the cadmium-copper wire and 130 days service of the replaced copper wire. Themaximum wear on the cadmium-copper wire was 40 milsand on the replaced copper wire 20 mils, the averagesbeing 30 and 12 mils respectively.

Tests of tensile strength,elongation and conductivity are given in the accompany-ing table. These tests were made by McGill University.The results indicate that the tensile strength of thecadmium-copper wire is from 6 to 9 per cent higherthan that of hard-drawn copper and the conductivity is34 to 4i per cent lower. Electric Tower Wagon
Text Appearing After Image:
Electric Truck Fitted as Tower Wagon THE accompanying illustration shows an Orwell elec-tric truck fitted as tower wagon which is used bythe Johannesburg, South Africa, municipality for elec-tric railway work. The speed of this truck is about20 m.p.h. and it has an operating range of about 50miles. The distance which can be operated per chargehas been sacrificed for speed, as the truck can be re-charged whenever it is not in actual service. Thistruck is being tried somewhat in the nature of anexperiment, as the municipality now uses gasoline-driven trucks, and if it proves entirely satisfactory itis contemplated to buy other electric trucks for thework. 278 Electric Railway Journal Vol. 58, No. 8 Convenient Forms for Recording Inspection and Overhauling Work Car House BLANK COMPAN DAILY INSPECTION SHEET Dm 2 if ( hi Ml !j 1 rs a1 i1 i £ i I J J r BLANK COMPANY WHEEL CHANGERS REPORT BUFFALO REMOVED APPLIED Th»l No. Ccit No. VLrel N«.
