William T. Tilden,
The Art of Lawn Tennis
“ Do not start children playing tennis with an under-sized racquet. It weakens the wrist and does not aid the child in learning strokes. Start a child, boy or girl, with a full-sized racquet of at least 13 ounces.After you have acquired your racquet, make a firm resolve to use good tennis balls, as a regular bounce is a great aid to advancement, while a "dead" ball is no practice at all.If you really desire to succeed at the game and advance rapidly, I strongly urge you to see all the good tennis you can. Study the play of the leading players and strive to copy their strokes. ”
