The National Convention will be held at Milwaukee, August 23-28, in the large Milwaukee Auditorium. The great Auditorium is an ideal meeting place for conventions and has been secured on terms very favorable to the National Association.

This great Auditorium has special advantages that make it attractive as a convention hall. It contains an arena with seating capacity of 10,000, good sized lecture and demonstrating rooms and a first class grill. The manufacturers' exhibits will be placed in the arena, the meetings, demonstrations and lectures in smaller halls and the banquet in the grill.

A contemplated feature of the 1920 Convention is a collection of the best pictures from each of the Amalgamated Associations. Each association will make but one entry of a certain number of pictures selected from the best work of individual members. The pictures will be judged and a trophy valued at $250.00 will be awarded to the exhibit receiving the greatest total of points, this trophy to be won two consecutive years to become the property of the winning association.

Plans are being formulated to secure the best talent available for practical business lectures and demonstrators and to furnish the services of these men to the Amalgamated Associations at practically no expense to them. In this way the National Association will play a helpful part in all convention affairs and by so doing gain strength and prestige for itself.

A big membership drive is planned for the second week in January, and this should have the hearty support of all photographers. A Captain will be selected for every city and town and an announcement of his appointment will soon be sent him along with literature explaining how the drive is to be conducted.

Two prizes of $50.00 each will be awarded, one for the greatest number of memberships secured and one for the highest percentage of memberships in towns of ten or more photographers. Before the beginning of the membership drive every photographer in the country will receive a card setting forth the advantages of membership in the National Association. The drive will close Saturday night at midnight when final reports will be sent to the Secretary. It is to be a live campaign and will mark the initial efforts of President-elect Chas. L. Lewis and the new Board toward making the National Association truly representative of all the photographers in the United States and Canada.

New Method Of Silver Recovery

Silver, at the present time, is hovering around $1.15 an ounce - sometimes higher, and with a safe, clean and unobjectionable method of recovering the silver that goes into your fixing baths, it is certainly as foolish to let solutions containing this precious metal go into the sink as it would be to upset your cash box and refuse to pick up the nickels and dimes.

Previous methods of silver recovery have been either objectionable or impractical, when it has been necessary to recover silver in the studio. First of all, the fumes of sulphureted hydrogen, which are given off when the silver is precipitated as silver sulphide, will fog any photographic material in the vicinity. But even if this were not so, the odor of the fumes is so objectionable that it is necessary to recover the silver away from the studio.

Because of the very small expense of the recovery by this process, however, the fact that it is possible to minimize the amount of sulphureted hydrogen given off, may be of interest. This can be done by neutralizing the hypo solution with caustic soda, testing with litmus to tell when it has become neutral, and then adding an excess of caustic soda in the proportion of 1/2 lb. to the barrel of 50 gallons.

The silver is then precipitated in the usual way by adding about one quart of freshly prepared saturated solution of sulphide of soda. Stir well and allow to stand for at least twenty-four hours. At the end of this time, dip out a graduate of solution, add a small amount of sulphide solution and if the solution remains clear, all the silver has been precipitated .
