peller is soldered to the propeller-shaft.

The only part of the job that remains is to screw the boiler in place
under the fore-deck of the boat. This done, the _Nancy Lee_ is ready for
her trial. The fore-deck should be made removable by fitting it with
pins or screws with the heads cut off, so that the deck only needs
pushing into place. This little boat should be capable of attaining a
speed of from four to five miles an hour if it is made carefully and
according to the directions outlined in this Chapter.

CHAPTER VII

AN ELECTRICALLY DRIVEN LAKE FREIGHTER

A PROTOTYPE of the model lake freighter described in this Chapter will
probably be familiar to many readers. It is a type of boat used on the
Great Lakes, and, owing to its peculiarity of design, it lends itself
very well to construction in model form.

The lines of the boat may be seen very clearly in Fig. 84.

The hull of the model freighter measures four feet over all, and the
beam at the water-line is 8 inches. The extreme draft will be in the
neighborhood of 5 inches. This model, when completed, will be capable of
carrying considerable weight; in fact, it is able to accommodate
thirty-five pounds in weight when used in fresh water. This will give
the builder an opportunity to install a very substantial power
equipment with little regard for weight.

The hull is made according to the built-up principle, and the
constructor will have to cut his templates before attempting the shaping
of the hull. Owing to the depth of the model, it will be necessary to
use about ten planks. The plank that is used to form the bottom of the
boat is not gouged out. Every other plank is gouged out with a saw and
chisel.

The bottom plank is shaped with a knife to conform to the lines of the
boat. In building up the hull with the planks, they should first be
smeared with glue, and when put in place a few brass brads should be
driven in. As mentioned in an earlier part of this book, iron nails
should not be used in work of this nature, owing to the fact that they
will rust and cause trouble. The brass brads are placed about one inch
apart the entire length of the boards. The hull is finished with a plane
and sandpaper, and after it has been brought to shape in this way and
finished, a coat of paint is applied. Black with dark red trimmings
makes a very good combination for a boat of this type.

The deck is made
