hands.  A convenient article where a ladle and strainer are needed is to swing a cup-shaped strainer under the bowl of a ladle as shown in the illustration.  The strainer can be held in place with small bands that fit loosely over the handle and a small tip soldered to the ladle.  These will allow the ladle to be turned, leaving the strainer always in position.  A large sized ladle, equipped with a strainer, is just the thing for painters to dip and strain paint, while a small one is of great assistance to the housewife for dipping and straining soups, jellies, etc.  —­Contributed by W.

** Cleaning Gloves [302]

A solution consisting of 1 dr. of sodium carbonate and 1 qt. of milk makes an excellent cleaner for motorists’ gloves.

** Turpentine in Cutting Oil [302]

When cutting steel or wrought iron in a lathe, milling machine, drill press or planer, it is sometimes necessary to leave a smooth surface.  Oil, or various cutting compounds of oil, is used for this purpose and to keep the surface cool.  If a little turpentine is added to the oil, it will greatly assist in leaving a smooth surface.  A proportion of one-quarter turpentine is good.

** Center of Gravity Experiment [302]

This experiment consists of suspending a pail of water from a stick placed upon a table as shown in the accompanying sketch.  In order to accomplish this experiment, which seems impossible, it is necessary to place a stick, A, of sufficient length,

[Illustration:  Experiment]

between the end of the stick on the table and the bottom of the pail.  This makes the center of gravity somewhere near the middle of the stick on the table, thus holding the pail as shown.

** Lathe Accuracy [302]

A heavy lathe cut will not do accurate work.

** An Outdoor Gymnasium part III-The Horse [303]

The German horse is that peculiar piece of apparatus which is partly a horizontal obstruction to leap over, partly a barrier for jumps, partly a smooth surface of long and narrow dimensions over and about which the body may slide and swing, and partly an artificial back for the purpose of a peculiar style of leap frog.

[Illustration:  The German Horse]

To make a horse for the outdoor “gym” requires no difficult work save the preparation of the top or body of the horse.  The making of the regular gymnasium horse requires a very elaborate wood-working and leather upholstering plant, but the one used for outdoor work can be made of a log of wood.  Procure from a saw mill, wood yard or from the woods, one-half of a tree trunk from a tree 9 to 15 in. in diameter—­the larger the better.  The length may be anywhere from 4 to 7 ft., but 5 ft. is a good length.
