estimate and In the absence of ex

the required pipe line $4,000 feet
The difference in elevation between
the above two points is given as al
least IT'S feet.
This is case of pumping from q
well into storage reservoir near the
well and leading pipe down 3.E
miles to the village from the reser-
voir. The present well could not be
used as 1t is too near the house, not
allowing enough room for lot and
station building. 1t furthermore runs
down some 900 feet and encounters a
flow of warm water at the 72O feet
level which showed evidence OF oil.

lava rock and In lava boulders. It's
temperature is about so degrees or
81 degrees F. at this level. Anoth-
er well would have to be driven
down to the so IT. Cold water bear

one (1) acre obtained for we'll, sta

DR.. Swan, the owner Of the proper
ty, on which the present we'll Is driv-
en-, offers to sell the present well for
$4,000 and will allow the town one
year Of use before payment, the in
terest charge to be per cent. He
has no deed or title to the land at
present but will lease the ground re-
quired until such time as a deed can
be executed. He will also lease one
acre below the house for reservoir
for $500, the deed to be
executed as soon as he secures final
title to the land, or he offers to
lease one acre near the house for
new well, station building and reser-
voir for 5000, the deed to be execut-
ed as soon as he secures title to the i
land. This latter plan would be the
most feasible one and the well would
have to be driven above or on a
line with the present well in order to
be sure that its flow would in no way
be affected by future use of the pres
ent well.

water barrel must be at least inch |

friction loss. The best modern prac-
Ice in air lift pumping is to place
he air pipe outside Of the water bal
'el and inside OF the well casing. In
his way the compressed air, admit
ed through the inch pipe at the
proper depth, acts directly upon the
water column and is not broken up
