Preface
This study was undertaken as part of a larger project of the
Agricultural Economics Division of the University of 1.iinnesota, v.hiah
embraces the subject of Dockage in its various phases . It was desired
to find the cost of removi ng dOokage , the information t o be used in
ascerta ining the value of d ockage . _ terminal gL"ain elevator vas chosen
as the base which should be used in determining costs of obtaining dookage
and in order to get this figure it was necessary to prepare a complete
cost accounting system foa a typical terminal elevator .
It was discove'.1.4ed early that no work on this subject had evel' been
done . Grain offices do not use cost finding methods and it was sornetimes
difficult to convince them that sooh methcx:ls could be a.ppliei to their
business . 'l"h e :rrethod of finding inf or mat i on was to get it thru pers an.al
interviews , and these ere had with elsvator superintendents, ain :rre
n.nd boOkkeepers . No opposition was encountered , rather an open-mimed
co-operative attitude . 'i'OO opinions of the men interviewed were o ombined
into a composite result which appears in the following i:nges . The stuey lns
centered around one s:i;ecific house , and the effect of this is to make the
results more consistent as being based on one particular case. ~e methcd a
can be applied , with slight changes in distribution, to :my house 1hich it
is desired to study.

Chapter I. Introduction
l. The purpose of this stW.y is to devise a. Cost Aooonnting system for
a terminal Gr ain Elevator . It seems desirable to introduce t h e subject with
a brief survey of terminal warehouse facilities in the Twin Cities, a descrip
tion of the equiprrent a.nd operation or a terminal elevator, and a statement of
the necessity 01" a. cost-finding system, and the problems connected with it
for this type of business .
2. 1/arehouse facilities of the Twin Cities.
There are two major classifications of grain a.rehouses, Regulal" and
Private. The latter are operated for the use and benefit of their owners ho
are companies engaged in some specific brnnoh of the grain trade. The flour
mills own and operate large storage a.rehouses in which they store their Wheat
until it is desired to mill it. The warehouses of this type are the largest
in the 'I'win Cities , and the capacity o£ a. few is given.

'J:he latter house is classed as a regular public a.rehouse, but it is used to

It is seen from these :figures that the capacity of the terminals as used

number of tL.::es than the smaller handling houses owing to the nature of their
operations .
6 Description of a Terminal .:a.rehouse . Let us nav proceed to a desc:c"iption of the ~arehouse itself . :i:"nere are
two portio1:s of the structure vlhich are four.d. in all terminal elevators . '&ese
are the storage bins and the head-house , and they are found in some form in
every large elevator . Plates I and II shm these two portior.s very plainly
bot_h in floor plan and in side elevation, the taller portion being the h~
house and the group of circular structures the storage bins . In the head-
house is done all the bani.ling of the grain; the cleaners are located here,
eighing is done here . A ref'erence to Plate lo. IV sh s that the head-house
is divided into a number of' smll bins , a total of t enty in this ir.sta.nce.
These are used for the purpose of holdin0 a.in temporarily, fo exmnple,
clenn grain that is 1aiting to be loaded into a car , or dirt that has been
cle.:i.ned out of g rain. Grain >;hich is run thru the house or the purpose of
transferri!1£: it from one car to another is put temporarily in one of these
bins . The cross sections o ... the head house , shown on Plate IV, can be
easily found on the side elevation on Plate II . In this instunce the cleaner
floor is at about a third tho height of the head-house, but is usually found
in '.i:'win City houses on the gr ound floor.

