THE SIGNAL SYSTEMS EXPONENT.

1t is said that the above mentioned company does
two and a half times much business as any

In England. practically every mile of passenger
track Is covered with block signals; in the United
States and for the set forth earlier, only
about 20 per is thus protected. Had 1t been
possible TO have equipped all of our railroad mile
age with such elaborate and approved system
that just described. it is probable that every
comparison OF English and American accident sta
tstics would not result, at least not TO such an
extent as at present in our discontinue Not only
that but the vastly increased security and ais
patch such efficient and comprehensive equipment
would impart TO the operation OF our roads would
eppreciably reduce the estimates as to the added
trackage required to do the countrys business, for
the ample protection IL affords would enable each
road not only many more trains but TO run
them more quickly, such is the certainty and ex-
actitude OF its workings-as the reader must have
gathered If he has carefully studied the foregoing
outline OF the system. An opinion expressed by
