The discussion following the readingof the paper was rather limited, inas-much as this subject is new to the mem-bers of the association, this branch ofair brake business not having been as yet as thoroughly taken up and under-stood as the steam part has been. At this point Mr. J. F. Deems, gen-eral superintendent of motive power roll-ing stock and machinery on the Vander-bilt lines, addressed the in a happy vein, Mr. Deemsproceeded to the more scnous contem-plation of the work of the association, itspast performances and its future respon-sibilities. He believed this work to beone of the most important on railroads,since the stopping of trains has been leftentirely to the ai
