ughly sifted, we might get a bettertruck than we now have, if we could get the good points together inshape. Mr. Paul Windsor, of the Boston Elevated Ry., said his companykept wheel records by placing a cyclometer on the axle. Mr. Whitcomb, of the Composite Brake Shoe Co., believed it wasvery important to decide upon a standard form of brake shoe. Mr. Farrington added that he believed in bolting the brake shoedirect to the truck beam, doing away with a key and brake head. Mr. Conway, of Brockton, had used a number of maximum trac-tion trucks and had no trouble with them at speeds up to 15 milesan hour. He was greatly in favor of a center beaming truck fordouble trucks- Mr. Bradford, of Worcester, did not agree with Mr. Farringtonas to brake shoes, but thought the key and brake head should beretained. It was then voted to appoint a committee to prepare specifica-tions for a standard wheel, and decide what is the best weight,size, width of tread, and depth of flange. The chair appointed

Heavy weights are constantly being brought to bear uponpairs of wheels, and in many cases these weights amount to a con-siderable portion of the whole weight of the car. The truck should not only be equalized, but should have a swingmotion, with links (and I perfer spring links) as well as other setsof springs, which take up the first shock of the wheels upon tharails, but also other springs being composed of half elliptic, whichwill give the car an easy slow acting motion, together with helicalsprings, which will take care of the little humps. The equalization, or in other words, the distribution of the loadupon the wheels, should be perfect, and no opportunity be given foea wheel to jump at a moment when the load is removed, as thereshould be no leverage against the springs. This constant and even distribution of weight should
