[Illustration: FIG. 4.]
Take pieces of stiff copper wire three inches long, and with pliers
bend over one end of each to form a hook, and the other ends into a
small ring. Turning your car upside down, lay one of these wires in
the middle of the end, with only the hook sticking out, and fasten it
by a small screw through the ring (_fig. 6_); do the same at the other
end, and then with some small brass curtain rings, which cost two or
three cents a dozen, you can couple your cars nicely.
Baggage and freight cars you can make in the same way, only cutting one
large door in the side. You can make the cars as showy as you please,
with paint of different colors, and finish them with a piece of muslin
glued part way over the windows inside for shades. And now last comes
the engine.
