. Electrical world. d also the Brookline and Sub-urban Companies in that city laid considerable lengths of under-ground conduits, the Springfield system and the five Edison plantswere the only ones in Massachusetts that maintained more thantrifling lengths of electric light conductors underground. It thusappears that, with the single exception of the Springfield system, theEdison plants were more than a decade ahead of all others in theState in the construction of underground circuits. Of course, a ready explanation of the priority of the Edison plantsin underground work rests partly on the low voltage of 250 to 300,which has been maintained from first to last between the outsideconductors of their three-wire distribution systems. This explana-tion brings out more clearly the enterprise of the managers of theSpringfield system, in which alternating current of 1,000 volts wasdistributed through an extensive set of underground cables duringseven or eight years before any successful attempt on a large scale. J —T-NDERGROUND CONDUITS, SPRINGFIELD, MASS. was made elsewhere in the State to operate underground circuitsof more than 300 volts. The figures for underground conductors in the electric lightingsystems of Massachusetts on June 30, 1894, are interesting on thispoint. Aside from the five Edison systems above considered, theonly lighting plants with underground wires in the State, and thelengths of these wires, were the Springfield with 67,272 ft., theBrookline with 1,000 ft., the Pittsfield with ft., the Great Bar-rington with 450 ft., and the Winchendon with igS ft. Since June 30, 1895, when the Boston Electric Light Company had387,806 ft., the Suburban company, of Boston, 9,656 ft., and theBrookline company 14,872 ft. of wire underground, the installationof underground conduits and cables has gone rapidly forward insome cities of Massachusetts. During the following year the BostonElectric Light Company increased its length of underground wiresto 942,582 ft
