W. L. DUBOIS, Urbana, Ohio.--You might lighten your racket by scraping it with glass or sand-paper, or by hollowing out the handle. Don't soak it. You will find it more satisfactory in the end to buy another, or to trade your own off for a lighter one. K. M. TOWNER, Asbury Park, New Jersey.--A correct diagram of _Defender_ is not to be had. Some of the yachting papers published approximately correct diagrams at the time of the recent races. There will be an article on the construction of model yachts in the volume of HARPER'S ROUND TABLE, which begins with this issue. THE GRADUATE. [Illustration: THE CAMERA CLUB.] Any questions in regard to photograph matters will be willingly answered by the Editor of this column, and we should be glad to hear from any of our club who can make helpful suggestions. OUR PRIZE OFFER. Our prize offer has brought many queries in regard to the rules of the competition, the printing, mounting, and marking of the pictures, the style of picture required, etc. Though the rules and requirements were made as plain and concise as possible, we are quite willing to go more into detail and to answer any question which will aid our Camera Club to make this competition the best we have yet conducted. The competition "open to all amateurs" seems to call forth the most queries. "Can any one under eighteen take part in it?" "Can an amateur under eighteen send pictures to both contests?" "Must an adult amateur be a member of the Order?" "May an amateur under eighteen who wishes to take part in both competitions send the same picture to each?" are some of the questions asked. The prize offer "open to all amateurs" is, as stated in the circular, open to all amateurs who desire to take part in it, _without regard to age limit_. This, of course, admits any member of the club under eighteen, and any member under eighteen may take part in both competitions. Any adult amateur who wishes to enter the competition may become a "Patron" of the Order by simply sending name and address on a postal to HARPER'S ROUND TABLE. While there is no condition which would prevent an amateur sending the same picture to both competitions, it is expected that he or she will not do so, as it would be hardly fair to allow a picture to win a prize in both competitions, provided it was the best of its class, for both are, of course, under the same rules, and have the same classes. One correspondent wishes to know if he may send bromide prints. Referring to Rule V, he will see that any printing process may be used, with the exception of the blue-print. This is no reflection on the blue-print process, which is sometimes preferable for some pictures; but blue prints are usually excluded from photographic competitions, as it is harder to judge the real merits of a picture from a blue print, and they do not reproduce as well as those in black and white.
