Important Figures.

Mr.. II. B. Blowers, one of the pioneer
and most successful raisin growers of
California, in his address before the Irri.
gators Convention at Riverside gave the
following figures of the cost of lifting
water for irrigation. These figures are
very important and may be the means
of producing large water development
on what is now called desert land. The
readers of the HERALD will do well to
cut out these figures and preserve them
for future reference. They should be
carefully considered by the thousands of
persons who are investing in lands and
by those who have lands to sell, so that
an intelligent value can be set upon
land now known as dry land.
The plan adopted by Mr.. Blowers has
proved conplete success. His figures
and system of operations are as follows

To this calculation must be added loss

discharge is used. Care should be taken
to have both suction and discharge pipe
larger than bore of the pump, aud avoid
all angles possible in pipes.
My method of irrigating vines by
pump: | first plow from the vines then
run water down the rows, adding to the
rainfall about ten inches. This com.
pleted the winter Irrigation. Then plow
towards the vine cultivating thoroughly
during the spring. In June, after the
grapes have set and are as large us peas,
| run furrow down and back in the
ceAter OF the rows with narrow plow,
thus making a deep narrow trench. |
