illustrations accompanying this article. Along the rear end of
the garden he has built a railroad from wall to wall, in that distance
overcoming the inconveniences of the ground which usually require the
mechanical ability of railroad builders. The road runs from a little
station called Chicago at one end to a small station at the other end
known as Jericho. It is complete in every detail, and as thoroughly so
as if it were one of the great lines that run across England. The two
stations even have advertisements pasted over them, as any ordinary
station does; and the terminal facilities, though they are small and
rather simple, are in their way as complete as in any full-size
railroad.

The track is over 80 feet in length, with a gauge of 2-5/8 inches; and
in order that he might get in in these 80 feet all the different forms
of railway construction Dr. Warneford has made the track so that it runs
over some of the uneven spots in his yard, and in this way, in the
places where bridges are required, he has constructed that form of
bridge which would naturally be best suited to the particular form of
ravine or cavity over which the road is to run. One of the prettiest of
these bridges is a thoroughly constructed cantalever bridge, on the form
of the great Forth Bridge between Scotland and England, which passes
over a little excavation immediately after the train has come out of a
long, thoroughly constructed tunnel, the entrance to which appears in
two of the illustrations. Another bridge is a perfectly constructed skew
arch, which the train crosses a few feet after leaving Chicago. Then
comes the model of an American trestle, and after passing over this the
road runs through the tunnel, over the cantalever bridge, through a
cutting, and finally over a steel tubular bridge into Jericho.

Besides all these constructions, the proportions of which can be easily
seen by comparing them with the ordinary size bricks of the stone wall,
the road is fully equipped with complete sets of signals, which can be
and are worked with telegraph wires and posts. There are not only
signals for connections and ordinary use, but Dr. Warneford has even
constructed a fog-signal apparatus, which is worked by a spring when the
engine passes over it, causing a hammer to fall on a small blank
cartridge; and this, exploding, is the signal f
