As to the bodyframing, the corner posts are of yellow pine %y2 in. x3% in., made in two pieces; the side posts are 1 by 1% in. maximum width and the continuous-type carlines are formed of steel 1% in. deep and 3 bolted to side pieces and wooden carlines.

Ventilation isobtained by means of Garland ventilators, two per operating equipment of each car includes twoGE-219 motors rated at 40 hp each, K-36 control andSt. Louis vertical wheel brakes. PROPOSED SELKIRK TUNNEL AND ELECTRIFICATION Plans for the boring and ultimate electrification ofa five-mile, double-track cut-off tunnel through the Sel-kirk Mountains in British Columbia are being consid-ered by the Canadian Pacific Railroad. The bore of thetunnel will be 17 ft., and the grades encountered willreach about 2 per cent. It is expected that the tunnelwill be approached by an electrified section of 7 miles ofdouble track and that the third-rail 2400-volt sys-tem will be employed. Power will probably be suppliedfrom a future power station to be installed near theelectrification, rather than by undergoing the greatexpense of erecting a long transmission line over
