fiowaga line OF which Is 81: feet above
datum The Two reservoirs Will DE con-
nected by a thirty-s.x inch main about one
mile in length and the water flowing from
the higher TO the lower reservoir will gen
crate about 80 horse power. before 1t en-
tiers the low service distributing system.
hydraulic power plant Will be erected

to be excavated on the north side OF said
pipe Inc. The length of this channel will
De about 1900 feet and the bottom width will
be 100 feet. with such slopes as may be
necessary 20 prevent the sides from caviug.
Across the outlet OF Swan lake al earthea
dam is proposed. having a finished top
width OF about twenty :eet and slopes OF
two horizontal TO one vertical.
It is provided in the specifications that
whenever the city engineer shall desire
TO make tests OF the quality of the ma
teriais to be used in the construction. the
