1 6 TOWERS AND TANKS FOR WATER-WORKS. 



Atlantic City, N. J. About Sept. 12, 1889, 25X132-^. steel 

 stand-pipe when partly full was considerably damaged by wind 

 blowing at an estimated velocity of 100 miles per hour. The 

 pipe was constructed in 1883. In addition to indentation at 

 top, the tank rocked upon its base, raising several inches on 

 the windward side. There were no leaks and the tank has 

 continued in service. (Abstract Engineering News, Nov. 12, 

 1896.) Kenneth Allen, C.E., Atlantic City, N. J. 



Waco, Texas, Oct. 6, 1898. Stand-pipe, iron, 20X88, failed 

 when full of water and in service. According to the superin- 

 tendent, the general impression exists that the pipe was mali- 

 ciously blown up by dynamite. (Engineering News, Oct. 20, 

 1898.) J. P. Sample, Sec., Waco, Texas. 



Fairhaven, Mass., Nov. 9, 1901. This elevated water-tank 

 is particularly notable because the tank was one of the first with 

 a curved bottom ever erected in this country and one of the largest 

 of the type built to this time. The tank was 35 feet in diameter 

 and 50 feet high, with inverted cone bottom for two courses, chang- 

 ing to spherical form for inlet plate. Depth of cone about 12 feet. 



The plate of the tank at its connection with circular girder 

 flange was J inch, the second section was f inch, and the inlet 

 plate was \ inch thick. The tank was supported by twelve 

 inclined posts surmounted by a 3-ft. girder, from top of same to 

 foundations being 100 feet. Dressed-stone capstones rested 

 upon rubble masonry and were secured by two anchor bolts 

 for each column. The designing engineer was Mr. Freeman F. 

 Coffin, and the structure was built by the Messrs. Ritter-Connelly 

 Mfg. Co., of Pittsburgh, Pa. The tank-plate was originally 

 specified to be of iron, but was subsequently changed to sUvl, 

 which the manufacturers state was properly inspected and com- 

 plied with specifications for same. 



No subsequent tests of this material were made so far as 

 known, but it is generally agreed that the metal of the shell was 

 very good; that of the bottom fairly good, with one exa-plion;
