Mr. RossE. Browne, hydraulicengineer of San Francisco, who has tested this -wheel, reports an etfi-cieney of 82-6 [)er cent, under 5()-ft. head, with a 15-in. whetd, and says that the velocity ofthe bucket should be one half that of the jet. Other tests of a fi-ft. wheel, by Messrs. Ed-ward Coleman and George Fletcher, in 1884. showed au cliiciencv of 87 per cent. In this casethe velocity of bucket as compared to the theoretical velocity of jet was about 53 per cent. The great simplicity and economy of construction of tiiis wheel commends it to atten-tion, and it is especially available for veri/ hiyh heads and very snudl volumes of water. Inthe last test quoted, the head of water was ;i80 ft., the diameter of pipe, 22 in., and thediameter of nozzle thro
