contact. The expansion of the air in the eduction pipe of the air lift
absorbs heat from the water and lowers its temperature. If the water
is naturally cold, the reduction will be slight, but if the temperature
of the water is high, the reduction
e
will be marked. This is a great
advantage in water to be used for
condensing purposes, as the reduc-
tion of a few degrees in the temper-
ature of the water will make a great
difference in the amount of coal used.
The air lift installation is more
durable, and requires less atten-
tion and repairs than any other
method of pumping. When once
the well or wells are properly
adjusted, the installation requires no
further attention. The water never
comes in contact with any moving
parts and the machinery is in the
power house directly under the eye of
the engineer, avoiding all pulling of
sucker rods, working barrels, et
cetera.
On account of the ease with which
installations may be made, it is only
in recent years that efficiency has
been thought of in connection with
air lift work.
As a rgeneral thing, manufacturers
have sold compressors for this work

tomer, without making a thorough
investigation of his requirements or

advising him as to the best method of developing his supply. It
has been so easy to turn the air loose in a well and get certain
results, and there has been so little known of the laws governing this
method of pumping, that haphazard installations have given it a
reputation for inefficiency that is not warranted, and which a careful
study of the subject will tend to remove.
When Dr. Pohlé worked out his theory of a submergence of sixty
per cent and of alternate plugs of air and water, he secured an efficiency
of from twenty to twenty-five per cent, which at that time was thought
to be as high as could be depended upon. Since then, experiments
