It would be still better to lay the pipe wholly or partly in a bed of concrete, as this can be tightly bonded with the earth. The pipe, of course, would be provided with suitable valves _for opening or closing the outlet. In regard to the flow which the Pumping Water for Irrigation. Mr. A. B. Fowler, of Guernsey, Wyon1ing, writes that he has a pumping plant belonging to Mr. E. F. Hurdle and himself, consisting of a second-hand 70horse power boiler and 50-horse power engine, costing $1,500 in place. The running expenses amount to $5 per day for labor and fuel. By means of it 7 cubic feet of water per second are raised to a height of 2o feet. This amount of water irrigates one acre per hour of crops planted in rows, and one-half an acre per hour when used in flooding. The pump is estimated to furnish suflicient water for 500 acres in diversified crops, but up to-the present the engine has not been operated for more than onethird of the time in any season, as yet only about 2oo acres of land being under cultivation. This device has been an unqualified success, and would be in any other similar locality where an abundance of water can be had.
