Plata 1, Aj shows the meter case, which is 3 inches in inside diameter and 36 inches long, and beside it the meter, which is 3 inches outside diameter and about 6 inches long, also the winch with about 1,000 feet of 0.09-inch steel cable resting upon the box into which it folds for moving. On the and of the cable is hanging an assembly consisting of bushings from four inches down to the l/8-inch packing gland. Plate 1, B, shows the Sund well on the Lindsay Estate while the pipe fittings were being removed. Plate 1, C shows the same well under control and the test in progress.
