Thisportion was commenced, raised above the ordinary water-level,and provided with sluices through which the water was turnedwhen work was commenced on the other half. The com-mencement of the work was the bolting of three i 5-inch squaretimbers to the rock at the foot of the down-stream face (seeFig. 48). These timbers were level in the longitudinal direc-tion ; their upper faces were in line with each other and inclinedtransversely at the angle of the slope, viz., 2i|°. This formedthe starting-point of the work. The short transverse tim_berswere laid on, 6 feet apart, bolted t
