Hanging In one of the rooms occu-
pied by the main Office of the bu-
reau of markets, United States depart
ment of agriculture, in Washington, is
q map showing an important phase Of
the governments work in interesting
grain growers, dealers and millers in
grain grading. The map is dotted
with many colored pins, indicating
towns and villages, scattered north
south, east and west, where this truth
has been emphasized in connection
with grain-grading demonstrations,
given by Representatives of the bureau
The map is an eptome of the grain
of grain grading.
Grading Made u. dcrstandable.
1t is not easy to explain grain grad
ing If one attempts it without samples
or apparatus, but with the equipment
included in travelling exhibits sent out
by the department it is much simpler
matter With the help of information
given by the demonstrators a farmer
familiar with grain can soon learn to
grade his own crop satisfactorily.
Prior to the establishment of fed
eral grades. growers and interior buy
ers knew little of the various methods
and interpretations of different local
grades at the grain terminals. Under
federal standards the government
shows how the grading is done accord
ing to definite rules of one national
standard, so that the farmer and in
terror dealer have access to the same
knowledge of grain grading as was for
merly had by the terminal dealer. The
exhibits are designed to show the cor
rect methods of applying the federal
grades for oats. wheat and shelled
corn. The apparatus displayed in
cludes a moisture tester, scales for
weighing samples and separations, a
test weight-per-bushel device, a $50
50'' separating device, sieves and a
wildcat kicker"
To visitors interested In learning
how samples of grain from a car or
bin are secured which are truly repre-
sentative, it is explained that a
sampler makes probes in five or more
different parts of car with tubelike
instrument containing ten compart-
ments. With this he secures grain
from various depths Of the load. The
contents of each probe is emptied upon
sampling cloth and examined for
odor, temperature and condition. A
portion of the sample Ia put in an air
tight can and the remainder In H'oth
bag. These two lots are then BROUGHT
to the inspection office for examina-
ton, testing and grading.
But the visitor objects, such sam
Piles are too large for testing and for a
detailed examination Of the kernels.
That Is true. That is just the reason
for the "5O-50" machine. the demon
strator explains. The sample from he
bag Is poured into the hopper at the
top Of this twO-spouted cylindrical ma
chine and cone-shaped battle, located
Just below the outlet of the hopper,
causes the grain to spread evenly over
its surface. AT it's base are a series OF
ducts, each alternate duct flowing into
one of the spouts below, which &C.
curately divides the sample in half SO
that one portion of 1t will grade ex-
actly the same as the other. Five or
six divisions of the sample are made
in this way to reduce the portion to
be examined from about Az pounds To
from one to nine ounces, depending on
the test to be made. This enables the
inspector to analyze the sample rap
idly. Part Of the loose saraple is put
through the test welght-per-bushel ma
chine. The value Of this device lies In
the fact that with all samples weighed
the kettle is filed under uniform con-
ditions. The sample falls just two
inches from hopper to the quart ket-
tie, passing through an opening ~
inches in diameter.
Use of Type Trays.
When the examination Of the indi-
vfdual kernels is undertaken the in
quirer at the exhibit sees the value of
the glass-covered type trays to the
demonstration il corn is being ex-
umined the demonstration picks up a
tray showing kernels that serve as
types to determine whether q sample
classes as white" ''yellow" or
mixed" Another group of kernels
shows various types of damaged ker-
nels.
If the grading of white oats is being
demonstrated. another tray is used. If
wheat is under discussion the inquirer
