under water. A mizture of dolomite, pozsnol me, and magnesia, or

magneaia and ealoined clay with common lime, forma a valnable water oement.

, expressed by Prof. Thobston in connection with the report of the first series of tests : that a weakening effect may be produced by the wrenching and twist¬ ing accompanying explosions. Mr. F.

Cold in Sea-Water.

Bt E. Sonstadt, in Chemical Neu>s.

I bite used three entirely different methods for

the detection of gold iu sea-water, but ail the me¬ thods were applied to the water itself, not to the re- sidne left on evaporation. The experimente have been made npon specimens collected at different times from different parts of Bamsey Bay, Isle of Mao, and the reanits obtained from the different specimens have been in entire aeoordance. The pro portion of gold contained in ses-water (oertoinij less than one grain in the ton) is mnoh too small to ad¬ mit of separation, or even detection, by the nsual

tests applied in the usual manner. Besides the dif< ficnlty of detection arising from the small proportion of gold present, there is another difficulty of E graver kind, doe to a continnons re-sointion of the gold after it has been separated in tbe metallic state. This re solution is owing to tbe separation of iodine under tbe infiuence of reducing agents npon the iodate of ealeinm, which, in a paper published in tbe Chemical yews, I have shown to exist in sea-water. Even if the reducing agent is added in very large excete, oxidation takes place so rapidly under the eontinn ous re-forming power of iodate of calcium, that, ■oonar or later, according to the exoeu of rednoing

agent used, the stage arrives at which'iodine is set

free, and tbe suspended gold is re-dissolved.

I. Tbe first method I shall describe of detecting gold in sea-water may be practised npon so small a quantity of water as 160 or20J c.o. Two or three decigrammes of pore ferrous sulphate ore dissolved in the water, which ie acidulated by two or three drops of hydrochloric acid. The solution is heated in a chemically dean and well glased porcelain dish, over a small ^me, so managed that tbe flame may tench the under part of tbe dish witbonc causing cbnllitioo.^ Under these circumstances a Instrons film of ferric oxide forms in tbe dish, commencing from the portion directly heated by tbe fl kme. Tbe heat is continued, without boiling, until Iha sea¬ water is svaporated to about half, or so ling as tbe film incresses in extent and in lustre.

Tbe l:quid ie then poured off, the strongly adhe¬ rent film is rinsed with a liitle water, and then about 50 a 0. of strong oblurinu water is allowed to stand in tbe dish for an hour or two, after which it is slowly evaporated down (over tbe film) to a few drops, a

drop of dilute hydroolorio acid being added Uiwards (be end of the evaporation. The liqnid, which should be nearly colorless, is then poured into a test glass containing a few drops of solution of stanuous chloride, when, alter a few minutes, tbe liquid takes a bluish or purplish lint, which may be exactly matched by a drop or two of .a suitably diluted solu¬ tion of gold added to a corresponding portion of tin- salt in another glass. Tbe re-action may, of oonrse, be made more striking by taking for the experimeut a larger quantity of sea-water, although tbe reaction obtainable from tbe quantity indicated is quite defiuite. I have repeated this experiment many times, upon different specimens of sea-water, and always with the same result when a film was obtained on evaporation. But tbe formation of (his film depends npon tbe iron being in a particular degree of oxida tion, and I have sometimes failed to obtain it. The beet way is, after adding tbe ferrous sulphate and bydr^blorio acid to tbe sea-water, to leave it ex

poied to tbe air for a few hours, or overnight before beating tbe liquid to obtain tbe film. .Corresponding experiments were made, in tbe same vessels and with tbe same re-agrnts, npon simple water, and upon water contaiuiug chloride of sodinm aud a’kali sul* pbates in eolation, bat tbe films obtained, when treated as described, never gave tbe slightest colora¬ tion with eolation of stannons chloride. Tbe chlorine solution of the sea-water films may be dried up in a porcelain crucible with precipitated lead, and gold beads obtained by onpellation, after fnsing tbe lead into a bniton with borax ; but for this experiment at least half a litre of sea-water sbonld be taken, and even then tbe bead obtained ie not ponderable.

