Fun With Telegraphy
BOOK AND COMPLETE OUTFIT.
TELEGRAPHY is of the greatest importance to all civilized nations, and upon it depend some of the world's most important enterprises. Every boy and girl can make practical use of telegraphy in one way or another, and the time it takes to learn it will be well spent.
THE OUTFIT.—Mr. St. John has worked for a number of years to produce a telegraph outfit that would be simple, cheap, and practical for those who wish to make a study of telegraphy. After making and experimenting with nearly one hundred models, many of which were good, he has at last perfected an instrument so simple, original, and effective that it is now being made in large quantities.
The sounders are so designed that they will work properly with any dry cell of ordinary strength, and this is a great advantage for practice lines. Dry batteries are cheap and clean, and there are no dangers from acids.
The outfit consists of the following articles, placed in a neat box: One Book of Instruction, called "Fun With Telegraphy"; one Telegraph "Key"; one Telegraph "Sounder"; Insulated Copper Wires for connections. The "key" and "sounder" are mounted, with proper "binding-posts," upon a base of peculiar construction, which aids in giving a large volume of sound.
CONTENTS OF BOOK.—Telegraphy.—The Outfit.—A Complete Telegraph Line.—Connections.—The Telegraph Key.—The Sounder.—The Battery.—A Practice Line.—A Two-instrument Line.—Operation of Line.—The Morse Telegraph Alphabet.—Aids to Learning Alphabet.—Cautions.—Office Calls.—Receiving Messages.—Remember.—Extra Parts.
ABOUT BATTERIES.—For those who cannot easily secure batteries, we will furnish small dry cells, post-paid, at 15 cents each, in order to deliver the outfits complete to our customers. This price barely covers the total cost to us, postage alone being 6 cents.
