The steady growth in popularity of lawn tennis as well as the splendid exercise that results from playing this game has given it a sure place in the field of athletic sports. It is a game that requires a great deal of skill, and as no one realizes this fact more than those who are experts, a beginner should not be deterred from playing tennis simply because he may fear the criticism of the more experienced. The only way to learn the various strokes and to be able to play a good game is to practise at every opportunity. It is better to play against some one who is more skilful than ourselves and who will keep us on our mettle to make a good showing. The eye and the muscles must work automatically and with precision. No amount of written instructions can give us this skill. The personal outfit for playing tennis is of course very simple. Every player should own his racket and become accustomed to it. They cost almost any price up to eight dollars, which will buy the very best rackets made. The weight and size of the racket will depend on our strength. The average weight for a man is about fourteen ounces and for a boy an ounce or two lighter. A skilful player becomes so accustomed to the feeling and weight of his own racket that often he will play an indifferent game if he is forced to use any other. The game of lawn tennis was first played on a lawn or grass court, and many players still prefer this kind of a court, but the difficulty of obtaining a good sod, and after having obtained it the greater difficulty of keeping it in good condition, have increased the popularity of a skinned or clay court, which is always in fair condition except immediately after a heavy rain. The expense of maintaining a tennis court is more than most boys or most families would care to undertake. As a rule, tennis courts fall in the same general class with golf links in that they lend themselves readily to the joint ownership of a club or school, where the expense falls on a number rather than on an individual. In a great many places the boys of a town or village have clubbed together and have obtained permission from some one owning a piece of vacant ground that is not likely to be sold or improved within a few years and have built a tennis court on it. This arrangement helps the appearance of the land, that should be secured at a very low rental, or none at all if the owner is public spirited and prefers to see the boys of his town grow up as healthy, athletic men rather than weaklings who have no place for recreation but in the village streets, where passing trucks and automobiles will endanger their lives, or at least cause them to be a nuisance to the public.
