** New Method of Lifting a Table [99]

To perform this feat effectively the little device illustrated
will be required. To make it take a sheet-iron band, A, 3/4 in.
wide and attach a strap to fasten on the forearm between the wrist
and elbow. Put a sharp needle point, B, through the sheet-iron so
that it extends 3/4 in. outward. Make one of these pieces for each
arm. In lifting the table first show the hands unprepared to the
audience and also a tight table, removing the cover to show that
the surface of the table is not prepared in any way. Then replace
the table,

rest the hands upon it and at the same time press the needle
points in the arm pieces into the wood of the table, which will be
sufficient to hold it, says a correspondent of the Sphinx. Then
walk down among the audience.

** How to Make a Paddle Boat [100]

A rowboat has several disadvantages. The operation of the oars is
both tiresome and uninteresting, and the oarsman is obliged to
travel, backward.

[Illustration: Paddle Boat]

By replacing the oars with paddles, as shown in the illustration,
the operator can see where he is going and enjoy the exercise much
better than with oars. He can easily steer the boat with his feet,
by means of a pivoted stick in the bottom of the boat, connected
by cords to the rudder.

At the blacksmith shop have a 5/8-in. shaft made, as shown at A,
Fig. 2. It will be necessary to furnish a sketch giving all the
dimensions of the shaft, which should be designed to suit the
dimensions of the boat, taking care that sufficient clearance is
allowed, so that the cranks in revolving will not strike the
operator's knees. If desired, split-wood handles may be placed on
the cranks, to prevent them from rubbing the hands.

The bearings, B, may be made of hardwood, but preferably of iron
pipe filled with melted babbitt. If babbitt is used, either
thoroughly smoke or chalk the shaft or wrap paper around it to
prevent the babbitt sticking. The pieces of pipe may be then
fastened to the boat by means of small pipe straps, such as may be
obtained at any plumber's at a very small cost.

The hubs, C, should be made of wood, drilled to fit the shaft and
mortised out to hold the paddles, D. The covers, E, may be
constructed of thin wood or galvanized iron and should be braced
by triangular boards, as shown in Fig. 1. If
