A new form of fat that has rapidly come into our market is the oil of
the soya or soy bean. In 1918 we imported over 300,000,000 pounds of
soy-bean oil, mostly from Manchuria. The oil is used in manufacture of
substitutes for butter, lard, cheese, milk and cream, as well as for
soap and paint. The soy-bean can be raised in the United States wherever
corn can be grown and provides provender for man and beast. The soy meal
left after the extraction of the oil makes a good cattle food and the
fermented juice affords the shoya sauce made familiar to us through the
popularity of the chop-suey restaurants.

As meat and dairy products become scarcer and dearer we shall become
increasingly dependent upon the vegetable fats. We should therefore
devise means of saving what we now throw away, raise as much as we can
under our own flag, keep open avenues for our foreign supply and
encourage our cooks to make use of the new products invented by our
chemists.

FIGHTING WITH FUMES


The Germans opened the war using projectiles seventeen inches in
diameter. They closed it using projectiles one one-hundred millionth of
an inch in diameter. And the latter were more effective than the former.
As the dimensions were reduced from molar to molecular the battle became
