EXACTING REQUIREMENTS MET BY WOODEN FLUME
A wooden flume was recently built to conform to conditions that had been considered by some as being impossible of execution. The flume, which was elliptical in section with the bottom forming a curve of about 10-foot radius and the sides one of 6-foot radius, was constructed on a curve of 100-foot radius. The length of the section was 200 feet, and after 100 feet of the flume had been laid, the thickness of the staves was reduced from 2-1/4 inches to 1-1/16 inches, requiring a very difficult joint to be made. The principal staves of this flume were made of carefully selected kiln-dried Douglas fir.
