. The street railway review . as some question as to the best method to be employed for con-ducting the current. Both the third-rail and the overhead forms ofconstruction have their advantages and were considered. At thistime Mr. Elmer P. Morris, New York agent of the Electric Rail-way Equipment Co., of Cincinnati, agreed to erect about 1,000 an improved form of catenary construction which he had de-signed and on which tests could be made in an effort to determineihe practicability of a system of this kind. This form of catenaryconstruction is designed to be used on high-voltage systems ofelectric railways and Mr. Morris believed that its use in this in-stance would prove satisfactory. The test line was constructed at Reading, Pa., and the tests weremade on April 21st. The line consisted of two sections, respectively350 and 300 ft. in length, of catenary which were supported ontubular iron poles 48 ft. high. These poles, three in number, were10 in. in diameter at the bottom, 8 in. at the top. and were set in. Cl ERAL VIEW OF CATENARY C0NSTR1 CTIOK concrete to a depth of 7^ ft. The poles were guyed with Milleranchors, manufactured hy the Miller Anchor Co., Norwalk, anchors stood the severe test loads in a very satisfactorymanner. The tests were made on the middle pole, which was fittedup with the improved form of catenary support. This construc- tion coresponded as nearly as possible to that to be erected forordinary operating conditions. The catenary cable was composed of %-in. extra heavy Siemenssteel strand wire covered with triple braid weather-proof insulation,giving a cable with a diameter of approximately % in. The cablewas supported by a 2-in. tubular iron bracket 12 ft. long. The cable
