F. MACQUAIDE, 46 Mechlin St., Germantown, Pa., says that she has a number of 4-by-5 views which she would like to sell. If any of the Camera Club wish to purchase, a letter sent to address given will bring list of subjects and price of same. Our correspondent also wishes to buy a second-hand No. 2 Bull's-Eye camera. B. COVER, 713 Avenue W, Ashland, Wis., has a 5-by-8 Anthony view camera, with three double plate-holders, which he will sell cheap, or exchange for a 4-by-5 camera. WILLIAM O. WICKMAN, Great Barrington, Mass., wishes to purchase a picture of the White House, Washington, D.C. Would like either 4 by 5 or 5 by 8. JOHN G. VOLKES, 324-1/2 Eighth St., New York city, would like to correspond with members of the Camera Club on photographic subjects. CLAUDE A. WOLFE, 1701 Diamond St., Philadelphia, would like to exchange a print of the State Capitol building of Tennessee for one of the Capitol buildings of New York, Massachusetts, and Maine; he also asks if any member has a good view camera which he wishes to sell, or exchange for a bicycle and a 5-by-7 Premo camera with five plate-holders. B. A. PORTER, 212 Tulip Ave., Brooklyn, N.Y., has views of Strong, Me., and of Brooklyn and New York, which he would like to exchange for views of other localities. Our correspondent asks those members sending prints to use an extra fixing-bath in toning the prints, as he is making a collection, and many of the prints fade after a while. For those who do not care to exchange, and who would like good views of the places named, he will sell unmounted views for 10c. each. DUDLEY GREGG, Hogsett Military Academy, Danville, Ky., asks if any member of the Camera Club has a pocket-kodak which he would like to sell. WILLIAM S. JOHNSON asks what is sel d'or; a good formula for mounting-paste; a formula for metol developer; if hydrochloric and muriatic acids are the same; and where rubber finger-tips may be purchased. Sel d'or is a salt of perchloride of gold and hyposulphite of soda. Starch paste made by mixing with cold water and then boiling until of the proper consistency makes an excellent paste for mounting photographs. It will not keep, but must be made fresh when wanted. A good formula for metol developer is: Metol, 30 grs.; sodium sulphite crystals, 180 grs.; carbonate of potassium, 90 grs.; and water, 4 oz. Hydrochloric and muriatic acid are the same. Dealers in photographic supplies sell rubber finger-tips. Three finger-tips cost 15c.
