ting the ominous warning of 40 shillings fine if he does so, and
the liability of having his sweet dreams interrupted by an occasional
inspector who asks to see the denomination of his ticket. All
compartments intended for the use of smokers are plainly marked and
are to be found in each class. Almost the entire part of the railroads
within the thickly settled portions of the city run in closed tunnels.
Outside of this they frequently run in open cuttings, and still
further out they run on to elevated tracks.

With regard to the equipment of the suburban or surface lines not
belonging to the underground system the description is about the same.
The cars are generally four compartments long and sometimes not
exceeding three. They are coupled together with a pair of links and
fastened to the draw bar on one car and the other thrown over a hook
opposite and brought into tension by a right and left hand screw
between the links. This is obviously very inconvenient for shunting
purposes, especially as the cars are not provided with hand brakes and
no chance to get at them if there were any. Consequently it appears
that when a train is made up it stays so for an indefinite period. A
load of passengers is brought into the station and the train remains
in position until it is ready to go out. As the trains run very
frequently this appears to be a very economical arrangement, as no
shunting tracks are needed for storage. The engine which brings the
train in of course cannot get out until the train goes out with the
next load. Turn tables for the locomotives are but very little used,
as they run as double enders for suburban purposes.

In conclusion it will be safe to say that the problem of rapid transit
for a city as large as London is far from solved by the methods
described. Although there are a great many miles of underground lines
and main lines, as they have been called throughout the paper, and
although grade crossings have been entirely abolished, allowing the
trains to run at the greatest speed suitable to their frequency, still
there are a great many sections which have to depend entirely upon the
omnibus or tram car. The enormous expense entailed by the construction
of the elevated structures can hardly be imagined. We have but one
similar structure in this country, which is that running from the
Schuylkill River to Broad Street station, in Philadelphia. The
underground system is even more expensive, especially in vie