IL From half a litre to a a litre of sea-water ebonld be taken for tbe experiment now to be described. As mnoh solution of pure chloride of barium is added to tbe water aa will give sbont a grain of precipitate. A day or two abould be allowed for the precipitate to settle. The precipitate is collected, dried, mixed with borax and lead, and tbe button of lead obtained before the blowpipe on charcoal is cupelled. Tbe bead obtainsd is yellowish white, of tbe same color

as sn alloy of 60 parts gold to 40 of silver, or tbere- aboute. For confirmation of tbe presence of gold, the bead may be diseolved, in a very small test-tube, in a few drops of aqua regia, which is then evapora¬ ted, at a gentle heat, nearly to dryness. A few drops of pore bydrochlorie soid are added, and the solution again evaporated, to destroy the excess of nitric acid. Tbe solution is evaporated very nearly, but not quite, to dryness, a few drops of water are added, aud the mixture warmed, and when the chloride of silver is settled a drop of eolntion of stannous chlo¬ ride is allowed to fall down the side of the tube into the liquid, when the ebaracterietio gold reaction is obtained. This experiment ie delicate, end requires some ears. For the laboratory method I. is much the easier end quicker of the two ; but it is concsi-

vable that vethod IL might be practically applied to

the exploitation of the geld in eea-water, which might be received at high water in litrge tanks, and emptied at low water, tbe chloride of barium eolntion being meanwhile need, and the precipitate left in the tank taken out from time to time.*

CONTINUED nou PlOE 376.. XXVIII. Tbe loss of heat occasioned by cooling

tbe tnyeres with water does not seem to be eepeoiallj worthy of notice, to judge from tbe experiments made and mentioned in what has precededi at least so long as the number and eixe of the tuyeres are not greater than commonly met with in Sweden. This loss of heat must, however, necessarily increase in propoit'on as tbe tnyeres project more and more from the burning away of the Lehrtb. In any ease it does not seem advisable to oonduot so mnoh water through the tuyeres, that ou esoaping it should be entirely cold, siucu a more considerable uooling of tbe tnyeres than is necessary to preserve them, always occasions an unnecessary, even though not consider¬ able, obilling of the health, and frequently, also, tbe formilion of a nose (i. e., slag prolongation of the tuyeres.)

In blast-furnaoes of varions countries, where the attempt has been mad-t to use as many tiyeree as possible, the loss of heat occasioned by Water tuyetes must be consideiable. Thns, for example, at the Thomas Iron Vfoiks, in Pennsylvania, it was found necessary for this reason to diminish tbe number of tuyeres t om twenty-three, tbe number set previous to bluwing-io, to eleven.

XXIX. With regard to tbe loss of beat ooossioned by tbe tyrop and fore-hearth, it is evident tact it must be less, tbe smaller tbe exterior of tbe parts mentioned is and the less s coding is prodooed by tbe wearing of tbe fore-hearth. Tbe most radical move made in this direction is that of arranging tbe furnaoee with a closed breast, as is costomsry in Styria, where there are no other openings than a tap¬ ping-bole at tbe bottom for tbe pig-iron, and a seoood tap a few inobee below tbe level of tbe tnyeres for tbe ciuder. In order to prevent tbe eind*r-tap from being too readily alticked by tbe 1 quid cinder, and, consequently, being too much enlarged, it is oon- etrncted of iron, and, like the water-toyerec, pro¬ vided with an annular opening, tbrongh which water fiows for tbe pnrpoae of cooling. These so-ealled LUbmann’s cinder-taps have recently been‘extensively introduced, eapecially ini Germanyf, and it ie asserted, with respect to them, that they diminish the oooling of the hearth, at well as produos a shorter intermption in tbe working of tbe fomaoe wbca casting tbe iron ; so that considerable advantages are cliimed for them.

This view has much in its favor, and is greatly supported by the fact that if oxalic add is added to sea-water some time before the addition of chloride of barium, it ie scarcely possible to detect gold in tbe predpiute ionned. AndTtbis is easily to be understood, since oxalic acid reduces sll gold salU; and in so dilate a liquid-tbat is, a liquid in which any gold reduced is so finely divlded-sny predpitation of such gold, nnlese under the oonoitions d«racribed to tbe methods I. and III., could not be expected to take place.

