SIR KNIGHT W. RYERSON asks to have the rules of the competition published; what the cause of the yellowish color is in the finished negative; the expense of putting up a reasonable amount of toning solution; and the necessary qualifications to belong to the Camera Club. The competition rules were published in the ROUND TABLE for October 6. The yellowish color in the negative is caused by the unused silver salts not being thoroughly dissolved out of the film. If a toning solution is prepared with chloride of gold and sodium with bicarbonate of soda, it will cost 35c. for the chloride of gold and sodium, and 5c. for the bicarbonate of soda. Put the 15 grs. of gold and soda into 7-1/2 oz. of water. This is the stock solution. Put the bicarbonate of soda in water, using just enough water to dissolve it. To make the bath for use, take 3-1/2 oz. of water, and 1/2 oz. of the gold solution. Dip a piece of blue litmus into the solution, and if it does not turn the paper red, add a little more of the gold solution. Add to this a few drops of the bicarbonate of soda, till it turns the litmus-paper back to blue. Mix the bath half an hour before it is needed. To be a member of the Camera Club one must be an amateur photographer. To join the club, send name and address and state your wish to the editor of the Camera Club. SIR KNIGHT WILBUR T. HELM, JUN., and SIR KNIGHT HALL M. CROSSMAN ask whether a pocket-kodak picture can be entered in the prize competition, and which is the best film or plate. The pocket-kodak pictures are under the size allowed, 4 by 5 being the smallest size entered. The Stanley, Carbutt, Cramer, Seed, as well as other standard makes, are all good plates. Eastman and Carbutt films are both fine. [Illustration: IVORY SOAP] GEORGE WASHINGTON By WOODROW WILSON, Ph.D., LL.D. Copiously Illustrated by HOWARD PYLE, HARRY FENN, and Others. Crown 8vo, Cloth, Deckel Edges and Gilt Top, $3.00. What particularly strikes the reader in enjoying Professor Woodrow Wilson's "George Washington" is the way the writer makes that historic figure warm and vital for us.... This stimulating and delightful historical study.... This work of Professor Wilson's must be widely recognized as of great value, because of this grasping of the salient features of Washington's life and character, the features we all want to see.--_Hartford Courant._ We must now be content with a word of praise for its finished literary workmanship, its accurate scholarship, and its high patriotic ideal. We doubt if the career of Washington has ever received worthier treatment at the hands of biographer, historian, or political philosopher.--_Dial_, Chicago.
