Pump Irrigation.

This is a subject of great interest here at the present and is being much discussed. Undoubtedly this method of irrigation will be widely used in Arizona before many years. It is es- pecially desirable in the vicinity of towns, for market gardening and fruit culture, where the value of the crop raised will justify expensive meth ods of cultivation, although the i'm prOvements in steam pumps designed for this purpose, which the growth of irrigation has stimulated, has resulted in obtaining increased capacity with diminished consumption of fuel. The successful employment of steam pumps Is only dependent upon the supply of water and cost of fuel. A pump of q capacity of 30 gallons a minute will be sufficient to cover two acres of land an inch deep every day, or IA acres once a week. A pump of this capacity with two horse power-engine and boil CT, costs in San Francisco or the east but little more than $200. Pumps of three or four times this capacity would be more desirable in this vicin- ity, and the general opinion is that the water supply to be obtained from wells along Pinal creek is ample to irrigate all the lands in this valley likely to be cultivated.
 The only attempt yet made here to test the practicability of the use of steam to raise water for irrigation was by Adolph Haag, who has a plat of about two acres of fine land at the southern end of town, set in grape vines and fruit trees. Last spring he obtained here boiler of 10 to l2 horse power with the necessary pipe, and sent to Van Duseu & lift, Cincinnati, for steam jet pump of 5000 gallons per hour capacity. The attachment cost, laid down here, $50, and the whole plant set up represents an out lay of about $260, the boiler and pipes being second hand. The design of the pump is most ingenious, and works on the principle of a syphon. Steam is forced down + inch pipe, through the pump attachment (the mechanism l of which we cannot describe, but which is said to be made on the principle oi globe valve) and into 21 inch dis charge pipe, the effect of which is to cause vacuum, and the water rises | and continues to flow in steady stream, without the least remittent action. One of the greatest advantag es of this is that the steam, constantly condensing in the water as 1t rises warns it slightly, so that it does not require to be run into tanks or reser voirs in order to bring it up to the temperature of the air, before applying it to the land that Is to be irrigated The saving thus affected is an import ant item.
 Mir Hasg informs us that the oper alton of the pump is all that is claim ed for it, but owing to the dIouth O last summer, he was unable to obtair a sufficient supply of water from hi well, and his vines and trees suffered somewhat. The effect of liberal irriga tion is shown by the rank growth O vines only few feet from a woodel tank which leaks slightly and kep the ground moist all summer. Thes vines are vigorous and at least thre times the size of others which wer deprived of sufficient water Nil Haag is now engaged in sinking deep CT two wells, about 30 or 40 feet apart which he will connect by tunnel an, hopes by this means to secure an abund snce of the vitalizing hquid.-Silve
