Walking or running: provided either of them be not carried to fatigue,--the slightest approach to it should warn a youth to desist from carrying it further. Walking exercise is not sufficiently insisted upon. A boy or a girl, to be in the enjoyment of good health, ought to walk at least ten miles every day. I do not mean ten miles at a stretch, but at different times of the day. Some young ladies think it an awfully long walk if they manage a couple of miles! How can they, with such exercise, expect to be well? How can their muscles be developed? How can their nerves be braced? How can their spines be strengthened and be straight? How can their blood course merrily through their blood-vessels? How can their chests expand and be strong? Why, it is impossible! Ill health must be the penalty of such indolence, for Nature will not be trifled with! Walking exercise, then, is the finest exercise that can be taken, and must be taken, and that without stint, if boys and girls are to be strong and well! The advantage of our climate is, that there is not a day in the whole year that walking exercise cannot be enjoyed. I use the term enjoyed advisedly. The roads may, of course, be dirty; but what of that A good thick pair of boots will be the remedy. Do then, let me entreat you, insist upon your--girls and boys taking plenty of exercise; let them almost live in the open air! Do not coddle them; this is a rough; world of ours, and they must rough it; they must be knocked about a great deal, and the knocks will do them, good. Poor youths who are, as it were, tied to their mother's apron strings, are much to be pitied; they are usually puny and delicate, and effeminate, and utterly deficient of self-reliance. 340. _Do you approve of--horse or pony exercise for boys and girls_? Most certainly I do; but still it ought not to supersede walking. Horse or pony exercise is very beneficial, and cannot be too strongly recommended. One great advantage for those living in towns, which it has over walking, is, that a person may go further into the country, and thus be enabled to breathe a purer and more healthy atmosphere. Again, it is a much more amusing exercise than walking, and this, for the young, is a great consideration indeed. Horse exercise is for both boys and girls a splendid exercise; it improves the figure, it gives grace to the movements, it strengthens the chest, it braces the muscles, and gives to the character energy and courage. Both boys and girls ought to be early taught to ride. There is nothing that gives more pleasure to the young than riding either on a pony or on a horse, and for younger children, even on that despised, although useful animal, a donkey. Exercise, taken with pleasure, is doubly beneficial.
