distance apart and throw the ball vigorously, without using the legs hardly at all, rests the lower limbs and gives a somewhat violent exercise to the upper parts of the body. On the other hand, if you run most of the way at a good speed keeping a wide distance and seldom throw the ball, the lower limbs have more work to do. The quickness of action and the speed required, involve no great muscular strain but they exercise the lungs, while the vigorous effort, as you grasp the ball and catch and throw it, although it needs no speed of foot, yet braces and strengthens the body. If the ball is thrown both vigorously and at full speed there will be a considerable strain on the body and on the lungs: it will be indeed the most violent form of exercise possible. But how far this strain should be relaxed or intensified, as circumstances require, it is impossible to set down in writing--exact quantities should never be stated; in actual practice it is easy enough to discover the proper limit and to instruct others. On actual experience all depends. The quality of a thing is useless if it is spoilt by a wrong quantity, and this will be the business of your trainer, who will act as guide in all matters of exercise. ‘But I must bring my subject to an end. In addition to all the other advantages, which, as I have said, the small ball possesses, there is one more which I should not like to omit. It is free from all the risks to which most other athletic exercises are liable. Before to-day many a man has died of a broken blood-vessel after a violent race: and so also the practice of loud and furious shouting, if pursued without intermission for some time, has often proved the cause of very serious mischief. Continuous horse-riding ruptures the parts about the kidneys and often injures the chest, besides in some cases doing harm to the generative organs. I say nothing of the mistakes that horses make, whereby frequently their riders have been unseated and killed on the spot. Many men have also been hurt while jumping, or throwing the discus, or turning somersaults. As for the frequenters of the wrestling school, what need I say of them? They are all scarred more shamefully than the Curse-hags of whom Homer tells us. The great poet describes them: “Lame and wrinkled and with eyes askance.” And so with the wrestling master’s pupils, you will find them lame, distorted, battered, and maimed in some part at least of their body. Since then, in addition to the other advantages, this freedom from danger is the particular attribute of small ball games, they must be regarded as the best of all inventions, so far as actual utility is concerned.’
