The first exercise that young boys learn is "shoulder and legs," which is practised assiduously till performed with ease and rapidity. After this comes "splits." This exercise looks as if it ought to be not only uncomfortable but painful; but a strong proof that it is neither was afforded me involuntarily by one of the little boys. He did it repeatedly for his own benefit when off duty! After this the boy learns "flip-flap," "full-spread," and a number of intricate gymnastics with which the public is familiar. In all these performances boys are very much in request, partly because they are more popular with the public, and partly because in a variety of these gymnastic exhibitions men are disqualified from taking any part in them owing to their weight. In the figure technically known as "full spread" (shown in illustration), it is essential that the topmost boy shall be slightly made and light in weight; but even under these conditions the strain on the principal "supporter" is enormous. As regards danger, so far as I have been able to learn from a good deal of testimony on the point, there is very little of any kind. The only really dangerous gymnastic turn is the "somersault," which may have serious results, unless done with dexterity and delicacy. There is no doubt that exercise of this kind is beneficial to the boys' health. Several boys in excellent condition, with well-developed muscles and chests, assured me they were often in the "'orspital" before they became acrobats. [Illustration: THROWING KNIVES.] Their improved physique is possibly in a great measure due to the capital feeding they get, it being obviously to the advantage of the "father" to have a robust, rosy-faced company. Master Harris, of the "Yokohama Troupe," informed me that he generally has meat twice a day, a bath every evening (gymnasts are compelled by the nature of their work to keep their skins in good condition by frequent bathing), that Mrs. Bale was as kind to him as his own mother, and that he thought performing "jolly." He further informed me that he got three shillings a week for pocket-money, which was put into the bank for him. [Illustration: BALL EXERCISE.]