Besides whioh this loss of heat most seif eridently, depend on the diffjrenoe of tem- peratore existing between the interior 'and exterior of the fnrnaee, and is, tberelore, somewhat greater in winter than in snmmer. But in the same season, and when making a tiniform quality of iron, this dif¬ ference in tumperatore, in the same fornaoei can scarcely rary to sooh a degree that the amount of heat lost in this manner can be perceptibly changed. Tbs loss of beat thus produced most, therefore, in j one and the same furnace, really depend on the time and tbe weight of the charcoal charged or pig iron prodoced. Conseqaently, it will become rela¬ tively smaller as the nomber ot charges or the pro- dooiion is increased within a given unit of time.

XXXI. It has already been shown io what has pre¬ ceded, that by increasing tbe nomber of charges, the warming in the opper portions of the furnace of tbe materials to be smelted is diminished, and if it also be borne in mind that the loss of heat by radia¬ tion from the walls of tbe furnace, is much less, per weight-unit of pig iron, prodnoed by increasing tbe number of charges, then, it becomes very evi¬ dent, that the changes in tbe nomber of cbarg. s, afford tbe most available means to effect an unequal distribution of beat in the interior of the blast-ior- nace. Since by increasing the number of charges the beat can be concentrated ss much as possible in tbe lower portions of tbe furnace, while by dscreai- ing tbe rapidity with which the furnace is charged, a more uniform distribution of tbe same throngh tbe fur Dace in an upward direction can be obtained.

XXXIL If it be assumed that the air contains as much water as it is possible for it to absorb at -f- 5*C., the amount of heat conducted into tbe furnace, ob¬ tained by beating the blast, is per weight unit of

blast forced into the furnace: 7640X0-2^X0-0056X0 475=0 240 oal„ lor each de¬

gree centigrade which tbe blast brought with it into the furnace. Tbe aiuount of heat thus carried into the furnace, which with a temperature of blast of, for exam pie, 203*C., (according to the preceding calonla- tions with regard to beat,) amounts per weight-unit of fuel charged to 184 2 cal., or 12.6 p. c. of the total quantity of heat conducted to the furnace, (1796 3 cal.,) does not, however, appear to correspond to the saving in coal attained in practice, which latter, by tbe jise of heated blast, is generally much greater.

Most metallnrgicsl writers, as Tumnxb, Pxbot, WxDDDio, etc., have attempted to explain this im¬ portant phenomenon by the more active combus¬ tion which is produced by heating the blait. The total quantity of heat in the furnace cannot, however, be increased by such a lively combustion. Since even if it be assumed that the hot blast in the focus of combustion renders this last more perfect, and produces more carbunic acid than is tbe case by tbe combustion with cold blast, still no actual saving of heat is attained, since it wonld then happen that the carbonic acid thus produced would not again be re¬ duced by tbe white hot coals to carbonic oxyd. This reduction appears, however, always to occur, sinco the analyses of blast furnace gases hitherto made, show, that in the case of hot as well as cold blast, the carbonic acid first formed in the focus of combus¬ tion, is immediately reduced to carbonic oxyd on coming in contact with the white hot coals wilboct

* With regard to some experiments made with furnaces having very t>iin walls, the reader is referred to this jour¬ nal, pp. 2M and 807, and Esoineehino, vol. xiv., pp. 208 and 2sl; also Berg und HiiiUnmannUche Zeitung, 1870, p. 436, with drawing of the furnaoe.—F. P.

tbe focus. Therefore, tbe production of beat will, on the whole, be no greater in tbe one case than in tbe other, or as if tbe whole of the oxygen contained in tbe blast had from tbe beginning been used for tbe production of carbonic oxyd only. Tbe influence of tbe more active combustion prodnoed by tbe heated blast, must be confined, therefore, to a nar- nower limitation of tbe focus, within which the heat

is more concentrated. Within tbe focus, tbe gases are well known to be

oxydixing in their action, and tbe limitation of the actual space of combustion, can therefore be of use beyond oavil, especially when employing a high pressure of blast. This limitation can be advan-

tageons’more especially in tbe case of coke, since tbe reduction of tbe carbonic acid, formed by this dense fuel, does not take place with tbe same ease or so rapidly, as in tbe case of eharcoal; although with an increased temperature, tbe reducing power of tbe coke must also increase. We moat also look to this

