tration shows a meat box motor car.The boxes are 5 ft. 11 ins. square outside and 7 ft. 3 ins. high.They have double sides and are lined with zinc. There are slatventilators in the two sides and in the doors. The latter lift up-ward into a horizontal position when open. To economize spacein front that part of the side which is below the door lifts out, in-stead of being made to swing. Inside the boxes are fitted withpipe racks in the center, along the sides, and stationary racks inthe roof, all of which are provided with sliding hooks for meat. In some cases the boxes are carried on flat trail-cars. In thiscase each corner of the box is furnished with a heavy iron strapterminating at the top in a strong eye.

Hespoke undoubtedly with a full realization of what the statementmeant, for none but the actual workers in the field in the earlydays of electric railroading can understand the utter discourage-ment that came withlhe use of wire brushes, particularly for mo-tors, but also to a large extent for railway generators. Often acommutator would be completely rutted and a wire brush chewedup in a half days run of a car, and the operator was fortunate ifa burned out armature was not also the result. Electric motors inrailway work were at one time actually on the edge of failurethrough this one imperfect feature. The carbon brush entirelychanged the complexion of affairs. Sparking was almost com-pletely done away with, both
