this patriotic appeal were well rewarded, for cotton rose as the war
went on and sold at twenty-nine cents a pound.

But the chemist has added some $150,000,000 a year to the value of the
crop by discovering ways of utilizing the cottonseed that used to be
thrown away or burned as fuel. The genealogical table of the progeny of
the cottonseed herewith printed will give some idea of their variety. If
you will examine a cottonseed you will see first that there is a fine
fuzz of cotton fiber sticking to it. These linters can be removed by
machinery and used for any purpose where length of fiber is not
essential. For instance, they may be nitrated as described in previous
articles and used for making smokeless powder or celluloid.

On cutting open the seed you will observe that it consists of an oily,
mealy kernel encased in a thin brown hull. The hulls, amounting to 700
or 900 pounds in a ton of seed, were formerly burned. Now, however, they
bring from $4 to $10 a ton because they can be ground up into
cattle-feed or paper stock or used as fertilizer.

The kernel of the cottonseed on being pressed yields a yellow oil and
leaves a mealy cake. This last, mixed with the hulls, makes a good
fodder for fattening cattle. Also, adding twenty-five per cent. of the
refined cottonseed meal to our war bread made it more nutritious and no
less palatable. Cottonseed meal contains about forty per cent. of
protein and is therefore a highly concentrated and very valuable feeding
stuff. Before the war we were exporting nearly half a million tons of
cottonseed meal to Europe, chiefly to Germany and Denmark, where it is
used for dairy cows. The British yeoman, his country's pride, has not