The shipping leg takes grain fr an the bin am dumps it into the garner for
Weighing out .
lO loading equipment .
A side view of the equipment used in unloading cars is indicated. on Plate
III , i; hile on Plate I its location on the floor plan is given. The grain is
thrown rrom the car 'by means of broad ooien blades •lhich scoop it out . These
blades a.re pulled by steel ropes which pull and release alternately, and they
are guided by workmen who plunge them into the grain and guide them to the car
door • After all the grain possible is gotten by this method, the orlonen sweep
the oar to get all the grain. As the grain leaves the oar it falls into a pit
directly under the car . t the bottom of the pit r'lms a broad eildless belt
whiab. takes the grain to the boot of the receiving lE€ •
ll•Loading Equipment. This form of equipment is much siopler than that for unloading. It c cmsi sts
of a spout leading ~ rom the bottom of the scale . This spout ends in an aajus-
table s 1iveled spout vihioh can be directed. to all parts of the car. '~e car
spout is shown in Plate III . The grain is spoutea. to tne oar by gravi • It
is leveled off by ::t:and and the aid of the adjustable spout .
12 • Conveyors . Grain entors t he elevator thru tne head-house ana. then is t en to the
st oraee bins on a wide endless belt , the convcyer belt. ~is belt r-uns t u a.n
alley between the tops of the d ou.ble row of bins rUIIIlin.., over rollers so placed
that its surfa.oe is concave. There is also one on the ground loor, !lich takes
the gr a in m:1ey fr an the bins . Grain is delivered to this l er belt by gravity .
It is delivered to the upper belt cy the recei vinG leg. In the upper belt is
a tripper or a_pparatus for aubl ing back the belt. '~e tripper is on a
movable oar ~hich can be placed in :f':ront of e:ny desired bin. The velooit
of the grain throws it ozf the belt into a chute ich lro.ds to the bin. Both
upper nnd lo .er belts and tripper are shcmn in Plate II.
rri=========.i 6. 13. Course of Grain thru the Elevatol" .
Let us now take up the operation of the house; tracing the course of the
grain in its progress into and :from the house and during its 11.'.lndlinz v1hile in
the house .
The incoming car is spotted directly over the receiving pit , and the grann
is dumped therein. Plate III shows the track-shed, pi tx and ca.rs in place .
The belt conveyor takes the grain to the boot of the receiving leg honce it is
elevated t o the garner at the top of the house . fast as the eigher ~eishs
the grain, it is dropped to the boot of the elevating leg from hich it is
elevated. to the upper conveyor belt . From this belt is is thr n into the
proper storage bin.
14. 'ilie reverse o ... this :procedure takes plooe when grain leaves the storage bim .
It is let onto the lower belt thru the spouts shown in Plate II , and taken t o the
boot of the shipping leg. Tb.is discharges it into the garner rrom hich it e oes
thru the scale as before . .li'r om the scale it oes to t e car spout and is
delivered into the car .
15. L.:.oving ar.d. Conditioning •
.. hen grnin is in sto'.!.4age ·t is not al eys possible to leave it in t e tank
until it is desired to ship it . Someti~es it is stored at such hi~,h temperatures
th~t ir l eft alone it ~ill heat ands eat a.nd cause ~reat deterioration. If i•
has a high moisture content it is more likely to get out of condition than if the
moisture c antent is lo • :Wuch valuable scientific inves igation has be o on
this sub~ect , but it is not pertinent to this paper , hioh is oonoer-ed ith the
actual practices of terminal elevators .
The results of this investigation shcr.7 that grain 1hich · a.s a moisture
content above 14% iill not keep ell. Thora ore grcin is graded lo.er en it
has a hi_;h moisture ccmtent tha."1 ·;hen it has a lOVl percentage of moisture.

This do es not mean that Wheat which 3rades umber i ve i7ill keep 1i th
16,G moisture. It means that it will not keep as ell a.::;d is there ore gro.ded
down.
The method adopted and practiced by all terminal elevators is to '-cep
the erain moving . Durin..g the winter , theseasoi:able loo temperatures are
utilized by taking the grain f'r an the bins, ciu::ipil".g it into the recei vi. g pit
and returning it to the bins . This process effectuall oools t- e gr.3.in. It
also aerates the grain and tends to dry it . common remark in :m elevator Tihile
gruin is being moved is "You can hoo.r it now" ich means the grain is d
enough to make a scratching sound as it runs thru the pipes .
16. ilie grain is taken fr om the bin by the looer belt conveyor, elevated
and dumped into the receivin:; pit . ~rom here it is taken to the elevating lEe,
elevated to the u.;_)per co-veyor , a.r.d thence back to the bins. This operation is
bein.:; ca:rriei on constantly in order to move all ti e grain. lFlll'L~ the season,
all the grain in the house is moved at least t ioe.
17 . hlixing. Another operation of terminal elevators is mixi ~ of grain of
different grades. The ethics of this much debated question a e not pertinent
t o this paper. The fact is that, since it is being done dai , it constitutes
one of the operating costs of a terminal elevator, 3.Ild so its econ<Xlic speots
must be oonsidered. . '.i..rne object or mixing is to raise the rade of era.in so t:. t
it ill bring a higher price. ong other considerations , grain is graded an the
eight of a measured bushel . mus
.t·lo . l heat must eigh not less th:ln 58 pounds per bushel

a • . 1heat which weighs 56- 1/2 p ounds per bushel would there ore be graded r;o. 3
and it will at once be seen that it wil l bring no better price than v.hea.t which
just makes the grade at 55 potznds per bushel . me profit from mixing is nnde
possible by this fact . An elevator hich has some grain ~hich is h eavier than is
necessary can mix it with some that is lighter and still retain the hi her grnde.
Or it can ta1re grain of two different grades and mix: them in order to make the
resultant coni'orm to the grade between the t 10. This would be one when the aver e
price v1ould show a pr of it on the operation. This is e:x:pla · ed in the follcming
illustration.

