Until this altera-tion in the decision of the municipality is arrived at it is unlikely that the electric tramway systems will be ex-tended through the principal internal streets of the city. TRACTICE The early method of constructing horse tramway 1 racksin Buenos Ayres iias been primitive in the rails of heavy weight, but of very bad running sec-tion and external section, have been universally adopted,the sections used by almost all the companies being of thetwo types shown in Fig. 1, weighing 103 lbs. and 75 per yard. These rails were laid direct uponthe road without any foundation, either of cross ties orconcrete, with the result, after a very short time of run-ning, that may be easily imagined. In the reconstructionof the tramways for electrical purposes Fig. 2 shows the. FIG. 2.—NEW ELECTRIC RAILWAY SECTIONS IN BUENOS AYRES section of rails now being adopted of from 85 lbs. to 87lbs, per yard run in weight. These rails are being laidin three ways. Fig. 3 shows them laid upon a concretebase extending the whole width of the track; Fig. 5 showsthem laid on longitudinal concrete sleepers, one undereach rail, and Fig. 4 shows the rail laid on cross ties ofhard native wood called quebracho, the cross ties them-selves being supported on a foundation of broken brick orstone. These three forms of road-bed are used respectivelyin different parts of the city according to the wheel trafficwhich predominates therein. The rails, supported on acomplete concrete base, are used in the business center:those on the longitudinal concrete sleepers toward theoutskirts, and those on cross ties in the suburbs, wherethe traffic is lightest. The space between the rails ispaved with either wood, asphalt, stone sets, or macadam,as shown in the il