difference as tbe reason why the use oi the hot blast has been of greater advantage in coke blast fur¬ naces than in charcoal ones. Besides, tbe limitation of tbe space of combustion in blast furnaces using charcoal, can also be of some advantage, and in any case, tbe hot blast has the advantage of keeping the month of tbe tuyere more readily.olean. But if tbe saving of coal attained by tbe hot blast, together with tbe gain of beat, which, aocoiding to tbe ordi¬ nary calcnlation, is conducted to tbe furnace, were actually to be ascribed only to tbe action obtained by confining tbe space of combustion, as appears from a cursory examination, the action wonld in fact

be unexpectedly great

A closer examination shows however, that the heat which is conducted to the blast-furnace by beating the blast, acts, compared with tbe beat produced in tbe furuace by the combustion of tbe coal, very dif¬ ferently from what has hitherto been assnmed. Since it has hitherto been overlooked, that by the combustion of the coal, a portion ot the heat thus produced (depending on tbe temperature of the tun¬ nel-head gaees) does not become available to the furuace, while on the other band the heat conducted in by tbe hot blast is, with scarcely any dednction, utilized in tbe furnace. Not a cubic inch more ot gas is prodoced in the blast-furnace by the beat in¬ troduced into tbe furnace by tbe hot-blafct, than would be tbe case if ice-cold blast were used to con¬ sume tbe same quantity of coal. If, therefore, tbe ex¬ cess of heat remaining in tbe furnace should be pro¬ perly utilized, tbe tuunel-gases withdrawn from tbe furuace do not need to carry off any more beat tbau would be tbe case with cold blast. Tbe rase is en¬ tirely different, if the beat carried into tbe furnace by the hot blast must be replaced by an increased charge of coal, or what is tbe same thing, by tbe combustion oi more coal. Since this cannot take place without in¬ creasing tbe quantity of gas, which increase is una¬ voidable from the augmented amount of coal burnt and qnantity of air necessary to its combustion ; and in proportion as these increased products of combus¬ tion pass off from the furnace in a hotter condition, so must tbe portion of beat remaining in tbe furnace, prodnoed from this augmentation of tbe coal, become

less.

In order to illustrate better this comportment, we will examine how great this saving of fuel is, whioh is produced by the use of tbe hot blast in a furnace working under the conditions assumed in tbe beat calculations made in YIL, and the following para¬ graphs.

As tbe charcoal consists of 82 per cent carbon, 2 per cent, asb, 10 per cent water, and 6 per cent, ga¬ ses expellable at high temperatures (wbiob last cou- sist OI 55 9 per cent, caibonio acid, 22.8 per cent, carbonic oxyd, 11.8 per cent, marsh gas, 1 per cent hydrogen, aud 8 5 per cent nitrogen), there is ue- uessary to burn the carbon present in one pound of tbe charcoal to carbonic oxyd, 1.0933 pound oxygen, whioh is contained in 4.6444 pounds air. This amount of air contains in addition to the oxygen

3.5483 pounds nitrogen, and in the assumed quan¬ tity of gasified water there are 0.0028 pound hydro¬ gen. Tbe gas mixture, formed by tbe combustion of one pound of charcoal with air to carbonic oxyd, consists therefore of:

0.06X0 559.=s0.0335 lb. carbonic acid, 0 06X0 228-1-0.82X28-^12=1.9270 » carbonic oxyd, 0.06X0.118.=0.0071 “ marsh gas, 0.06X0,01-1-0 0028.=0 0034 “ hydrogen, 0.06X0-085-j-3.5483.=3.5634 “ nitrogen, and

0.1000 "aqueousvapor. The beat produced by this combustion amounts,

per weight-unit of the charcoal, to: 0.82X2473— 0.0028X29638=1944.87 cal. To vaporize tbe water contaiued in tbe charcoal 63.1 cal. are necessary, and the beat conducted off by the tunnel-head gases

amounts to :(0 0336-H) 2164+1.9270X0.2479-fO. 0071 aO. 5920-H). 0034X3.4046+3.6534X0-144) 460+0. IX 0.476X350*=1.368X460+16.6=632.2 calorics. The qnantity of heat carried off from tbe fnrnaee for each pound additional of the charcoal thus consumed

amounts therefore to 63.1+632.2=695.3 cal. And the beating power in qaestion thus utilized in tbe

furnace amounts to 1945.3—695.3=1250 cal., or to 64.26 per cent of the qnantity of beat prodoced by tbe combuHiion of 1 pound extra of charcoal added.

