digestible, and a large number are
high in protein and low to medium in
carbohy drates. The concentrated feeds
are fed with the home grown coarse
feeds, therefore, first to increase the
digestible matter, and second, to in
crease the amount of protein in the
daily ration.
There are four classes OF these con.
centrated feeding stuffs, as follows:
Glass 1 contains 80 to 45 per cent. of
protein, 80 to so per cent. of carbohy.
drates Gncluding fate) and are rs to 80
per cent. digestible. This class includes
cotton seed meal, linseed meal, Chicago
gluten meal, cream gluten meal, King
gluten meal, and Hammond gluten
meal.
Glass 2 contains 90 to 80 per cent.

drates, Gncluding fats), and are 80 to
s5 per cent. digestible. These include
Buffalo, Golden, Diamond, Davenport,
Climax, Joliet and Standard gluten
feeds, all made from corn, Atlas meal,
dried brewers grain and malt sprouts.
Glass 8 contains IL to 20 per cent.

and are so TO 10 per cent. digestible.
These include wheat bran, middlings.

Glass A contains s to IA per cent. pro
tein, rs TO IS per cent. carbohydrates
and are 76 TO 90 per cent. digestible.
These include wheat feeds, barley
feeds, oat feeds, corn, feeds, cerealire
feeds, hominy feeds, corn chops, oat
chops, corn germ feeds and chop feeds.
The seed Of the cotton plant as it
comes from the gin where the cotton
fiber has been removed is still covered
with coat OF white down technically
known as ''linters." This being re
moved, the seed itself appears as black
in color and irregular egg shaped in
form. The thick, hard, black seed
coal or hull is filed with the coiled
embryo (meat), which in turn contains
large number Of oil containing cells.
Machines have been invented to re-
move the hull. The meat in then cooked
in large iron kettles, and while still hot
is wrapped in hair cloth, and SUBJ jscted
to pressure Of 5000 to 4, 600 pounds
per square inch, to remove as much of
the oil as possible. The pressed cotton
seed cake is cracked, ground and re
suits in the decorticated bright yellow
cotton seed meal of commerce. A ton
Of seed furnishes about 800 pounds Of
meal. Sometimes @ considerable
amount Of hull is ground fine and
mixed with the meal, producing q
dark colored article, having not much
over one half the feeding value of the
prime material.
In like manner, linseed meal is pro-
duced by grinding the cakes Of fax
seed after the oil has been pressed out.
Most of fax seed used i'm America ia
grown in Minnesota and the two De-
kotas. The old process linseed meal
has had only the oil moved that could
be pressed out; the new process meal
has had additional oil extracted by
treating it with solvent chemicals after
it comes from the press. The former
is very properly called ''oil meal, the
latter contains very little oil.
This question of feeding and feeding
stuffs is an important one. Believing
that our farmer readers should study
these questions more, we will in next
weeks PROGRESSIVE FARMER have
something more to say on this subject
and will also give q list of different
feed mixtures recommended by the
Massachusetts, Station.
