��Carrying the Cook- Stove on the Automobile Trip

��The tiny gasoline stove folds up into a box after the meal is cooked

��vent of the summer season the automobile assumes a still greater im- portance in the life of the possessor, and its equipment re- quires expansion. Nature fairly shouts imperative calls to far-away places. Unfortunately, when the calls are obeyed the obedient ones often find their hunger for the vast

out-of-doors appeased at the expense of their more material appetites. Sandwiches, however attractively made up, are not continually satisfying. The truly wise will provide a small stove, on the order of the one illustrated, on which really appetizing little meals may be prepared.

The one shown is nine by nine by four inches and weighs only eight pounds. ^ It has one burner and a tiny oven. Gasoline is used for fuel. The tank is protected from the flame by means of a jacket, double air chamber and a partition. It holds enough gasoline for one and one-half hour's con- tinuous use, and may be replenished from the tank of the car.

���without being over-strained and nourished without being overfed, in order that they may be able to resist the attacks of micro- scopic enemies which cause disease and decay. Under favorable conditions these cells will live indefinitely without showing signs of age or loss of vitality. Therefore the con-, elusion is reached that the "three score years and ten" are not fixed by any natural law but rather by the con- ditions under which men live and by their personal habits. The athletic champion, then, who lives under the best hygienic conditions and observes the law of temperance in all things and at all times, should be able to "sit tight" on his pedestal so long as he desires.

���At What Age Does the Athlete Begin to Lose Form?

" 'T^HREE score years and ten," X tradition says, is the span of a human life. This must be divided into three periods to include prepara- tion, efificiency and decay, each period lasting nearly twenty-five years. With the athlete, it is still more severe. Few men at thirty-five, it is said, have the reserve vitality and endurance that they had at twenty-five. Therefore the edict has gone forth that at thirty-five the athlete must let up in violent competitive work and gradually back out of the front ranks.

But there is no scientific evidence to show that this is necessary. The human body is simply an assemblage of cells, which must be kept active

��A Novel Bicycle Exerciser for the Wounded Soldiers

THE accompanying photograph shows two soldiers sufficiently convalescent from leg wounds to be in need of exercise. On this novel bicycle they are afforded companionship as well as exercise.

���Two bicycles minus their front wheels and supported by iron braces enable two men to exercise at the same time
