board aids in giving out a loud, clear
click that is found elsewhere only in noisy railroad sounders. This
outfit is best adapted for a learner's set of one instrument and a
battery to be used on the table for practising, either with or without
the "codegraph," and not for telegraphing over wires to other stations.

"Improved Telegraphy No. 2."--In answer to a number of requests for an
improved outfit for regular line work between two stations a few hundred
feet apart, we now offer this set, which is, in general, similar in plan
to our first "Telegraphy No. 2." We have replaced the single
electro-magnet of the old set, as shown in the cut, with two larger ones
of superior construction, thus making the instrument much more
sensitive. The key has also been greatly improved, and we now have a
fine set at low cost.

No expensive gravity batteries are needed with this ingenious
arrangement, as it is designed to work with dry batteries which are
clean and cheap. By means of a peculiar switch, either station may
"call" the other at any time, even though the line is kept on "open
circuit." There is absolutely no waste of current when the line is not
in use--and, even then, only at the instant the dots and dashes are
made. This is certainly a great advantage over the old-fashioned methods
with gravity batteries which amateurs have heretofore been obliged to
use. With this instrument you have a learner's set as well as one that
can be used to send messages to another station. If you do not care for
the superior advantages of "Semi-Wireless," this outfit will give entire
satisfaction for ordinary work.

Outfit: Illustrated Book of Instructions called "Telegraphy Number Two";
Improved Telegraph "Key"; Telegraph "Sounder" with Double
Electromagnets: Special "Switch" for controlling the batteries;
Nickel-plated Screw "Binding-posts"; Insulated Wires for connections.
