The work of excavating for the foundations was begun Septem-ber I, 1897, the total excavation being about 35,000 cu. yds. Thefloor level of the station was fixed at i ft. above the high water markof 1884, in order that floods might not interfere with the operationof the plant. The intake pipe must be always under water in ordernot to lose the vacuum; accordingly, it was laid in a trench 13 ft.below the normal river level and over 40 ft. below the surface level.The trench for the intake pipe was over 300 ft. long, extendingnearly to the center of the river; the pipe itself is 60 in. in diameter,•ind is surrounded with concrete to make it permanent and give agood foundation for the machinery above it.
