rds soil and climate, which is adapted to the crop
or crops to be raised, yet there are probably more failures due to a
lack of crop adaptation than to any other cause that is not personal
to the man himself. Not only do apples, for their best success,
require certain soil types, but different varieties of apples require
for their best development, distinctly different types of soil as, for
example, Rhode Island Greening, Baldwin, York Imperial and Grime's
Golden. Each reaches its best development on different types of soil
and some require different climatic conditions. In like manner apples
and peaches require distinctly different types of soil for the best
success of each and for this reason peaches are not desirable as
fillers in apple orchards.

If at the proper season of the year one goes from Pittsburg to Chicago
via Columbus and Indianapolis, he will see great fields of winter
wheat and a considerable number of permanent pastures. From Chicago to
Omaha he will see only occasionally a field of wheat and scarcely any
permanent pasture. Oats have taken the place of wheat. In parts of
Eastern Kansas and Oklahoma the predominant crop is winter wheat.
Throughout the whole region from Pittsburg to Topeka, Kansas, the
characteristic crop is maize or Indian corn. Between St. Paul and
Fargo, the main crops are spring wheat and oats. One may travel from
Winnipeg, Manitoba, to Calgary, Alberta, a distance of over one
thousand miles without seeing a field of maize. In some portions the
main crop is wheat, in others it is oats.

These are illustrations of the crop adaptation over large areas, which
has come about unconsciously, as has most crop adaptation. In other
parts of the United States are to be found even more striking examples
of crop adaptation, although the areas are much smaller, as in the
case of tobacco, potatoes, celery, onions, apples, peaches and other
fruits. Regions containing residual soils are more variable in crop
adaptation than drift soils and require more careful watchfulness on
the part of those who may wish to buy land.

As previously stated, advantages, if known, must usually be paid for.
It comes about, therefore, that if a region or a farm is adapted to
the raising of a certain crop which is more profitable than the
average, such as maize, tobacco, alfalfa, celery, apples or peaches,
this land will, other things being equal, command a higher price than
land which does not possess this character
