FLUMES.
157
The logs, brush, and leaves from the lower bank (under the artificial bank) are carefully removed. The founda­tion is generally cut for the entire width of the flume. The sketch (Fig. 18) shows the method of posting along cliffs, where the foundation is occasionally narrower than the flume. Where flumes connect with the ditch, the posts of the flumes, for a distance of several boxes, are 4 to 4-1/2 high, allowing an additional side plank. The grade of the flume is 32 feet per mile. The planking is 2 inches thick.
