rod from coming out of its bearings. To prevent the oil gushing out through the slot cut in the brass tube a glass tube was inserted within, its diameter permitting a close fit in the hole of the brass tube. The length of the glass tube brought it into position so that the cap B clamped it in place.

��A float gage made of odds and ends for finding the oil level in a large storage tank
The markings on the outside of the tube A for indicating the quantity of oil in the tank were determined by turning a }/£ gallon of oil in at a time and making a mark. The marks were cut in with a machinist's scriber. — Adolph Klein.
��An Emergency Repair on a Leaking Water Pipe
THINGS often break down at the most inopportune times. A num- ber of years ago, the writer was called upon one Sunday morning to stop a leak in a cold water pipe which threatened to ruin the ceiling below. No plumber was to be had. The leak could have been stopped by shutting off the water altogether ; but for several reasons this was impracticable for any length of time. I had a supply of friction tape such as is used by electricians for wrapping spliced wire joints. Shutting the water off in the cellar for a few minutes, I wrapped the tape closely over the hole, putting on several layers. Over this tape I wrapped sev- eral thicknesses of twine of which a plentiful supply was on hand. When the water was turned on, the leak was found to be com- pletely stopped . The tape was left on the pi pe seven days and answered well until a perma- nent repair was made. — W. S. Standiford.
��THE tired shop-girl who is compelled to board a crowded car every day will appreciate this little hanger which she can carry in her pocket or bag. It consists of two large bone rings, such as are used by harness-makers, connected by a half-yard strip of strong webbing or tape, which can be quickly slipped through the usual hanger without inconveniencing another passenger who may be using it. Both rings are to be held together in the hand. The short woman who has difficulty in reaching the usual hangers will also find this convenient. — J. E. McCoy.
��A Garage Air-Compressor Made from an Old Automobile Engine
AS an air-compressor was badly needed in our garage, in spite of the fact that the quantity of business did not warrant the purchase of a high-priced machine, we built one from an old discarded engine from a small car. The engine had its water-jacketed head broken in half. On account of this only two cylinders were used for the compressor. The old counter- shaft and two pistons were assembled and bolted down to timbers. A heavy flywheel was keyed to the end of the shaft and this was belted to the line shaft of the garage. This outfit easily kept up from ioo lb. to 135 lb. pressure. To hold this pressure

��An old engine mounted on a wood base and driven by another engine for use as an air-compressor
a tank was constructed from a 10-ft. length of 8-in. gas main, which, being capped at each end, had an inlet and an outlet hole drilled in the caps. With this equip- ment the garage has ample air pressure for all purposes in the shop besides free air outside for tire pumping. — L. A. Bennett.
