This is con-structed with profile iron and angle iron, so joined as toform an inverted U. The principal economical featureemphasized is that the conduit is in close proximity to oneof the track rails, which therefore serves as both the trackand slot rail. The slot is kept open and clean by the flangeof the car wheel. The profile iron and angle iron are firmlybraced by the rod attached to the further rail, as shownin Fig. 2.

The trolley wire itself is supported on ironbrackets by a holder very similar to that used on overheadsystems. It is stated that the conduit may be laid asrapidly as a system of water piping, except on curves andwhere special work is necessary. The inventors are nowworking out a complete system of crossings and drainage conduit is connected at short intervals bypipes to the local sewerage system. The trolley is flat and carries on its side a trolley arm. FIG. 2.—SECTION OF CONDUIT. capable of a limited universal motion, and is backed byspring pressure. The entrance of the conduit is curvedso as to admit the trolley without catching it uponsharp edges. In order to protect the ironwork from rust, the parts are dipped in hot tar before being put in place. The wholeconstruction, being rigidly bolted together, has greatstrength. The yokes will stand a vertical pressure of 5500pounds, and an equal lateral pressure has been applied tothe sides of the conduit without apparent injurious result. New Street Car Rail. The Metropolitan Traction Company has adopted a newrail, of the section shown in the accompanying was designed by Mr. John D. Crimmins, and is intendedto make the traffic of ordinary vehicles easier. With pre-vailing rail sections a broad, rectangular groove is madein the street, bounded on one side and the bottom by therail, and on the other side by the paving blocks. Thegauge of the t