It has already been shown in the preceding that the qnantity of heat which is carried to a furnace working under the conditions aaaumed, with a tem¬ perature of blast of 205** C. amounts to 10.2 p. o. of all tbe beat which falls to the lot of tbe furnace. If we consider, in addition to toe just mentioned re¬ lation, that only 64.26 p. c. of tbe heat produced by tbe cojabustion ol tbe extra coal in tbe furnace is utilized, it becomes evident that the saving of fuel attained by tbe hot blest is not confined to this 10.2 p. c. ; but, leaving out of corsideratiou tbe advan- Uges possibly attained by a more active combustion, that it amounts to 10.2+0.6426=15 87 p. c. of tbe amount of fuel required with cold blast.

TXXIII. From what baa been stated tbe reason at once becomes clear why the saving of fuel obtaioed tbrougb the hot blast varies so much in lurnaces ol different dimensions and working under otherwise different conditions. S<uce in proportion as tbe heating power of the fuel charged is more perlectly utilized within tbe lurnace, tbe saving produced by beating the blast will decrease ; aud the reverse is also true.

The smaller tbe blast-fomace is, and tbe greater distance below tbe top tbe lurnace-gases are with¬ drawn, so much tbe greater must be the saving ip fuel which can be produced by beating tbe blast; aud inversely, the larger tbe furuace, and the nearer tbe top tbe gases are taken off, so much tbe less must be tbe iufiuenoe of tbe heated blast on tbe consumption! ot coal. Could such a point be|attained that tbe temperature of tbe gases passing away from tbe blast-furnace was not higher than that of tbe exterior air, and that tbe fuel used con¬ taiued no volatile ingredients whose gasitioation con¬ sumed heat, then, indeed, heating tbe blast would be of not much greater advautage tbau that correspond¬ ing to the quantity of coal, which, by|its combustion, produces just as many calorics as are carried into tbe lurnace by tbe heated blast. But, since such a perfect utilization of tbe beatiug power of tbe luel ebargt d cannot be attained even in tbe largest lur¬ naces, tbe beating of tbe blast must always cause a saving of fuel; even in those oases where tbe blast- furuaoe gases could very well be used otherwise.

It becomes also evident from tbe preceding that the larger the quantity of volatile ingredieuUi in the fuel, especially tbe more moisture it contains, so much tue greater must be tbe effect of tbe hot blast since a considerable amount of boat is rendered lat¬ ent nud carried off by tbe gases in theâsification of these volatile ingredients, as appears proved by the precadiog calc ulat ions.

Even the moisture of the air must affect the ac¬ tion of the heated blast in such a manner that the saving ot luel with a certain temperatnre of blast must be tbe greater tbe more water ihe air contains. Tue reason for this is soon discovered if it be remem¬ bered—

lot. That tbe moisture of tbe air, for tbe reasooi mentioned in paragraph XXI., always lowers tbe temperature of tbe lurnace; hence, in proportion as tbe air contained more water, it must be tbe more advauUgeous if, in consequence ot tbe use of heated blast, less air hiui to be blown into the lurnace per weight-unit of pig iron mads ; aud

2(L Tnat tbe specific heat of steam is very con¬ siderable ; tberelore the amount ot beat of tbe blast uurrespoudiug to a certain temperature must be so much the greater the more moist ths air is.

THE COAL TRADE.

