wood frame, constructed of 3/4-in. square material in any size,
but 12 by 24 in. is large enough. The end pieces B are fastened on
top of the long side pieces A, and the cheesecloth C stretched and
tacked over them, as shown.

The prints should be placed face up on the cloth, and the frame
set near a window. If the stretcher is made in

this way, the air can enter from both top and bottom, and the
prints will dry rapidly. Several of these frames can be stacked
and a large number of prints thus dried at the same time.

** A Temporary Funnel [275]

The amateur photographer often has some solution which he desires
to put into a bottle which his glass funnel will not fit, says the
Photographic Times. The funnel made by rolling up a piece of paper
usually allows half of the solution to run down the outside of the
bottle, thereby causing the amateur to be dubbed a "musser," A
better way is to take an ordinary envelope and cut it off as shown
by the dotted lines. Then clip a little off the

point, open out, and you have a funnel that will not give any
trouble. It is cheap and you can afford to throw it away when
dirty, thereby saving time and washing.

** An Electric Engine [276]

The parts of this engine are supported on a base 3/4 in. thick, 4
in. wide and 7 in. long. The upright B, Fig. 1,

[Illustration: Shaft Turned by Magnetism]

which is 1/2 in. thick and 3 in. high, is secured across the base
about one-third of the distance from one end and fastened with a
wood screw put through from the under side. The magnet core C is
made of a carriage bolt, 2-1/2 in. long, which is fastened in a
hole in the top part of the upright B so that the end C will
protrude slightly. Before placing the bolt in the hole of the
upright, slip on two cardboard washers, each 1 in. in diameter,
one at the head end and the other against the upright B. Wrap a
thin piece of paper around the bolt between the washers and wind
the space full of No. 22 gauge magnet wire, allowing each end to
project for connections.

The driving arm D, Figs. 1 and 3, is made of a piece of soft sheet
iron, 1/2 in. wide and 3 in. long. A small block is fastened to
the lower end of the metal and pivoted between two uprights, 1/2
in. high, which are fastened to the base. The uprights on each
side of the block are better shown in Fig.
