lFse a certificate of grade for any grain unless
the inspection and grading thereof be based
upon a correct and representative sample of

permit the determination of its true grade.

IegLaI 3&on 5 of the regulations of the Secre-

Melie of the, Secretary, United States Departe-
lilne of Agriculture, states:

a wagon, at least five probes (with a double-shell
compartment trier 60 inches long, or one giving
equivalent results), and as many more as may be
necessary in the discretion of the sampler, shall
be taken from the grain in different parts.of the
car or wagon, as the case may be.

double-shell, compartment trier, or one giving
equivalent results), and as many more as may be
necessary in the discretion of the sampler, shall
be taken at points through each hatch or opening
in the deck, or may be drawn from the spout or on

in such a way as to be representative of the entire

In case of bulk grain being loaded aboard a
canal boat, barge, ship, or other vessel, the sam-

acetate solution. The test tube-shoilld not be
over three-fourths full of lead acetate stion,
in order to prevent spilling when the ia begins
to pass over.
The delivery tube should extend to within
1 inch of the bottom of the test tube. If the
grain has been sulphur bleached, the eom-
ing over will combine with the lead acetate
solution and produce lead sulphid, a ';"r nish-
-black precipitate. If the grain has .. been
sulphur bleached, the liquid in the te tube
will remain clear. Should the grain i very
dirty, fine granules will occasionally, e seen
held in suspension in the acetate soltit i. in
the test tube, and- the same condition will
obtain if the acid is: too strong. Thi" fine
precipitate should not be mistaken for lead
sulphid. To test these granules, addii- t he
test tube a few drops of ferric ehoide (1
part ferric chloride to 10 parts distilled water).
If they are lead sulphid they will dissolve imme-
SPECIAL POINTS FOR CONSIDERATION
1. It is essential that either mossy or granular
zinc be used; other forms are not sais~fMttby.
2. A preliminary blank test, using everything
except the grain, should be run with every test,
and the results compared with the test .n the
3. At times, because of the purity.,of the
zinc, the action between the acid and the zinc
is slow. The action may be nMade inmokre vig-
orous by adding to the flask & few drops of a 10
per cent ferric chloride or copper ulphate
