ELECTROLYSIS AT RICHMOND
Dabney H. Maury, who has recently been employed to examine into the condition of the water mains at Richmond, Va., reports that electroylsis is still working mischief among the pipes in the city. He states that, after making examinations of the street car rails at sixtv different points and fifty excavations he found that all the pipes so examined were found to be conductors of electric currents. The damage he reported as being rarely slight, often serious, and still going on. The estimated cost of the pipes is placed at $766,000, and the estimated depreciation in value, $170,224, or twenty-two and two-tenths per cent. This does not include incidental damage and risks (such as breakage of pipes in case of fire), and the report contends that the actual damage is incapable of being expressed in figures. It holds it, however, to be largely in excess of the $17,224. The report closes with a recital from the report of the electroylsis committee of the American Waterworks association in 1901, in which the single overhead trolley system is criticised, and the double system, and the conduit system praised—the double overhead system being preferred because less expensive.
