ARTISAN TELLS.

The question of supplying Arizona with Artesian water having engaged the attention of our people, and been made the subject of legal enactment as we'll as attracting the mo- tice of city government, we presume the following from the San Diego World will be interesting to our readers.
 "We give below some facts in regard to ar tesian wells, that may te interesting 10 our readers, especially since 1t IS proposed to in- augurate this description of wells not merely in San Diego county but wherever else it may be required. Artesan wells were first dug at Artos, in France, over one hundred years ago. They flew out of the ground at different heights, and we make this state ment merely because it has become fashiona- ble to call a well of small bore which does not flow, an arteslan we'll which is not cor rect, in any sense. To show something of the depth at which water is procured in these wells, we give the deepest only.

 The artesian well at Louisville, which we have seen, sends stream up into the air say twelve 10 fifteen feet. The we'll at St Louis, bored by Mr. Belcher for his sugar refinery, is cut of in its flow so as to serve the re- fnery, and at the same time water such peo- pie as fancy mineral water Its flow is constant, and the supply never ceasing, as is also the Louisville artesian. The well dug by the county of St. Louis, at the Insane A sylum, having a depth of ,, ,S43 feet does not, so far as we are informed, flow out, the we'll being failure, or abandoned before water was procured That we'll is below the level of the sea by three thousand feet. It is not likely such depths would be necessary in Cal itornia, and not often elsewhere.
 At the well in Sperenburg, near Berlin, the government, in order to obtain a supply of rock salt, began the sinking of the shaft lG feet in diameter. At depth of 260 feet salt was reached, but excavations were continued the diameter being reduced to l3 inches, for i, l94 feet, at which point work was discon- tinued, the bit still remaining in tue salt de- posit, which thus exhibits the pro6igous thickness of 3,910 feet of salt.
 The water pressure in the wells of St Louis and Louisville, would be about one thousand pounds to the square inch, which as stated, gives flow of about twelve or fifteen feet above the ground.
 At Aire, France, well, bored over a cen- tury ago, has since then flowed steadily, the water raising II feet above the surface at the rate of 250 gallons per minute and at Lilliers in the same country, one well has yielded continuous stream since the year ll25.
 Some seventy five shafts have been sunk on the Desert of Sahara, yeilding an aggre- pate of 6(D0 Q00 oollonS nor hour The effact of this supply is said to be plainly apparent upon the once barren soil of the desert. Two new villages have been built and l50,000 palm trees have been planted in more than 1000 new gardens.
 In Sahara, the depth to be. dug is said to be not over POO feet, when water is procured.
 We have no data as to the flow of the wells of lesser depth than here mentioned, and these are given more as a matter of inter- est to the curious than because of the aver age in depth, or the capacity of the well. It is likely the company here will procure such statistics"