New Yobs. December 13,1872. BiuiDeai ii quiet, and eyen the cold weather of the last

few daya doea not appear to have had any marked effect npoD the demand. Pricea are however ateady, and there doea not appear to be any fear of a falL Coal ia now lower than at the aame time last year by 20 or 25 oenta a ton, and taking the circomatanoea of the year into con* aideration, the opinion ia general that the price may be eonaidered pretty well aettled. The tranaportation aeaaon haa cloaed. The canala have wound np their baaineaa, and the weather ia winding op the Hndaon River trade withont aakmg leave of dealera. To-day the ice ia faat cloning np the stream at Newburg, and the Pennsylvania company are now shippiog from Weehawken. Only a few days before moving down the river a sndden aqnall swamped 23 boats ont of a tow of 28, which was coming down by CorneJl’s line, for the company.. The waves rose so high aa to till the boats.

The nanal dnll winter in the SchnylkiU region, it ia said, will this year be transformed into a total snapension, bnt the report ia not confirmed. Considering the nanal char* aoter of the Hohnylkill trade in winter, it cannot be said that the snapension will be of any moment, and if it takes place it will be a matter merely of convenience and with ont effect upon the general market.

Bitnminona coal is in demand at good rates, bnt the high prices, of abich so much has been said for a fort* night back, do not seem to be realized. We do not know that $7 60 a ton in New York haa been obtained in any quarter, and ooal can be bad at leas than $7 26. Oaa ooals are again making their appearance in the mar ket, sinoe the Baltimore and Ohio Railroad now baa more cars to spare than before the completion of the Cumber¬ land connection with the Pennsylvania lines. The former road is therefore able to spare a few oars for gas ooal, and old contracts are now being fulfilled, though at some loss to sellers, tranaportation being $2 a ton, instead of $1 90, from Baltimore. Schooners are in great demand at that port, and there is a prospect that the rates will monnt still higher.

New projects for improving the communications north ward from the bitnminons mines are on the carpet. It is reported that the Maryland and Delaware Ship Canal Company has been fully organized, and has placed a corps of engineers in the field. The object of this enterprise is to connect the Chesapeake snd Delaware bays by a ship canal across the peninsnla of the eastern shore of Mary land and Delaware, thus shortening the distance by water communication from Baltimore to New York and the Eastern states over two hundred milei4, besides avoiding the dangers of navigaiion around Cape CbarlM. To ooal consumers this canal can be of the greatest advantage and with the immense and increasing business of ooal transportation northward from Maryland, the Canal Com pany should be able to fix its tolls at such rates make the canal a t)ecuniary blessing to the country.

Another canal undertaking of no mean importance to the Eastern states is gradually taking an definite shape namely, the Barnstable Bay canal across Cape God. would probably be impossible to find between Cape Cod and the Isthmus of Darien another spot where theontting of seven miles of canal conld so mnch shorten the travel as here. Surveys for this work have long been made, and we hope to see it quickly placed in activity.

investment in Penneylvenie.

The Irocton Journal eeyi that the project for the bnilding of e new fomeee there te now fully aseured. •• Mr. Geo. Willard la the projector, and the propoei- tioD embraeee the purchaee of Etna and Veauviaa fur- nacee, with 16,000 to 16,000 acrea of land, for $300,000, and the bnilding of a new atoneôal fur¬ nace at or near Ironton, and poeeibly the addition of other indoAtiies than the making of pig iron alone. The atock wae at flrat intended to he but $600,000. The books were opened on Friday, and $361,000 atock was taken up to Monday morning by four men. The balance was taken up that day, and so eager were takers that another hundred thousand was added and picked up by the middle of Tuesday forenoon I A million could have been obtained in a little while, and with no trouble at alt” If those disappointed " takers” are still eager to invest their money in mining operations, they can do so very easily by coming to New York. The market for ev¬ ery kind of saleable thing is in this cjty closely de¬ pendent upon the feeling in Wall street. When the money rate is high there, and bankers are pinched, merchants move cautiously. That has been the condition of aflkirs for some time past, because this is the time for moving the crops, and money has gone to the country. Nothing can be done here in mining just at this moment, and projectors are lying on their oars. It is. expected, however, that matters will improve by January, when investors will, per¬ haps, have more money to spend.

Scientific Experiments on Steam Boilers.

