old storage
has enabled the fruit growers of California to supply the eastern
markets with peaches and other fresh fruit. Chicago, to give only one
example, begins to receive strawberries, cabbages and tomatoes from
the shores of the Gulf of Mexico early in the year and continues to
receive these products, until finally they are being shipped late in
the summer from the shores of Lake Superior. It is estimated that the
change of locality from which these products come, travels northward
at the rate of from 13 to 15 miles a day.

IMPORTANT FACTORS IN INTENSIVE FARMING

In the neighborhood of large cities, notably in the environs of Paris,
market gardeners often produce their vegetables in made soil. The
local character of the soil under such conditions is a matter of
comparative indifference, since a board floor would answer every
requirement as a resting place for the artificial soil. The large
expense in preparing and constantly renewing the seed bed is only
economically possible, however, where proximity to a large city
out-weighs all other considerations.

Ordinarily climatic and soil adaptation are prime factors in
successful horticulture--much more than in any other branch of
agriculture. Each fruit has a restricted climatic range, and in most
cases the number of soil types on which a given fruit can be made a
commercial success is likewise limited. Thus, in general, apples and
pears require heavier soils than peaches. Success in commercial apple
growing requires even greater discrimination, since different
varieties of apples demand different soil conditions. Thus Baldwins
are grown the most successfully where a northern climate is modified
by proximity to the Great Lakes. Rhode Island Greenings will succeed
on soils too heavy for many other varieties. The York Imperial has not
yet achieved a great commercial success save on one type of soil. Some
varieties of apples are much more restricted in their adaptation than
others. Thus, while the King is quite restricted, the Ben Davis has a
fairly wide cultural adaptation. No one should plant an orchard until
he has made a thorough study of his soil and climatic conditions and
has received the highest possible expert assistance in choosing the
varieties best adapted to his conditions.

There is an increasing tendency to specialize in vegetable growing.
