To make a flume projectfeasible, the stream should have a fairly even rate of fall and shouldcontain enough water to keep the flume full. The first flumes, put inover 6 or 8 years ago, were box flumes, with flat bottoms and straightsides. These answered very well for lumber, but it was found that cord-wood would jam in them and quite often force off the sides, thus cut-ting off all the water beyond the stoppage. This has been obviated byusing the Y-shaped flume, which causes the wood to be thrown out assoon as

This has been obviated byusing the Y-shaped flume, which causes the wood to be thrown out assoon as it jams, and thus prevents injury to the sides and allows thewater to go on down the flume. Practically all flumes in this regionare now constructed like this, and most box flumes have been convertedby putting the V inside the box. Flumes varying from 6 to 18miles in length are now being successfully operated at Nantahala, Cher-okee, Dillsboro, Addie, Swannanoa, and other points along the rail- N. C.
