Marian E. P. Greene, Jamacha, Cal., writes: "A Swiss friend, much interested in autograph-collecting, has sent me one of her 'traders'--an autograph of Emile Zola--with the request that I exchange it for some well-known American or English writer. I also have the autograph of Princess Victoria of Schleswig-Holstein, generally known as Princess Christian. This I will be glad to trade for an American autograph, or will send it with Zola's in exchange for a very good one. I would much like to have the ROUND TABLE dated December 25, 1895, and will send ten cents in stamps to any Knight or Lady who can procure it for me. If a Lady of the Round Table has passed her eighteenth birthday, can she still write to the TABLE from time to time, and send questions to be answered, or must she give up this privilege?" She need not give up the privilege. The TABLE is glad to receive morsels descriptive of interesting places, people, and things. An Orange subscriber asks where he can see pictures of the different ships of our navy. In HARPER'S WEEKLY, files of which you will find in your local library. If you wish to possess them, you can procure back numbers of the WEEKLY. Consult the file to see what numbers you desire. In the WEEKLY you will find not only pictures of all our naval ships, but pictures of some of the larger ones in several positions.--"A. H. S." asks: "If a picture takes a prize in your Camera Club Competition and is printed in your paper, are you the holder of a copyright on said picture? And also if it may be submitted for printing in another journal at some future time?" Each issue of most periodicals is copyrighted. That copyright covers everything in the issue. Where a photograph has been reproduced in a periodical, whether HARPER'S ROUND TABLE or some other, it is best to ask the publishers' permission about using it again. That permission can generally be obtained, or at least a plate purchased. Of course one would hardly enter a prize-picture in another prize competition. That might be fair, but one cannot afford to appear over-greedy. Richard Stark, Jun., sends us the following:
