New York.-The diet of Americans
| will be changed rapidly. as the growing
| population presses upon the food sup
| ply, but 1t will not be necessary for us
| to become entirely vegetarian. This
Is the conclusion reached by Professor
j.. Il. Lyman of the Ohio State uni
versity after a study of the available
food supply of this country. published
In Popular Science.
There was no food problem in this
| country two generations ago, when fish
were plentiful. pigeons. deer, wild
| turkeys. waterfowl. quail and buffalo
| were abundant and wild berries, fruit
! and nuts could be obtained easily and
in large quantities. With the growth
| of population, however. game practical
ly has disappeared and a very small
| part of the country's food is supplied
by u%ncultivated plants and trees. DIR.
Lyman says:
IF the present rate OF increase con
| inues the population of the United
| States will approximate 500,000,000 at
| the end of the present century. Is 1t
| possible to feed that number of persons
on the product of our 3,000,000 square
miles? China and India both support
| a population as dense. but both of these
countries are distinctly agricultural.
| The mass of people live on the land
and are engaged in producing food. In
this country the great increase In popu-
| lation is in the cities, while the food
| producing class is increasing compare
lively slowly. The reports on agricul-
tural products exported from the
United States illuminate the food prob
lem in an instructive way. IL we com
| pare the exports in 1912 with those for
1900 we find that the amount of cheese
| shipped abroad declined IS per cent In
that period, beef products declined 65
| per cent, pork products declined 30
| per cent, corn declined so per cent.
wheat declined 81 per cent
what do these figures tell? Simply
| that we have needed the food at home
to supply our increasing millions and
| hence had less to sell In the markets Of
the world. Can we continue to feed our
people by reducing the exports In food
stuffs? Obviously not, and In many
instances they have been reduced al
ready near the vanishing point. We
have even actually begun to import
meat and corn. 1t is significant also
| that free government land suitable for
agricultural purposes Is no longer avail
able; hence we cannot look for relief
by bringing under the pillow large tracts
| Of virgin soil.
rs there likely, then, to be scarcity
| of food I'm this country In the near
| future? No, there is and will be plenty
of food, but some changes In dietaries
undoubtedly will have to be made.
Let US notice. In 1910 for every man.
woman and child In the United States
there was produced seven bushels Of
wheat, ~thirty-two bushels of corn, four
bushels of potatoes and forty pounds
of sugar. There were six-tenths cattle
for each person. six-tenths sheep and
seven-tenthS swine. Add to this the
fruits, vegetables. poultry and dairy
products, oats and other small grains
and we see that there Is plenty Of food
to go around and to spare.
There was grown In the United
| States In 1912 corn which. IL assembled
In one immense field, might have COW
cred Germany or France entirely with
its rustling phalanx. How many mil
lions might be nourished by the prod
uce of this tremendous acreage. Here
is a great source of food at present
utilized in a very slight degree.
"Food has two primary functions In
the b~ody-frst. to supply material out
Of which the body is built and, second.
to furnish energy to warm the body
and to drive its machinery. Perhaps
the second function is the more i'm
portant. Plants alone have the power
to collect solar energy and store it up
In a latent or dormant form In their
seeds and other parts. Animals may,
by eating and digesting these plant
materials. liberate and utilize this
stored up energy. When corn Is fed
to steers under favorable conditions 3
per cent of the energy Of the corn may
be recovered as meat In the edible por-
ton OF the carcass. The remaining 81
per cent was used by the animal in
Its various activities and lost as far as
the nutrition Of man is concerned. In
pork the recovered portion amounts to
10 per cent. and with the dairy cow Is
per cent Of the energy Of the food IL
found In the milk produced. Obviously
this il q wasteful process. this con-
version Of grain into meat and milk.
It has its justification only in the great
er p~alatability and d%igestibiiity Of the
dnal products.
