Special devices had to be designed for splicing cablesand for the various kinds of connections that had to bemade to them. Owing to the nature of the soil, whichconsists largely of water, the setting of poles was attended with unusual difficulty and expense. All the poles are seteight feet in the ground, and in concrete. From one tothe other there are some twenty guy stubs at pointswhere there are turns in the line, or where the strain of abranch lead has to be balanced. The entire length of thetrunk line up Market to Felicity, thence to Dryades, thenceto Canal Street, is about two and a half miles. As oneline after another is passed the entire weight of copper is,of course, gradually diminished. The amount of copper 60 ft. from Pole.

Two of the former go onthrough to Esplanade Street on a similarly constructedline of forty and forty-five foot poles, this extension beingabout seven-eighths of a mile long. The return circuit of any one of the railway lines isentirely through the rails up to the intersection of thetrunk line, whence the track feeders, carried on the top ofthe arms of the trunk line, complete the return to the sta-tion. The tracks are all double bonded with No. o copper,except in some outlying portions of the lines, wherethey are single bonded. The Peters Avenue line is treblebonded from Canal Street to its intersection with thefeeder trunk line, as it is obliged to carry the returnfrom the Canal Street line as well as its own. All thelines above Canal Street intersect the trunk line at pointsnot greatly dista
