wheat under federal standards one Of
the fundamental principles Is to deter

the dockagc Is first removed from the
samples and the Ernde determined

DOckage Is the foreign material

graded by the use Of appropriate hnnd
sleeves or other cleaning devices, and
consists OF sand. dirt, weed seeds, weed
stems, chan. straw, grain other thnn
wheat, and any other foreign material.
II also may contain finely broken or
small, shriveled grains OF wheat, In
cases where such material cannot he
separated from dirt and other foreign
material by the use Of appropriate
sleeves,
! Foreign Material Determined.
The purpose OF the dockage prov!-
sion in the federal wheat standards Is
TO enable the person grading the sam.
Pile 10 determine the approximate
amount of easily separated foreign INA
terial that Is In the lot OF wheat
Therefore, dockage Is approximately
the percentage OF foreign material
which can be easily removed from the
lot OF wheat by the commercial types
of cleaning machinery commonly found
In grain elevators and mills.
The dockage test Is described In
Farmers Bulletin lllS entitled Dock
age Under Federal Wheat Grades"
which has recently been issued by the
United States department Of agricul.
ture 20 aid wheat growers and Others
In understanding this important fea'
ture OF wheat grading as provided ID

wheat, which became effective July 10,

pockape Test Described.
The dockage test Is made ordinarily
by weighing 1000 grams OF wheat
tabout az pounds), which constitutes
a representative sample. Grams are
used instead OF other units for ease in
determining percentages. .
The docknge is separated from this
1000 gram sample by screening with
pan sleeves Of specified types or by
using cleaning device which has been
officially approved, The dockage so
separated is weighed and the percent
age is found, based on the total weight
of the sample Including the dockage,
II the amount OF dockage Is below
per cent IL is disregarded. For exam
pie, II only one.hnlf Of per cent OF
foreign material Is separated by the
described above, no dockage Is
assessed This one.half of per cent,
however. should not be returned to the
sample used In determining the grade.
II ~ per cent Of dockage Is separat-
ed, per cent of dockage would be In.
dicated In assigning the grade. Thus
II will he seen that any fraction OF
per cent Of Iockage Is considered as n
IN the standards.
Indicated In Certificate.
After the dockage is removed the
clean sample IS used In determining
the grade, save In a few exceptions,
Dockage does not affect the grade Jas

more OF separnble foreign material is
found, dockage is assessed. In the In.

selected. cleaned, tested and treated
before planting. II care Is exercised III
and crop rotation, ana "
the wheat is carefully threshed and
cleaned. there should he, ordinarily,
very little foreign material present
when the crop Is marketed.
Apply to Foreign Material.
Two terms In the federal whea,
standard apply 10 foreign material
and foreign material other
than dockage." The former Is foreign
that is separated from the
sample Of wheat by the proper use OF
hand sleeves. "Forelgn

foreign material not separated In the
