There are two kinds of balancing to which we shall allude; namely, the balancing of other bodies, and the balancing of our own. All feats of balancing depend upon the centre of gravity being uniformly preserved in one position. The centre of gravity is that point, about which all the other parts exactly balance each other. If a body be freely suspended upon this point, it will rest with security, and as long as this point is supported, it will never fall, while in every other position it will endeavour to descend to the lowest place at which it can arrive. If a perpendicular line were drawn from the centre of gravity of a body to the centre of the earth, such a line would be termed the line of direction, along which every body supported endeavours to fall. If this line fall within the base of a body, such a body will be sure to stand. When the line of direction is thrown beyond its centre, unless the base be enlarged to counterbalance it, the person or body will fall. A person in stooping to look over a deep hole, will bend his trunk forward; the line of direction being altered, he must extend his base to compensate for it, which he does by putting his foot a step forward. A porter stoops forward to prevent his burthen from throwing the line of direction out of the base behind, and a girl does the same thing in carrying a pail of water, by stretching out her opposite arm, for the weight of the pail throws the centre of gravity on one side, and the stretching out of the opposite arm brings it back again, and thus the two are balanced. The art of balancing, therefore, simply consists in dexterously altering the centre of gravity upon every new position of the body, so as constantly to preserve the line of direction within the base. Rope-dancers effect this by means of a long pole, held across the rope; and when the balancing-rail is mounted, it will be found necessary to hold out both the arms for the same purpose; nay, even when we slip or stumble with one foot, we in a moment extend the opposite arm, making the same use of it as the dancer does of his pole. A balancer finds that a body to be balanced, is the best for his purpose if it have a loaded head, and a slender or pointed base, for although the higher the weight is placed above the point of support, the more readily will the line of direction be thrown beyond the base, yet he can more easily restore it by the motion of his hand,--narrowly watching with his eyes its deviations. Now the same watchfulness must be displayed by the gymnastic balancer: he first uses the balancing pole,--he then mounts the balancing bar without it. On mounting the bar, the body should be held erect, and the hands must be extended. He must then learn to walk firmly and steadily along the bar, so as to be able to turn round, and then he should practise going backwards. Two balancers should then endeavour to pass each other on the bar; afterwards, to carry each other, and bodies of various weights, in various positions. Walking on stilts is connected with balancing. A person can walk with greater security upon high than on low stilts. In some parts of France, the peasantry, in looking after their sheep, walk generally on stilts, and it only requires practise to make this as easy as common walking. Some few years ago, several of these stilt-walkers were to be seen in London, and they could run, jump, stoop, and walk with ease and security, their legs seeming quite as natural to them as those of the Stork.
