escaping waste water.
On the east side the ridge broadens out
northward and has beau cut into by the
: river until vertical cliff of considerable
height has been formed. Against this
cliff the force OF the flow for two miles
above comes squarely, and being broken
by the solid hill, turns gently toward the
dam few hundred feet below. This
conformation gives additional security to
/ the dam, as no rush OF water, however
sudden or great, can reach it with per-
cedtible fe force.
The lake or reservoir formed by the
dam is seven miles, long, one mile and
three-quarters wide and holds about L.

supply the ditch with full head fox
Rff5Ay one 96Rp exaafaa}t xaafaa}tft twenty 'if feet above-the
bottom of the cut through whiefrthe main
canal is fed, and thirteen feet above the
feed-gates when open.
The main canal, leading from the rock
cut outlet heretofore described as near the
east end of the dam, is forty feet wide at
the bottom, seventy-fve at the top, has a
slope of one and half to one, and will
carry, through this great excavation, a
volume of water seven feet in depth.
Where gentle slopes or extensive flats Of
rocky, barren and worthless ground occur
on the inland, or upper side of the canal,
the enbankment is thrown up wholly on
the lower side, so as to utilize these flats
water. The main canal of the dimen-
sions stated, continues three and two
tenth miles down the river, when it is
divided into two smaller canals, one
branch going down on the esst and the
other on the west side Of the river. Now
let us follow the western branch of this
superb artificial water. way, and that is
the most important.
Owing to the considerable but uniform
descent of the river, the bottom of the
great hume across it is forty feet above
the river bed at the point OF crossing,
thus placing it far above the reach Of any
possible flood. The flume is reached by
"terre- plen" or raised earthwork, 1920
feet long across the river bottom, ITO feet
wide at the base and sixty feet on top,
through which runs the canal, twenty-five
feet wide at the bottom, with banks
sloping two to one and ofsufiicient height
to carry with safety seven feet of water.
The hume itself is twenty feet wide in
the clear, eight feet deep, 475 feet long
and rests on substantial trestlework with
spans sixteen feet in length. Another
'fterre-plein," 300 feet long. but otherwise
of the same dimensions as the one de-
scribed, conducts the water from the
fume to the high land on the west side
of the river, from whence it flows, seven
feet in depth, through ditch twenty-five
feet wide at the bottom and with high
banks sloping one and one.half to one.
The ditch passes about mile and hall
west of Eddy, meanders along the higher
portion of the valley from eight to ten
miles back from the river, and is com
pleted for distance of about thirty miles
