They mayobviate some of the disadvantages of the open slot conduit with thecontinuous wire; they may claim to possess certain advantages in theway of costs and other considerations which are even less apparentthan that ot cost, but they have other objections which, I think, putthem far behind any open slot conduit system, although I do not mean.

But let us return to the open slot conduit systems that have beentried and installed. What do we find? We find, in the first place, avery small conduit poorly constructed. The wires are located in verypoor positions and badly protected. The drainage is exceedingly poor,and the voltage is exceedingly high. The last state existed whenattempts were made that failed, although in others that have succeededthe voltage is low, being about 300 volts. The aim has always been toproduce a cheap system, a system which will compete with the is a very desirable aim, but not one that is absolutely necessary,and from the fact that cable traction companies will put in cable sys-tems where the track construction alone costs very nearly $100,000 per 776 THE STREET RAILWAY JOURNAL.
