estimable value to ranchers and re
Chalmers in Nevada has Just been Is
sued by Charles A. Norcross Commis-
sioner' of Industry, Agriculture and
Irrigation. The book is ready for dis
tribution. having just LETT the press at
the State Printing Once.
The book takes up the science OF If
rigation by pumping from the start
and in a simple, practical manner ex-
plains the methods used, estimates the
cost and gives all data and informa-
ton needed to successfully pursue the
work. tsH 4t a}sa
In brief introduction Commission
err Norcross takes up the possibilities
and probable results to be obtained
from irrigation by the pumping sys-
TEN in Nevada. Oh the area OF arabic
valley lands in the State the introduc-
ton to the work says: 1
The total area Of arabic lands IN
Nevada, capable OF bountiful crop
Yields, where water for irrigation IS
obtainable, is not less than l8,0OO,0OO
acres. The total area now under cul-
tivation is about $4,000. acres, prac-
tically all reclaimed by means of sur
face waters. The flows of the streams

rigation season are appropriated. The
flood waters of the Truckee- Carson
system are controlled by the United
States reclamation service for conser
walton to supply the Fallon project
The food waters OF number OF other
streams are likewise appropriated by
private enterprise engaged IN, Or pro
posing the construction OF, storage
systems to impound the waters which
now flow to waste during the nonirrl-
CATION season. When all such feasible
storage of flood waters takes place, y
is yet not probable that the total area
of lands, which surface waters OF the
State can reclaim will exceed $780,
600 acres, or about 8 per cent OF the
total arabic lands"
The first part OF the book is devoted
to discussion in explanation OF yarl
Gus methods OF determining the water
supply, both where surface water and
subsurface water is to be pumped, de-
claring that the majority OF failures
connected with pumping plants for ir
rigation, especially in pumping sub
surface waters, are due to neglecting
to test out the inflow prior to install
ing the pump The problem OF esti-
mating the inflow of subsurface water
is dwelt on at length.
Every possible existing condition
involving the measurement OF water Is
gone into by the commissioner and the
first part OF his book forms an excel
leut basis. for the more important and
detailed discussion in connection with
different phases and points involved
that follow farther along in the vol
urne.s
The problem of the permanence of
the water supply is next taken up. In
Guided in this part is an explanation
of the various irrigation seasons in diff
ferent section of the State. Conditions
tending to increase and diminish the
flow at various seasons of the year are
exclaimed and the explanation of
methods used to get the best results
is given, the subject being dealt with
as it applies to surface and artesian
flows. =. -; ..

In a decision of the quantity of wa
ter required for irrigation the book
says: lA s9sl
under average conditions of SOIL
length or irrigation season ESQ days.,
q
water is the quantity commonly ac-
cepted as the basis OF water duty cal
culations in this State for lands in all
sections except the sub7tropical In
the latter extreme temperature and
longer irrigation period makes larger
quantity necessary "
"A constant flow of asa gallons per
minute will discharge three. acre-feet
of water in $50 days, the normal irriga-
ton season. Where water is pumped
for irrigation. the cost of pumping, be
ing ever present in the mind OF the
farmer. stimulates his conservation OF
it to maximum waterbury, Very lit
tie of it is wastefully or improvidently
used. Moreover. under such condi-
tons, irrigation occurs almost exclu
sively by the furrow method rather
than by flooding and small head,
which would have relatively small
duty by the flooded method, can show
much higher duty by the furrow
method. Nevertheless, low heads of

ton practices. exhibit a decreasing wa
