The shunt A robs the relay ofmain line battery current very ma-terially, so that it responds to thehome key sluggishly. Consequently the auxiliary battery F is inserted in shunt 2. When thearmature C falls back this battery acts upon the magnetsand assists their prompt response to the home key or to anyother operator to such an extent that the shunt;.A does notcause noticeable drag. No matter what the line static maybe these shunts pacify the instruments and the static isnot felt. The armature spring is adjusted high enough to overcomethe wave of static that escapes A and B shunts. The aid. OVERHEAD BRACKET CONSTRUCTION MAIN LINE AND SIDING AT WESTHENRIETTA STATION jointly by the Western Union Telegraph Company and thetelegraph department of the railroad company. The order was given to the engineers on June 6, 1906,and although the intense activity in construction work allover the country at that time rendered it difficult to securematerials and labor promptly, the work was pushed so rap-idly that about seven and one-half months later, on Jan. 22,1907, the first official trial trip was run between Avon andRochester. The severe winter weather thereafter prevail- » 664 STREET RAILWAY JOURNAL. [Vol. XXX. No. 15. ing delayed the completion of the work until spring. Dur-ing April and May the whole equipment of sub-station ap-paratus, lines and cars was thoroughly tried out in a courseof experimental operation, which also enabled the railroademployees to become familiar with the new system. OnJune 18 commercial operation began and has since cont
