TELPHERAGE. 



brackets it is protected b}- what are called "shields," these being' 

 arranged so that they can be readily replaced. The cable is also pro- 

 tected at the hanger and l)rackets b}^ steel shields. 



Capacity. — An important feature in telpherage is the capacity of 

 the line. In general, I can say that there is no other form of con- 

 vej'or known which shows such flexibility. This is due to the use of 

 electricity, and the features which apply to the street railway apply 

 also to telpherage. There are two factors of special importance in 

 relation to the capacity of the line: First, the speed, and second, the 

 number of telphers and trailers. The line may be laid out with one

telpher and a few trailers. More telphers or trailers may l)e added, 

 and, if upon a single line, coupled in long trains. If it is desired still 

 further to increase the capacity, the line may be made double, while, 

 if desii'cd, the carriers may also b<> made continuous so as to take 

 boxes and barrels or other freight as fast as they can l)e tlelivered to 

 th(> carriers of the telphers and trailers. 



The lle.xibiiity of telpherage in r(>gar(l lo capacity is wonderful, and 

 is a most im])()rtant Feature. In fact, it may ])e said that there is 

 practically no limit to (lexibility. In one plant, about to be installed,
