Show WELL IN THE DESERT New Plants Are Centrifugal Pumps Run by Steam. Regions Which Had Never Been Forced by Drought to Seek Water and Having Found It They Will Now Use Irrigation. Sinking well Into waterbearing struta to secure domestic and Irrigation Irriga-tion supplies Is now being resorted to as never before. New and broad er conceptions of the relation of subterranean sub-terranean water to irrigation have recently prevailed. Individual Irrigation Irriga-tion undertaking have been recently established very largely upon wells nd pump or upon flowing well, wherever they can be had. During the last three year there have been perhaps per-haps ten time a muny pumping out-Ills out-Ills set up for Irrigation as had been employed during the whole earlier Irrigation Ir-rigation of thl state. Largo Irrigation compnnle have unk groups of wills and pumped from them Into their distributing jltche and flume. Individual irrigator irri-gator have sunk well and bought pumping plant when the ditch water fulled and bavo now learned tlie superiority su-periority of home supply, to be drawn ip just when It can be used to best idvuntage, and often to be had for 'tnuch lens than the rate of the ditch :ompunle. Largo region which had never secured Irrigation ystems have been forced by drought to seek water ind having found .It below ground In tuple quantities they will not fall In the future to use Irrigation as a sup pUment to the rainfall. Many of these plant are centrlfu lal pumps run by steam. Thce are Uie larger plant, fifteen to forty horsepower and In some Instances more, and the size of the pumps ranges !rom four to twelve Inche. Most of Iho smaller pumps are run by gasoline, gaso-line, although several use crude oil and many of them are also centrlfu fal. Some of these are deep-well pumps and they are very satlafac 'cry In raising water from a greater Jepth than 100 feet. From 100 to 300 Vet they work admirably. The cost 3f pumping differ materially with '.he different kinds of power, size of pump and depth of wells. FlgnTlng from what may be a aafe average of the actual cost of fuel, a No. 4 pump. :entrtfugal, ualng gasoline a power, it 70 feet depth, will cost about three dollars a day. This should result In S00 gallons a minute, 36,000 gallons an hour, or 360,000 gallons a day of ten hours. Kuch a stream of water la calculated calcu-lated to Irrigate about Ore acres a day lo a depth of a little more than 2 4 Inche. A better and safer estimate aould probably be four acres a day 'jo a depth of about two Inches. Hut, generally speaking. It Is safer to say :hat at a cost of three dollars an acre .and can be Irrigated two or three :1m'1 at six dollar an acre annually ind It I certainly worth the money n dry season like the present. The iverage cost of a plant Is about f 1,200 !n many cases the cost will be only a . 'ractlon of that given. Hut even the llgher figure are below the cost war- 'anted by the saving of a crop, a the , xprrlence of Individuals ha shown. )vr large aren of the country wind-nlll wind-nlll are UHcd.as motor for Irriga- Ion .pump and careful accounts of ( heir tfTlclency are available. They ( inquest lonably serve an excellent pur- ( ose under favorable conditions up to ha limit of their capacity. |
