Such an insula-tor will carry 10,000 to 12,000 pounds stress with perfect safety. When in place, allterminal and clamp connectors and Johns insulators arecarefully taped and painted over with asphaltum. The trolley construction is very neat in appearance,and has been highly complimented by experts familiarwith the best current practice. ( To be continued.) Street Railway Engineers— james f. Mclaughlin James F. James F. McLaughlin, of Philadelphia, has earneda high reputation as an inventor and street railway engi-neer. He is only 31 years of age, but for several years hehas been well known in the electrical field. He was bornin Philadelphia of Scotch parents. When he was eightyears of age his parents died, and he was thrown on hisown resources. He attained a position as a district tele-graph messenger, and, as he was industrious, he was pro-moted from time to time, and became a skillfuloperator. Subsequently he was engaged as lineman andwas constantly employed in construction work. Duringall this time he devoted his leisure hours to study, and hegained a thorough acquaintancewith electrical theories while hewas increasing his practical ex-perience. In 1878 he accepteda position with the Bell Telephone Company, in Philadel-phia, and soon after made anextensive series of experimentswith telephonic apparatus, lead-ing to
