HELLO! Hello! What is it you say? You can really make a telephone? What fun! How far will it work? You think it can be heard a long distance? Very good. Could we manage to construct such a one? How, pray tell us?
The answer which came back over the line we give in a more concise form, as follows:
The best way to make a simple telephone is to procure two round, medium-sized tin baking-powder boxes, and remove the bottoms with a pair of pinchers; then soak two pieces of Whatman’s drawing-paper, or any other strong paper, in a basin of water for a few moments, and when thoroughly wet take them out and place one smoothly over the end of each box. Fasten these down by winding a waxed cotton twine securely over the paper and box, and tying it tightly (Fig. 137). This done, allow the drums to become wholly dry, when they should be firm, even, and without wrinkles. Next cut away that portion of the paper which stands out, frill-like, beyond the string, and paste a narrow strip of paper around over the twine (Fig. 138). Wax a piece of string of the desired length, and with a large needle or pin carefully punch a hole in the centre of each drum; thread one end of the waxed string through one of the holes and make a large knot in the end, then cautiously pull the string until the knot rests on the inside surface of the paper. Connect the other box to the string in like manner, so that the twine will have a box fastened on each end.
The telephone is now ready for use; and if the distance is short, the line may be stretched taut from point to point. But should the space be great, supports will be needed and loops must be made of the twine and fastened at intervals on trees, corners of the houses, or any available points, with the connecting cord passed through these loops (Fig. 139), which act as supports. Keep the course of the waxed string as straight as possible, and, as far as practicable, avoid sharp angles. This style of telephone we know, from personal experience, works perfectly at the distance of fifty yards, and doubtless it will do as well when the line is stretched much farther. Be particular, in selecting the tin baking-powder boxes, to have them round and even; if they are old and battered the experiment may not prove satisfactory. We find the telephone very useful and convenient, besides affording any amount of amusement and fun; with its aid we converse with acquaintances, even though they be at a distance. The friendly little instrument carries the voice all along the slender line to the very ears of our best friend, and we can chat away as freely and almost as easily as if side by side. What a comfort to be able, when seated in your own room, to listen to the voice of some companion, living perhaps blocks away, and it is such a pleasure, too, to have questions answered immediately, which is impossible in communications made by letter. Nor is this a pleasure to be enjoyed at rare intervals, for as long as the telephone lasts it can be used at any time for a short or long talk, as one may feel inclined. The consultations, the plans, the sport, and merriment to be had with the telephone can scarcely be appreciated by one who is not the happy possessor of such an instrument.
Listening.
When the weather will not permit of a walk or a visit, the telephone brings us, if not face to face, at least within speaking distance of those to whom we desire to talk.
