No doubt many amateur photographers are troubled about drying films and to keep from curling. The problem may be solved in the following way:
Make a rectangular frame out of pine wood, 1/4 by 1/2 in., as shown in the sketch. It is made a little wider and a little shorter than the film to be dried. This will allow the end of the film to be turned over at each end of the frame and fastened with push pins. Do not stretch the film when putting it on the frame as it shrinks in drying. The film will dry quicker and will be flat when dried by using this frame. --Contributed by Elmer H. Flehr, Ironton, Ohio.
Having made some photograph prints at one time that I wanted to dry without the edges curling, I took an ordinary tin can and a strip of clean cotton cloth, as wide as the can was long, and wound it one turn around the can and then placed the prints, one after the other, while they were damp, on the cloth, face downward, and proceeded to roll the cloth and prints quite close on the can. I then pinned the end of the cloth to keep it from unwinding and set the whole in a draft for drying. The curvature of the can just about counteracted the tendency of the coating on the paper to make the prints curl and when they were thoroughly dried and removed they remained nice and flat. --Contributed by W.

The drying of photographic film in full lengths without scratching or curling is quite difficult. Various devices are used to keep the film straight, and push pins or thumb tacks are supplied with almost all of . The illustration shows a simple and inexpensive device constructed of common wood clothespins without any metal pins to come in contact with the film and cause rust streaks. A pair of pins are fastened at each end of the film by pushing one pin over the other which in turn is clamped on the film. A string tied to the heads of one pair of pins provides a way to hang the whole on a nail. The lower pair of pins makes a weight to keep the film straight. --Contributed by J.

A novel idea for drying photo postal cards comes from a French magazine. The drying of the cards takes a long time on account of their thickness, but may be hastened by using corrugated paper for packing bottles as a drying stand. Curve the cards, printed side up, and place the ends between two corrugations at a convenient distance apart. They will thus be held firmly while the air can circulate freely all around .

Photograph prints can be kept from curling when dry, by giving the same treatment as was once used on films. Immerse for 5 minutes in a bath made by adding 14 oz. of glycerine to 16 oz. of water.
