WESTERN IRRIGATION WORKS.

联邦政府的咨询工程师J. H. Quinton在谈到西方灌溉工程3500,000美元的拟议支出时说，西方的肤色将在政府完成其五个巨大项目时完全改变。其中，Gunnison隧道或Uncompaghre项目是最大的项目，在许多方面，类似于亚利桑那州的盐河系统，该系统包含了现在正在建造的Tonto大坝。它将在凤凰城附近灌溉盐河谷，该定居者非常需要水。在内华达州的项目中，特拉基河的水域被带到卡森河，为存储目的而建造了巨大的水库。该灌溉企业预计将提供20万英亩的干旱土地。在此连接中建造的主要运河实际上已经完成，并且将尽快让子公司的合同。另一个大型工作是爱达荷州的Minidoka项目，最近出租了该项目。这包括在蛇河上建造大坝和几个大水坝，以便在山上储存。他的项目还将灌溉约200,000英亩的实际干旱土地。新墨西哥州的本多项目将在一个极其生产的部分中灌溉约12,000英亩的罗斯威尔附近的有价值的土地。 Besides the above projects already begun by the government there arc several others in preparation, for all of which contracts will he let early next year. These are the Soshone project near Cody, Wyo., the Bellefourche project in South Dakota, and the Fort Buford project on the Yellowstone in North Dakota and Montana. There is still another undertaking which may be decided upon this winter, known as the Milk river project in Montana, which will open up a large section of country. As a result of the tests of the underflow in the Arkansas river valley, a site has been recommended for an infiltration gal lory in the neighborhood of Deerfield, Kan., at a point one and one-half miles above the head gates of the Farmer’s ditch. The operations begun in 1901 will be completed this month with the tests of a line of stations at Deerfield and in two locations at Hartford. The conditions at Deerfield have been found to lie the same as those nqar Garden City. I'hc average range of the velocities of the underflow near Hartford has proved to be from six to twenty four hours, and the general direction of the seepage is in an easterly direction corresponding to the slope of the valley. An infiltration gallery is only a very elongated surface well. It is a ditch or tunnel, with its bottom below the water tabic and running as nearly as possible at right angles to the direction of the underflow. In the bottom lands of the Arkansas valley water can lie pumped so cheaply that an infiltration gallery to provide water for such lands would he impracticable. At a point near Lakin and Hartland there is found the mouth of the disappearing stream known as Bear creek. I bis is a perennial stream that disappears as soon as it reaches the sand hills, five or ten miles south of the channel of the Arkansas. As to the possibilities of irrigation through the use of the underground supply: The system is more complicated and expensive than the common practice of using the perennial flow of surface streams. The appropriation of the flow of the rivers by the mountain stations has left the settlers along the valleys of the great plains entirely dependent upon the underground waters for irrigation.