19 . .After the calculations have been made and the decision arrived at,
the aatU3.l rnixin.-; is dcne . ~e fl0\1 of groin from the bil s is re0 ul.ated by a
device known as a Graver feeder , 1hioh con be adjusted to deliver any desired
amount of grain . 0i~e bin is set to deliver 54 pounds in the same ti the
9 . other delivers 57 pounds. .i:ne t~ o streams run onto the same belt and are
thoroughly mixed. '.Che combined stream is thrown into the boot of the
elevating leg. It is then elevated to the upper conveyor belt a.rd dl.lllp:ted
into the bin containing ·3 Dark 1;-orthern ./heat. '.11h.is ~ be done to ill
particular orders or as is usual it rD8;J be done deliberately as fotmd
convenient through the season.
20 • Cleaning i1h are are three fundamental reasons for cleaning grain. ~e first is that
Th ea.t is not suitable for milling when mixed rzi th other seeds . :J.: e second i a
that the by-pr oiucts (or the seeds that are separated. from the grain) are
valuable. 11ie third is that the grade of a grain like oats may be raised by
cleaning. Any one of these reasons 1ould probably impel clean • In the case
of oats, a. grain which carries a husk or shell, the presence of loose husks
i70uld greatly lessen the weight pel' measured. bushel of oats of a high qu.:ilit •
~ho removal of this loose , light material is therefore a 11payL pr opos i ti on" .
21 . 13.l"me rs occasional)¥ plant \lhat they call succotash, a i:ixture heat
and oats. 1fue resulting orop is about a half and half inixture. ... ere i often
a c cnsiderable a.mount of volunteer oats mxed in heat . ihether cultivated or .
lild oats, they are valuable when gotten out . Other forei n seeds, such as
buck- heat , weed seeds , and other non-cereal seeds fom;.d in ,. eat , have a
varying value. The treatment of screenings oan be II13le profitable by ag n
separating the by-product into :f'urthe. classes to be used s poultr and stoc •
feeds . On '.arch 22, 1922, a car of screenings sold at 9. 00 per ton, and
t11ey lnve been quoted as high as 20 . 00 and 22. 00 P tan. ~~us it is sh cmn
that the value of the by-pr cxlucts is a. stimulus for clean " and separ tir.g
grains . 22. If all foreign seeds and material ere enti ely valueless it .ould still
be necessary to cloon <->rain. ~lour lls , ;hich form the chief . .-a.rket or
whoo.t , :ijave developed the h:m.dling o heat in the mmiufa.cturi.ng of flo'J.:r to a
lo . lii3h degree of per:fection. '.J.'he publ ic has been educated. to use J11ito flour
and it is the business of the mills to supply it. Any ingredient in ea.t
whieh wil l darken the flour or in any other ay injure its baking qualities
lcme:rs the value in the eyes of the miller . '.l.b.erefore, th cleo.n their
wheat ags.in ar..d again until it has an ad.mixture o ... foreit;n materials so smll
that it does not injure the flour .
23 . Cleaning Equipment .
The equipment used in cleaning varies from the co. n fanni ng mill ound
on nearly every farm to the high capacity ru.chi~~e y;hich separates and oleam
in the terminal elevator or the flour mill. :me principle o the sieve is
an old one , in fact the sieve is one of man ' s oldest implements . It depends
:for its act ion on the difference in size of p~ticles to be separn.ted . nus
if one were to run \:heat mixed with oats ar-d eed seeds over a sieve i th holes
lareer than ;wheat but smaller than oats , the oats ouJd be 1 t behir..d.
~'u.rther if he ere to run tho heat and 1eed seed mixture over a sieve .it
holes sr.::aller than ;;heat , he would sift out the smller seeds d leav
1hea.t . 'l'his is the underlyi ig :pril:c iple 011 hich separators are uilt , llltho
there is an in.fir.i te number 01 variatio .s in the .~chi es o ifferent IAl.'.lKes .
24 • .i.'here is a.nothe:r principle used in cor.nectiOZl iith the above mentio ed one.
That is the fact that 1:hen a. mixtu:re is itated , the li_,hter rticles co
posing it rise to tre top. '.i.1hus in a. mixture o t eat ru1d oats , the rots
1ould come to the top been e they. e · h but apprax:i te · lf as much.
•1v:mtago is taken of this act in rw:ning the rain over tho sieves . .i1£l
sieves are g iven a side- ise shaking motion jiich catlses the .~ea.vier oo.t
to go to the bottom ere it i ediatel.y alls th u tho holes in the sieve .
i'he oats rise to the top and as lo. ' as there ·s s:ny · at the nili.:tur e the
clo not touch the sieve. .".hen all the heat has .1£. ssed thr t e oats rest
on the sieve and of course h::i.ve a tondoncy to go thru. ~U!l tho cle3.l'ling
is most thoro tho first third of the sifter surface and leas~ thor 0 tho la.st
third . To adjust this so that cleaning is most efficient is the problem of
makers of cl mners .
26. •>'hen the grain has passed over the first sieve, the rots ru d lar..,er

