��The turbine consists of but two mov- ing parts, a driving member attached to the engine-shaft and a driven member, fastened to the front end of the propeller- shaft of the car. Both members are con- structed exactly alike and are made up of two circular housings with blades or fins radiating from a central rectangular cham- ber. The two members stand apart and touch only at the bearings on the shafts. The space inside the housing is par- tially filled with oil. When the engine of the car is started, the blades of the member attached to the engine force the oil up against the blades of the housing mounted on the propeller shaft so that it, and finally the rear wheels are turned to make the car go. The speed of the car is controlled by the throttle, although the device may be thrown out of contact with the flywheel if it is necessary to shift the gears in the usual manner.

As long as motor-driven vehicles are used, the quest for im- provements and labor- saving devices will go on, stimulated partly by economic dictates and partly by the inherent inclination in the human race to simplify me- chanical contrivances.

��Making It Easy for Old Dobbin to Eat Out of the Feed Bag

���The spring keeps the feed bag adjusted so that the horse can get at the oats

��HE feed-bag support invented by William Meier of Jersey City, N. J., is designed to overcome the difficulties invariably connected with the use of the feed bag. This bag is provided with a spring so that it will adjust itself when the food gets out of reach of the horse as it diminishes in quantity. Even under the most favorable conditions part of the oats will be spilled in the horse's attempts to get at it. Mr, Meier's invention consists of a yoke-shaped frame of heavy spring wire, which is suspended from the head and neck of the animal in the manner shown in the il- lustration. The bag is suspended by a cord running through a loop of the spring.

��Practicing the Head-Hold with a Wooden-Headed Adversary

BOXING with a dum- my which can't be knocked down is a well- known and recognized form of training for pugilists, but hitherto wrestlers have been rather unprovided for in this respect. Now, how- ever, Mr. B. C. Sandow, of Rochester, New York, has brought out a dum- my head to train a man to give enormous pres- sure in the head-lock.

This apparatus is a wooden, life-sized head, made in two equal pieces divided down the center of the face. The halves are kept apart by three coil springs. The wrestler practices squeezing the halves together, as he would in the head-lock, until he can conquer the tension of the springs.