Recent disasters of a serious character, resulting from the explosion of steam boilers, have called re¬ newed attention to the necessity of finding some

efficient remedy for these distressing accidents so destructive to property and life. The universal em¬ ployment of steam at the present day in naval as well as commercial operations, renders this a matter of extreme interest to all, and one demanding the seri¬ ous attention of the government In December last, at the suggestion of private parties who were about to institute some experiments upon actual boilers at Bandy Hook, I appointed a board of engineers to at¬ tend and witness the result. Appended hereto li a copy of their report, which seems to indicate that much valuable information and perhaps a solution of

the difficult problem may attend a further prosecu¬ tion of the inquiry. Indeed, the information already acquired is deemed by those competent to judge, of much interest and importance. It is gratifying to know that the experiments which have led to the most reliable information hitherto possessed by the scientific world on this difficult subject, were insti¬ tuted and conducted by an American institution, (the Franklin Institution, of Philadelphia,) under the patronage of our government, over thirty years ago. Those experiments were detailed in two able reports, one made in January, 1836, on the manifes¬ tations of steam u-der various conditions, and its effects, as steam, upon a small model boiler con¬ structed for the purpose; and the other, made some months afterwards on the strength of materials em¬ ployed in the construction of steam-boilers. The former report was published in Ex. Doc. No. 162, first aession, Twenty-fourth Congress ; the latter, in Ex.

Doc. No. 18, second session, Thirtieth Congress, in¬ cluded in a special report of the Commissioner of Patents. It is to be regretted that the experiments thus auspiciously commenced had not been continued until a complete solution of the difficulties could have been obtained. No material advance seems to have been made in real knowledge on the subject since that time, and the great desideratum at the present day is a series of well directed experiments on actual bailers u:ed in navigation.

It was the employment of such boilers in the ex¬ periments made last season, at Sandy Hook, which was the means of producing the interesting results

before alluded to.^But the making,of experiments

on this scale is attended with too much expense and risk of Capital to be carried on by private enterprise.

It can only be accomplished under the patronage of

the Government, and it seems to me that any reason¬ able outlay in this direction would be amply repaid in the increased security to our naval and commer¬ cial marine. Legislative regulation of the inspec¬ tion and management of steam-boilers must neces¬ sarily be imperfect under an imperfect knowledge of the causes which lead to explosions; and reliable knowledge can never be attained by silent reflection in the study, or by verbal and theoretical discussion, but only by actual trials on real boilers, under such conditions and circumstances as the present ad¬ vanced state of engineering science and skill shall dictate. This Department has noticed with much interest that the subject has engaged the attention of Congress, and that a law has passed one House at its late session, providing for a continuation of experiments such as have been recommended. There are few things at this time, affecting the com¬ mercial and naval interests of the country, of more practical importance than this, and it is to be hoped that the pressure of business at the coming session will not cause the matter to be overlooked.—JUport of the Secretary qf War, 1872.

Copper from Pennsylvania Ores.

The Pboenixville (Pa,) Messenger, in giving an ac¬ count of a visit to the copper works in that town, says that the old process in use by their predecessors —that of extracting the copper from the low grade ores by precipitation—bos for the present been aban¬ doned, but will be resumed at no distant day. At present the works are turning out copper by the Swansea process. The copper is made exclusively from Pennsylvania cres, taken from Jones’ mines, on the Wilmington and Beading Bailroiu], from Corn¬ wall iron ore mines, Lebanon County, and from a mine near Fottstown, Montgomery County. The first cast was made on Monday last, which was the first time that copper has been made in marketable quantities from Pennsylvania ores.

The ore averages 9 per cent, copper, and the first matte contains 30-40 per cent Tnis is smelted to white metal, and that to blue metal of about 70 per cent Then a regulns, pig metal and refined copper, are successively made. The regular montLly yield at present will be from 12,000 to 15,000 pounds ingot copper. It is the jntention of the proprietors to erect another ore furnace next spring, which will en¬ able them to double the present product

Engineering and Mechanical Notes.

Colonel J. B. Eans, Engineer of the Bt Louis Bridge, writes to the Journal of the Franklin Institute that he was mistaken in reporting that candles bum more rapidly in compressed than in ordinary air. One of his assistants, whom he had directed tb as¬ certain the rate of burning, compared the candles in the open air shaft, where they were in quiet air, with those which the workmen carried about in the cham¬ ber. The latter wasted rapidly, as miner’s candles always do when moved rapidly about the droppings and smoke which result from careless handling amounting sometimes to as much M the wick con¬ sumes. The truth is that candles bum less rapidly in compressed than in ordinary air.