no q_uesti on that d ooka.ge often has a high value, but on the other hand
much d oc lm.ge is valueless , for example, sterm, chaff, s21 , dirt, stra :.

the fr i ction involved in moving it is less. Clean Wheat ~oles more fi1'lll4"

9. ~lanation ot .ttesults.
me o a:i.ollusion is contrary to the implioatiC11 1n paragraph fi ot thi
section, that increase in dockage c<:11tent should r ult in 1norea.s oleanin8
costs. ·.i:he reas en is not tar to seek. Oats, barle;v, stem and chaff' ar all
appreciably l1g:b.ter than Wheat, and the more th.En"e is of' them in the ixture,
the lighter 1a a g1 ven bulk of the mixture. '.!!his being true one woald expect
power consumption to decrease pr <gl'essively as dool$8ge 'is ind.'eaaed, and the
mixture beoomes lighter and bulld.er. .But it do not do so, a is shown ill
Table VI. Clean Wheat consumes the most, and the amotmt deoreaa tm.til :tour
per cent of dookage is .reaohed. 'J!he addition ot the next one r:er oent of
4 · 22-8M
?.()
dooka8e shOllJB n increase, but this does not persist as at eight per oent"
the power cmsumed is again as low as 1t was at fror pe'I!' oent. The reason
tor this is that as fOJ!eign matter incx-eases the grain will go thru the
separator more slow~. The longer time consumed means an increase in power
ccnsume:l. ·.1.'he ahange makes its appearance at the point vih8l'e t'iTa per cent
ot doakage is present, but the downward tr8Dd sets in again and tor the ame
reason.
'l'hus, it appears that there are two compensating forces, on or time
am. one of' weight and fl'iction. me benefit caning from lessened weight a.DI
t'riotion is compensated 'h3' lessene:l cleaning ca:pe.oity. If cleaners in terminal
elevators •ex-e coopelle:l to operate at utmost capacity at all ti s in ol"der
to get the work d cne, this might be a serious OOl'l.S ideration. 'they are not so

l. Some analysis and comparisons bet een our results and
figures and rates now in use will now be made.
2. Storing.
We have seen in Paragraph 5, Section 1, that the terminal
elevators of inneapolis used their capacity 3.04 times in
handling the 1919 crop, the public houses more ti es, and the
private and tank houses less times than the average. Let us
see hoi this co pares with our results. If our volume is 2,126,338
bushels and our storage capacity 500,000 bushels, our capacity
was used 4.25 times in handling the voluzre. From this f i gure
can be calculated the average length of time the grain re~ained
in the bl)use, by dividing the year or t elve onths by 4.25.
The result is 2.S2 months.
3. The total storing cost divided by total volume gives t he
cost of handling one bushel for t he average length of storage.
Thus 39,683.lS divided by 2,126,338 gives 0187, the cost of
storing 2.82 months. Reduced, this figure is .00663 as the coat
of storage for one month, When the elevator is used to capacity.
The legue rate for storage charges is one thirtieth of one cent
per day or one cent per month. Thus the maximum margin for man
office expenses, salaries and profits, ould be 00337 or 33 1/3%
of the income from storage charges.
4. It is obvious that the average terminal el v tor is not full
to capacity at all times. The grain crops are largely marketed in
the fall, and during fall and inter the elevators a.re taxed to the
full capactiy. During the summer this is not true. As heat is
4·22·8 M
37. constantly being milled, the old crop is approaching exhaustion
by the time the ne~ crop is marketed. It would have been inter-
eating and valuable if the facts could have been secured showing
the actual amount of grain in storage in relation to total capac
ity. The officials of the inneapolis Cha ber of Commerce could
not furnish this information, ho ever, and it as not contained in
a usable ~ay in their annual report . This information is neces
sary, ho ever, if the present findings are to be applied to the
business of any specific elevator, or if they are to be used to
determine the fairness of rate charged by Terminal lev tors. The
per unit (per bushel) cost f handling grain is increa ed n the
margin of profit is decreased hen tne quar~ity of grain h ndled
in an elevator is decreased, either by using the c pacity a portion
of the year or by using only a portion of the ca acity t ou h the
year.

