Bulletin No 203 The Distribu-
ton OF Water in the Soil in FurTow
Irrigation BY. r. II. Loughridge,
Phi. d., of the University of Cali
fornia. This bulletin contains the
results of observations upon the per-
collation. of water in the soil beneath
the burrows in which water is applied
TO orchards in the vicinity of River
side, Cal. These observations were
losses of irrigation water and their
prevention. In the vicinity of River
size the available water supply has
been put to use. and further expan-
sion of the irrigated area depends
upon more economical use OF this
supply. Canals have been lined to
prevent seepage losses. the orchards
are intensIyely cultivated to check
evaporation losses, and this study
was undertaken to arrive at some
knowledge as to the losses by per-
collation., with a view to taking steps {
to lessen them If practicable. 1t
does NOT, however, 90 into the ques-
tion of methods of checking these
losses. The report contains the re-
suits OF observations on number
of orchards. the results showing
clearly the great necessity of each
examining his own soil
and subsoil and adapting his meth
DDS 10 these conditions.
Bulletin No. 205. Irrigation in
BY c. 7. Johnston. State
Engineer. The great activity in the
construction of irrigation works
throughout the west by the govern

The Use of Small Water Supplies

hief of Irrigation Investigations. VI
his article discusses the possibili- III

rings and building small reser-

Losses of Irrigation Water and H

percolation beyond the reach OF
