Themeeting closed with a rising vote of thanks to the speaker. ♦-♦* PROTECTING RAILWAY MOTOR FIELD TERMINALS An effective and original method to prevent the burningout of fields, due to flashing at the terminals on account ofthe accumulation of carbon and copper dust, is being followedwith success by the Colorado Springs & Interurban RailwayCompany, of Colorado Springs, Colo. This method orig-inated about a year ago with B. M. Lathrop, superintendentof the company, and since its adoption has prevented the lossof a single field by lightning or otherwise. It consists first of making a mixture in equal parts of. PROTECTING THE LOWER FIELD TERMINALS OF A G ENO. 67 MOTOR shredded asbestos, shellac and plaster of paris, which, whenproperly introduced and kneaded, forms a pulp about equalin consistency to putty. The terminal posts and cables arethen thoroughly cleaned and fastened, and the mixture ap-plied so that it completely covers from view the entire con-nection. The shreds of the asbestos then serve to bind andhold the mixture together in drying after being applied and subjected to the air for abouttwenty-four hours, this mixture hardens by reason ofthe presence of the plaster of paris and shellac, andwith the asbestos forms a very tough and solid mater-ial. It can lie removed, if necessary, only by being brokenby severe hammering. 19$ STREET RAILWAY JOURNAL. [Vol. XXVII. No. 10.
