Shooting Animals by electricity is certainly a most original game, and it will furnish a vast amount of amusement to all. The game is patented and copyrighted--because it is really a brand-new idea in games--and it brings into use that most mysterious something called electricity. While the electricity is perfectly harmless, there being no batteries, acids or liquids, it is very active and you will have plenty to laugh at. It is so simple that the smallest child can play it and so fascinating that grandpa will want to try it.
The "game-preserve" is neatly printed in colors, and the birds and wild animals are well worth hunting. Each has a fixed value--and some of them must not be shot at all--so there is ample chance for skill. Tissue-paper bullets are actually shot from the "electric gun" by electricity, and it is truly a weird sight to see them shoot through the air impelled by this unseen force.
The Outfit contains the "Game-Preserve," the "Electric Gun," the "Shooting-Box," and the "Electric Bullets," together with complete illustrated directions, all placed in a neat box.

Electric Air-Ships and Other Games
This is the age of air-ships and electricity, so what could be more up-to-date than electric "air-ships" that will float and dive and race around at the will of the operator? In this game Mr. St. John has again made use of a scientific principle, the "air-ships" being actually controlled by electricity. They are made to act in a most peculiar manner, with no wires, no fuss, no danger. They are under perfect control and can be made to ascend to the ceiling, drop to the floor or race across the room, as desired. You simply can't imagine how entertaining it is to see a lot of excited people managing these aerial racers, each eager to win.
The outfit contains illustrated directions and materials for two players, including the apparatus for producing the electricity and the "repeller" for managing the "air-ships" in mid-air. The little "air-ships" are actually made of metal and they can be instantly formed. Here's the latest sport for all ages, because the little ones can play too. Get into the game and be an aviator.

REAL ELECTRIC TOY-MAKING FOR BOYS
This book contains 140 pages and over one hundred original drawings, diagrams, and full-page plates.
It measures 5x7-1/2 in., and is bound in cloth.
SECOND EDITION Price, postpaid, .00
While planning this book, Mr. St. John definitely decided that he would not fill it with descriptions of complicated, machine-made instruments and apparatus, under the name of "Toy-Making," for it is just as impossible for most boys to get the parts for such things as it is for them to do the required machine work even after they have the raw materials.
Great care has been taken in designing the toys which are described in this book, in order to make them so simple that any boy of average ability can construct them out of ordinary materials. The author can personally guarantee the designs, for there is no guesswork about them. Every toy was made, changed, and experimented with until it was as simple as possible; the drawings were then made from the perfected models.
As the result of the enormous amount of work and experimenting which were required to originate and perfect so many new models, the author feels that this book may be truly called "Real Electric Toy-Making for Boys."
Every Boy Should Make Electrical Toys.
A MOTOR THAT CAN DO THINGS
The "St J. Motor No. 1" is designed for students and others who want a small motor for experimental purposes as well as for all of the work that any small motor can do. We believe this to be the best small motor made, and we know that it can be used in more ways than any other motor of equal cost ever built. It has four binding-posts,--making it possible to energize the field or armature separately,--and so it can be used in circuits with reversers and rheostats for experiments. The speed and direction of rotation can be changed at will, thus adapting it for running toys, etc. As the binding-posts are mounted upon the frame, this motor can be taken from the base for remounting and using in many ways, and as it has a three-pole armature it will start promptly in any position. The shaft carries a pulley, and a fan can be added at any time. One cell will give a high speed, and more cells may be added, according to the work it has to do.
Motor No. 1 stands 3-1/2 inches high. It is finished in black enamel with nickel-plated trimmings,--strong and well made. With it are furnished three nickel-plated connecting-straps, which are to be used for connecting the field and armature in "series" or "shunt." So much can be done with this motor that it is simply impossible to tell it here; in fact, it is used as the basis for a whole book of 60 experiments called "The Study of Electric Motors by Experiment," and, when used in connection with the other parts of the Motor Outfits, it will give a practical knowledge of motors that no other plan can give.
These motors and motor outfits have been highly praised by electrical experts and educators as being invaluable to students. They can do everything the big motors can do, and if used with the rheostats, reversers and other apparatus in the outfits, the student will have a whole motor laboratory.
Why not get a motor that has brains and that can do tricks and experiments? Any good motor will go when you turn on the power; but that doesn't mean much when it comes to understanding things.

"ST. J." ELECTRIC MOTOR OUTFIT
These outfits have been designed for students and others who want to do real experimental work with motors, so as to get right down to the bottom of the matter and thoroughly master the foundation principles of the subject. It is simply astonishing to see how much can be learned with one of these outfits, especially if the work be done as fully detailed in "The Study of Electric Motors by Experiment." Every electrical laboratory should have one of these sets, and the more you know about motors the more you will appreciate an outfit of this kind.
Don't simply read about motors--get right down to the practical part of it and experiment for yourself. Every experiment will settle an important point in your mind.
ELECTRIC MOTOR OUTFIT No. 2226X contains everything needed for sixty interesting and profitable experiments. With the improved apparatus that we now give we feel that this is the most complete set ever sold for the money. The following articles are included, packed in a wooden box:
THE "ST. J." MOTOR, fully described on another page, is well called "A motor that can do things."
THE FIVE-POINT RHEOSTAT is used as a "starting-box" in the armature-circuit and in various other ways to regulate speed.
THE ELEVEN-POINT RHEOSTAT is used to regulate the "field-magnetism," as one method of speed-regulation, and for other purposes.
THE DOUBLE-KEY CURRENT REVERSER is, really, a key, a two-point switch, and a current-reverser combined. On this account it can be used in many ways, shown in numerous wiring-diagrams.
THE HANDY CURRENT-DETECTOR is used as a current-detector and as a device for studying the counter-electromotive force of motor while running.
THE TWO-POINT SWITCH is useful in quickly switching the current wherever it is needed, and for many other experiments.
THE STRAP KEY protects the batteries and closes the circuit.
THE MINIATURE ELECTRIC LAMP AND SOCKET are used in the motor-circuit to prove certain things and form an attractive addition to the outfit.
THE MAGNETIC NEEDLE in the new outfits is nickel-plated and serves as a compass for studying the magnetism of the poles, etc.
IN ADDITION to the articles mentioned above, the outfit contains a Set of Wires for Connections, a Box of Iron-Filings for studying lines of force, an Experimental Package containing Iron, Steel, etc., three Connecting-Wires, and
BATTERIES are not included, unless ordered extra. Three of our No. 1101 batteries cost 36c., and extra postage for 2 lbs.

Fun With Telegraphy
TWO GREAT OUTFITS FOR STUDENTS
These two outfits are similar in construction, although they differ in details, each being designed for its special work. The "keys," "sounders" and "binding-posts" are neatly mounted upon ebonized bases measuring 6-1/2x3-3/4 in., these also serving as sounding-boards.
"Fun with Telegraphy" is the original low-price telegraph outfit for students that has sold by the thousands and given universal satisfaction. It is considered the best 50-cent outfit ever produced, and, although we have made several improvements lately, the price is the same as before. In connection with a peculiar oscillating electro-magnet and a queer anvil, the sounding-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.
Outfit: Illustrated Book of Instructions, called "Fun with Telegraphy"; Telegraph "Key"; Telegraph "Sounder"; Nickel-Plated "Binding-Posts"; Insulated Wires for Connections.
