Opposite the power house, placed 70 ft. apart, are twosteel sections, 15 ft. long, from which steel penstocks, 66 in. indiameter, lead to the turbines in the power house. Figs. 5. 6 and The bottoms of the two canals are on the same level, but it is esti-mated that a difference of head of one foot will produce a flowthrough the pipe of about 320 cu. ft. per second.

Since these photographs were taken the pressure pipes covered with earth and the horizontal portions are protectedfrom the weather by a wooden sheathing. By means of this arrangement of pipes water f6r the turbines maybe drawn from either canal, or during the irrigation season, if either?canal should break through a retaining wall in the canyon, as some- FIG. 3.—ENTRANCE TO EAST INTAKE AND GATE.
