Excerpt from Contributions to the Hydrology of Eastern United States, 1904The California or stove-pipe Method of Well Construction, by Charle S. Slichter.In the larger number of the wells in the gravels, sands, etc., of the Coastal Plain regions of the Atlantic States and elsewhere, the hole is tightly cased throughout, the. Only point of entrance for the water being at the bottom. Onlv one water bed can be drawn upon in such wells. In California. And to some extent elsewhere, however, a method Is in use whereby, by means of casings perforated at intervals, water can enter the well at a number of different levels. The casing con sists of a steel shod starter, 15 to 25 feet long, and sections of steel pipe 2 feet in length overlapping with ¿ush joints. The casing is forced downward, length by length, by hydraulic jacks to the desired depth. In one well a depth of over feet has been reached. After the well has been forced to the required depth a cutting knife, two types of which are figured in the paper, is lowered and slits or holes are cut through the casing at the points where, according to the record, water is known to occur. As much as 400 feet of a 500-foot well may be perforated if the conditions demand it. The type of well described has many advantages in addition to that of rendering several sources of water simultaneously available, and will doubtless be of great value in many localities in the east when the waters at the differ ent levels are under similar heads.Approximate Methods of Measuring the Yield of Flowing Wells, by Charles S.
