This second well wascontinued to a depth of 250 feet, at which depth a feeble flow of muddy water washad. The flow was so small and the water so impregnated with sand and mud as tobe valueless, so the flow was cased off and the well was continued through very hardrock to a depth of 450 feet, then passed successively through clay, lava, and slate, andstopped at 700 feet in a stratum of dead, dry-looking clay. This well was withoutresult, although but for lack of funds it could have been bored much deeper. With the above data before us, and knowing that two attempts had been made inYoakum to get artesian water (with drop drills), both of which failed at about 600. 410 BLACK AND GEAND PKAIRIES, TEXAS. feet because the casing had been reduced to so small a size as to preclude reaching agreater depth with drop drills, we determined to make another effort for artesianwater. We employed Charles Karsch, who bored the wells at Hallettsville andiShiner and who works with the appliances of the American Well Works, a rotaryhydraulic system. The two previous attempts to bore artesian wells in Yoakum were made on anelevation 20 feet higher than our plant. In one of the wells, it was claimed, waterrose within 19 feet of the surface. Our present attempt is being made between twosurface wells which now supply through the medium of steam force pumps alltin water used through the waterworks system here, about 100,000 gallons perday. At 100 feet we passed through a rock and struck 8 feet of water sand, thewater rising up to a level with the water vein in the surface wells,
