ely defy detection and do much toward bettering the
general appearance of the craft upon which they are used.

A simple searchlight, easily made by the model boat builder, is shown
in Fig. 97. This is an electric light, and the batteries used to propel
the boat can be used for the light. First a small circular piece of wood
is cut out, as shown at _A_, Fig. 97. The center of this is drilled out
to accommodate a small flashlight bulb. A tiny brass screw is then
driven into the piece of wood, so that it will come in contact with the
center of the base of the flashlight bulb. This little screw forms one
of the electrical contacts, and one of the wires from the battery is
attached to it.

A little strip of brass is then cut as shown in _B_, Fig. 97, and
provided with three holes, one hole at each end and one in the middle.
The brass is bent into a semicircular shape, so that it will be just a
little larger in diameter than the outside of the wooden piece in which
the flashlight bulb is mounted. This little piece is then fastened to a
wooden post with a small brass pin, as shown in Fig. 97. Two more pins
are used to hold the wooden piece to the searchlight proper. One of
these pins is driven through the wooden piece until it comes in contact
with the base of the flashlight bulb. This forms the other electrical
connection, and the second feed wire from the battery can be attached to
the little brass piece that holds the searchlight. Both the feed wires
from the battery can come up through a hole in the deck close to the
wooden post upon which the searchlight is mounted.

Bollards are very easily made. Reference to Fig. 98 will make this
clear. First a little strip of brass is cut, and this is drilled as
shown with two holes, one at each end and two smaller holes in the
center. Two little circular pieces of wood are then cut, with a hole
through the center. A brass screw passes through these and into the deck
of the boat. The brass screw should not be driven in too far, since the
bollards should be free to revolve. It is also possible to use brass
tubing instead of wood if the proper size is in the model-builder's
shop.

A word will be said here about finishing the deck of a model boat. It is
a very tedious job to cut separate pla
