the least average amount of repair. Up to thepresent that is the V-shaped wooden flume, but it is perhaps not aflight of fancy to predict that it is only a question of time whenstrong and light sectional metal flumes, semicircular in form, thatcan be quickly taken apart and transported from one point to anotherand put together and set up again, will be in common use. Metalsemicircular conduits, made in sections and easily put together, havealready been used in hydroelectric and irrigation projects. There is a conduit of this character in operation on the Sierra Na-tional Forest in California, and the writer sees no reason why a similartype of metal conduit, lighter in construction and somewhat modifiedin form, could not be developed for log or lumber flumes. The initialcost of construction would, of course, be considerably greater than fora wooden flume, but the metal one would have much greater dura-bility and length of service. BULLETIN 87, U. S.

FLUMES AND FLUMING. The wooden vshape flume. The V-shaped flume is at present the type of flume most generallyused in the western portion of the United States, and it has given themost general satisfaction for the transportation of manufacturedlumber or timber in its different forms of logs, railroad crossties,cordwood, etc. Some of these flumes have been in successful opera-tion for a number of years, and the writer, who has personally exam-ined many of them, has no hesitancy in saying that, if he were to con-struct a flume, the V-shaped flume is the type he would erect. Some of the salient points in which the V-shaped flume excelsare: (1) It can be successfully operated with a less volume of waterthan any other type, since, owing to the V form of construction,the water is always held confined or compact, and therefore hasthe greatest carrying power for the amount used. (2) There is less likelihood of jams forming, since the narrownessof the flume prevents the material from getting p
