 The Canal. From the dam to tn forebay, measured on the line of th' canal, is a total distance of lO,OO feet Of this 5000 feet is canal proper, tn balance being in the reservoirs. Witt the exception of the lower 2,OOO feet the canal is largely excavated in rock
 Starting from the dam, the fiarini entrance of the canal is separated iron the east end of the dam by some 8 feet of solid rock ledge, the line O canal at this point being a continua ton of the easterly shore line of th' river. From here to the waste gates some $50 feet below, the canal rum through solid rock from IS to 40 fee deep, cutting off bend of the river ant encircling the river gorge. At thu waste gates the river is but short distance away the waste gates dis charging below Bulls Falls and direct. ly into the river, bed the gates them. selves being placed on a solid rock ledge with a steep pitch into the river below their outlet. The canal in the upper section has a bottom width of 25 feet and the side is more or less haring on account of the nature of the rock. A slope of one foot from the dam to the waste gates was given the bottom to accelerate the discharge of the river through the waste gates during con- struction. which at the lower end places it 2.3 feet below the true bottom of the canal, the change from one ele- vation to the other being made on a gradual slope.
 For distance of 200 feet 'above the waste gates the river bank of the canal was at a slightly lower elevation than the fiowage line. This was taken ad- vantage of to form a spillway. A masonry wall constructed with Port land cement mortar was laid on the river edge through this ,,200 feet with it's top at the elevation of the crest of the dam creating an automatic safety valve for the canal and aiding in the reduction of the flood level of the pond itself.
 A natural depression in the rock for nation at the site of the waste gates was taken advantage of to form the real entrance to the canal. An en- trance chamber was excavated in front of the waste gates and for a short dis tance below to receive the entrance gates. Between the entrance gates and the waste gates on the river side is an opening l6 feet iong in which travels a sliding gate whose top can be raised to the same elevation as the dam and which can be lowered some 2 feet, thus forming flush gate for the purpose of getting rid of ice and debris which may collect Tn front of the entrance gates. The canal from above the waste gates to the entrance gates is widened on gentle curves from 25 feet to 9S feet g inches making an easy flow for the cur rent without loss of head.
 From the entrance gates south dis tance of some 300 feet standard rock section of the canal is constructed be- ing 27.4 feet in width by 19.7 in depth. Through nearly this entire distance another spillway one foot higher than the dam was built as an additional pre- caution. At the lower end of this the canal crosses Bulls Bridge road and immediately below widens out into a section 40 feet in width with core. spending reduction in depth. From here for the next 400 feet the canal contains this wide section with an earth bank on the river side and with but comparatively small rock excava- tion. Thence into the first reservoir some 800 feet, thorough cut is made through hill, part earth and part rock, where the canal is changed again to normal rock section, its entrance into the porld being fiared to avoid loss of head.
 The reservoir is practically divided into two ponds by an earth fill con- structed to carry the main wagon road, the connection between the two ponds being under bridge no feetIlong with a section area of about 1000 square feet. The canal leaves the reservoir at it's southeast corner. the entrance be- ing hared as in the preceding cases. The standard section is Ethen used for some 300 feet where the canal again widens with corresponding reduction in depth. Thence for the next 1,700 feet the construction is substantially as last stated. Through this portion the canal being on the side hill, the lower side is formed by heavy earth embankment backed by the rock taken from the bot tom of the excavation, it being neces- sary, to get section area, to excavate