The Cleveland Lake tunnel, which was 4000 feet

from the shore in April 1871, was then interrupted by the breaking in of water. Work wm then oommenoed from the crib in the lake where, after four months, soft clay was met with, and a hydraulic shield and press had to be provided. In April 1872 work was again resumed, the soft clay passed and progress is now at the rate of about 70 feet a week. The work done is 400J feet from the shore and 950 feet from the crib ; aboui 1650 remains to be cut through. These details are furnished to the Journal of the Franklin Institute by Mr. Joseph McDohxll.

The Secretary of War says in his annual report that

a comparison of the tri-daily foreoastM of the Signal Bervice Office or '* probabilities,” as they have been styled, with the meteoric condition afterward reported

so far as known, has given an average of 69 per cent, as verified up to November 1,1871. Since that date, to the present time (October 1, 1872), the average of verifications has been 76 8-10 per cent A better proof of the efficiency with which this work has been carried on Is the fact that since its inaugur¬ ation no great and continuous storm has traversed the territory of the United States, or raged along the length of its lakes, its gulf or sea-coast shores, as in their course such storms have sometimes done, with¬ out fair and general premonition given at the great

majority of the points endangered to any who cared to seek or heed them.

The great attraction nbw at the Paris Jardin des Plantes is the fossil man discovered at Monton in March last. The skeleton, which is in a recumbent posture, is half petrified, und to its head and feet adhere a quantity of small sea shells.

One of the man engines used in the mines of Pri¬ bram, Bohemia, reaches a depth of 400 fathoms, and 30(X) men go up and down it daily, in about 9 hours (3 hours for each shift) ; it makes 4 to 5 strokes of 10 ft. each per minute, requires 6.2 to 6.9 lb. of coal per hour, and per effective horse power, and costs from 24 to 30 cents per horse power in 24 hours. The engine is indireot-soting, and the rotary motion

is changed to an up and down one by means of two pump crosses.

An instrument has been invented in Germany for testing color-blindness. It consists of a rotating ap¬ paratus, which moves a disk whose center is a circle, one half black and the other white ; outside of this is a ring half red and half green, then another ring of violet and red, then the outside ring of violet and green. When rapidly rotated, the centre appears to be colored grey, that is black and white mixed. To a Treen-blind person the middle ring will appear grey, that being the result to him of a mixture of violet and red. The outer ring will appear grey to the red- blind patient, and the inner grey to the vioief blind. By the use of this instrument, a large number of patients may be simultaneously examined for one or more kinds of color-blindness.

It is said that some 6000 or 7000 lbs. of Australian gold, known as “ brittle,” having recently been coined by the French Mint for the Bank of France, all the pieces have been found to admit of being easily broken, and they have therefore to be remelted. This is attributed to the presence of a small per¬ centage of antimony and arsenic, extremely difficult of removal ; and these elements are known to pro¬ duce a timilar effect in all metals or alloys which are subjected to the molecular changes induced by the pressure and heat developed under the action of the dies in the coining press.

Barron’s process for the manufacture of steel tools —or rather, for the conversion of iron tools into steel —is now in successful operation in Louisville, Ey., where it has attracted no little attention, and has met with very encouraging success. This process, as our

readers know, consists in transforming objects of cast iron into steel, by treating them in cementing boxes

with iron oxides, as malleable castings are made, and

then subjecting them to cementation, in which car¬ bonaceous vapors are employed.

Soio of our chemical readers mty be disposed to try the following recipe for a manure for bouse plwts, proposed by Dr. Jaanm,: Nitrate of ammo-

nia, 400 parte ; biphosphate of ammonia. 200 ; nitrate of petessa, 260 ; ohloride of ammonium, 60 ; sal. phate of lime, 60 ; sulphate of iron, 40. These in. gredients are pulverised, well mixed, and kept in well-closed, dry bottles. Four grms. of this mixture are dissolved in one litre of water, and to each j lant (in pots or in open ground) is given weekly a dcee of

j from 25 to 60, ox even, in some cases, 100 grms. It

is best to pour tike liiôid into thesancers in which the ' pots are placed.
