The following is taken from Trautwine, and is a fair sample of his comprehensive and valuable method of treating all subjects. SIZES OF TANKS AND CONTENTS. Diam. Depth. Gallons. Diam. Depth. Gallons. | Ft. Ft. Ft. Ft. Cypress or any of the pines answer very well for tanks. The staves may be about 2% ins. thick for the smaller ones; to 4 or 5 ins for the largest. The bottoms may be the same. The staves should be planed by machinery to suit the curve precisely. Nothing is then needed between the staves to produce tightness. A single wooden dowel is inserted between each two near the top, merely to hold them in place while being put together. The bottom is dowelled together, and simply inserted into a groove very accurately cut, about an inch deep, around the inner circumference of the tub, at a few inches above the bottoms of the staves. One of 20 feet diameter, and 12 feet deep, may have 9 hoops of good iron, placed several inches nearer together at the bottom of the tank than at the top. Their width 3 inches; the thickness of the lower two, 94 inch; thence gradually diminishing until the top one is but half as thick. The lower two are driven close together. These dimensions will allow for the rivet-holes for riveting together the overlapping ends; and for a moderate strain in driving the hoops firmly into place. Three rivets of 3% inch diameter, and 3 inches apart, in line, are sufficient for a joint of a lower hoop. One of 34 feet diameter, 17 deep, may have 12 hoops; the lower ones 4 inches by 3%; with three 34 inch rivets to a lower hoop-joint. The bottom planks of the tank must bear firmly upon their supporting joists, or bearers. A tank must have a waste pipe for preventing overflow, and a discharge or feed pipe 7 or 8 inches diameter, in or near the bottom. The inner end of the discharge pipe is covered by a valve, to be opened at will by the engine man, by means of an outside cord and lever. To its outer end is generally attached a flexible canvas and gum-elastic hose about 7 or 8 inches diameter and 8 or 10 feet long, through which the water enters the tender-tank. Or, instead of a hose, the feed-pipe may be prolonged by a metallic pipe, or nozzle, sufficiently long to reach the tender; and so jointed as, when not in use, to swing to one side, or to be raised to a vertical position.
