���Frying Eggs by Means of an Incandescent Bulb
AN ordinary in- candescent bulb, together with some sand and a tin can, can be used for frying eggs to suit the taste of the most critical. Pro- cure a can large enough so that a space of J^ in. will remain between its sides and the bulb at its widest part. Cut a hole in the bottom of the can to fit an electric socket. Screw in the bulb and fill the can with sand as shown. Place the pan on the top of the can and be sure it fits tightly. Turn on the current ; in a very few minutes sufficient heat will be generated to cook the eggs. If left longer, the sand and glass will become almost red-hot. — Wm. Harrier.

���T".
��strument that will be found handy for punching holes in spring-steel, such as a clock-spring. It con- sists of a link from an automobile chain, one pin of which A is filed flat like the end of a punch. By placing the steel spring over the hole D and entering the pin B in hole C, a sharp blow with a hammer over A will cut a clean hole through the spring. Being of steel, the pins A and B may easily be hardened. — M. F. Vandersdale.
An Improvised Pipe-Wrench
APIPE-wrench can be im- provised from a solid wrench A and a coarse, sharp file. The file B is placed in the lower jaw and raised with slugs of metal, if necessary, until the desired grip is obtained on the pipe between the upper jaw and the file surface. This expedient will prove of value in an emergency.

� � � �^/.
��card, similar to the regular double card used for a return mes- sage, may be used for making a car- bon copy. The carbon is slipped between the two folds of the card in writing; then the copy is torn off along the central perforated line.
For this purpose a comparatively thin card is required.
This scheme is especially valuable to clubs and business houses who have to send out hundreds of short communica- tions. — F. P. Mann.
Improving a Drawing-Ink Bottle
THE quill, usu- ally attached to the stopper of a drawing-ink bottle, necessitates several dips into the ink before a sufficient quantity is obtain- ed for transferring to an instrument. By slitting the quill on both sides of the point and standing it on the point, with a heavy object bearing down on the stopper, the tip becomes horizontal, forming a small cup, which will retain a large quantity of ink. — C. Nielsen.
Hints to the Mortor- Cyclist
THE appearance of old and rusted cylinder heads can be great- ly improved by ap- plying ordinary stove small brush.
Bent crank-hangers can be straight- ened by putting a piece of one-inch pipe over the end of the hanger and exerting a little pressure.
A wrench for the bolts in the crank case can be made by grinding or filing a screwdriver bit into the desired shape, as shown in the diagram. The bit is then placed in the brace and used like a socket-wrench. — E. H. Dodge.
