No money wliateverhas been spent in repairing this portion of liemerbe tramway, butthe adjoining portion of girder rail has been several times re-paired during the six years it has been laid down. The setts usedalongside the Demerbe rail are splayed to fit the sides of the rail,and laid directly against it, the rail thus serving as a supportfor the paving; and there is no tendency either for the setts torise or fall as is the case with the girder rail. There are in Brad-ford 40,,-i miles of tramways, of which ,?6,j miles are laid on thegirder system, with rails weighing 105 lb. per yd., and fishplatesweighing 80 lb. per p.iir.

A cross section through a joint is shown in Fig. i. The rail,A. is a hollow trough and the fishplate, B, exactly fits its interiorcontour. When this system w^as first introduced the fishplate waspressed into the rail by means of bolts, but it was soon found thatthis was not satisfactory, and cotters, E, were used. .\s the holesin the fishplates and rails are cut at diflferent depths, when thecotters are driven in the fishplate is forced close up to the under-side of the rail. The ends of the cotters are then clinched againstthe side of the rail, and are thus fixed and prevented by any pos-sibility from working loose. The rail when laid in position in thecarriageway is completely filled, by means of specially designedtools, with concrete, composed of four parts of H in. uncreened granite shingle to one part of portland cement.