5. The above table is calculated on the c p city nd vol e of
business used i n the calculation in pa.ragraph 3, and the c pacity
being utilized to different degree, but the hou e bein aper ted
the year around. This is the practice in terttical elevators, the
management of which attempts to keep some kind of grain in their
bins at all times whatever ill pay them their handling charge.
The table points out t.e tendency of costs to increase rather
rapidly as the degree of utilization of storage capacity decreases.
It is therefore apparent that the degree of utilisation becomes an
important part of the application of this system to the amounts
of specific companies. The records of the company ould ~·~lo tbe
desired information tf the daily or eekly amounts of stored grain
were averaged and the result compared with the total storage capac
ity.
6. It should be observed that in the above calculations the
coats of operating the terminal elevator are regarded as fixed.
Thia is substantially true. The practice is for the elevators to
maintain a full or maximum ere througho~t the year - by this means
obviating the necessity of training men each fall in the busy
season. Overhead expenses , such as depreciation, interest, taxes,
etc., are constant throughout the year. The chief items of ex
pense which vary with volume of busine s handled are po er, 1nsura.nc
on grain in storage and taxes on grain in storage. A terminal
elevator operates under decreasing costs and by reducing its stor
age activities,- it increases its per unit costs. Ho ever, in so
far as the costs vary directly ith the volume of business, they
do not increase with a decrease in the quantity stored. In apply
ing this system to the accounts of a specific company, no special
calculation is necessary, as the actual expenses incurred and the
actual degree of utilization a.re both determined.

7. Cleaning.
The total cleaning cost is 9,471. 61 and we ish to know the
cost of cleaning one bushel. e have already assumed that all
grain is cleaned, and the amount is as before 2,126,338 bushels .
The cost of cleaning one bushel is, therefore, . 00445 hen grain
is cleaned while in storage. Let us analyze this further •

Thus cleaning costs are 14.83¢ per ton.

This is more involved and a more expensive process since it
comprises unloading and loading, elevating t ice and cleaning.

The above costs do not include transportation of dockage fro
the elevator to the place of utilization. If the elevator retain

Chapter v. - Conclusion.
It h s been su gested in e rlier pa.rt of this paper th t
ter~in 1 elevators do not use cost ccounting metho in the con-
duct of tneir business . Thi does not me , ho ever, t t they
a.re not applicable to the grain bu iness. he syste devised n t i
paper could be pplied to a.ny ter inal warehouse. Slight modific
tiona ould doubtless be necessary to suit individual ca e • e
distribution of t e pri ry accounts should be change to meet
requirements . The underlying pri~ciples, ho ever, ill apply to
the business of all terminal elevators. It is the op-nion of men
in the grain trade that costs should be allocated over a crop year .
The 422•8M
41 .
The handling cost thus obtained would be an average cost. If it
iere desired to obtain monthly costs distributed over the volume
of business handled during each month, there is no reason why it
could not be done. Depreciation, interest, prospective taxes for t
year could be divided into monthly parts . Current expenses, such
as labor, power, repairs, etc., are easily gotten by the month .
The volume of grain handled, the degree of utilization of stor ge
capacity can be determined each month . The system thus is seen to
be an elastic one, meeting the needs of the grain trade, lending
itself to adjustment to eet varying conditions . The infer ation
obtained by a general application of coat finding to terminal
elevators shoula prove valuable in the problem of putting a fair
rate for storing, cleaning and other services of Terminal Gr in Ele
vators.
