depth of 6 0 0 feet* and a flow of 3§> million gallons of water per day secured from this well. Sow, the two springs and the Big Well sup­plied the city for a number of years* until 1942 when the second influx of workmen commenced* These were needed in order to build the large Basis Magnesium plant which produced a light strong metal from which airplane parts and inoendlary bomb® are aadej some 14*000 men were employed on this project, which cost in the neighborhood of 164,000,000. In order to supply all these men with water it was necessary to build a battery of 10 wells fro® which over 13*000,000 gallons of water can be produced each day. An ’•Artesian* well means one from which the water flows naturally, without assistance from mankind* This is made possible by the water entering an imper­vious strata from a point high in the mountains, and being confined in this channel until it is Happed* by a well* The water then rises until it attains an outlet and thus we have an artesian flow. However, as more and more wells are drilled, this has a tendency to decrease the flow and In such instances a pump is installed in the well to assist the water in rising to the top* The temperature here in the desert sometimes reaches 120 degrees In July and August, and of course, a great deal more water is required than in moist, cool climates* The per capita consumption here in those months has reached 640 gallons daily, which is about four times the national average* Trusting you will be able to gain some interest for your glass from the above information, I am, Very truly yours, LAS VEGAS LAND & WATER 00.
