The investigation of the western soils,

tricts of California, Washington and
Montana, the Yellowstone valley, the Red
river valley and also the Mojave and Ne
yada deserts have developed some most
astounding facts and some which the de-

Professor Whitney says the history OF
these soils will make the most remarkable
chapter of the worlds agriculture. Al

er and desert districts mentioned, have
only one fifth to one-half of the annual

all the rainfall they receive comes i'll the

Only slight fraction falls during the

Investigation of these far western soils has
shown that they are largely made up of
the disintegm ton of the original basaltic
rock, and that there is little difference
between the soils and sub-Soils, a differ

remarkable power for absorption of moist

Thus the crops, by subsisting ON the
winter rains can stand long periods of
drought In the San Joaquin valley, the
great grape growing region of California,
the annual rainfall is but seven inches
and from May to September only about
six tenths of an inch falls, yet the vines
flourish throughout the season. 1t is true
they are irrigated by canals, but the mos
ture is absorbed and transmitted by the
soils. There is no surface application of
water. In southern California the winter
rainfall is about l6 inches, the summer
rainfall less than one inch, and without
irrigation tobacco and other crops grow
luXmiantly. At Chico, in this district,
sugar beets, which require great
amount of moisture, grow famously The

In the districts about Milton. Wala
Nalla, the Big Bend and Pullman by the
department termed the Palouse district,
the annual rainfall varies from 10 to 20
inches, in which from one to 10 inches fall
during the season of the growing crops.
yet owing to the wonderful power of the
soil to retain water and supply it to the
crops, a drought OF months is less iniuri-
