���A Completely Equipped Portable Cabinet for the Photographer
THE case shown is 24 in. high, 30 in, long and 6 in. thick. It may, of course, be made any size, but this one can be placed behind a door or in a closet
out of the way, and is large enough so that the printing box compartment will accom- modate a 5 by 7-in, size or smaller. The capacity of the case is sur- prising. On the upper left door are the scales, which can be tilted to bring them level, a drop- ping glass, stirring rod, palette and tweezers. On the upper half are eight 4 by 5-in. holders and an exposure meter. On the upper center shelf is room for all sorts of sen- sitized paper up to 12 by 14 in. in size for enlarging, and the latest negatives. On the right side the shelves occupy only half the width, the remainder being placed on the door.
In the case will be found 1 lb. of sodium carbonate, '^ ■> lb. of sodium sulphite, 1 oz. potassium metal-bisul- phite, 1 bottle retouching varnish, two 3 oz. bottles of toner, 1 box of potas- sium citrate, 1 box potassium bromide, 1 box of copper sulphate, 1 box pow- dered alum, 1 box citric acid, 1 box chrome alum, and 1 glass funnel. In the bottom section is a book of for- mulas. On the door is 1 bottle each of 10 per cent bromide of potassium, i)yro, aerol, and amidol, 1 box hydroquinone, 1 box of potassium ferricyanide, a pack of filter paper, 1 box of opaque, 1 box of sepia toner, 1 box of green toner, 1 box of intensifier and a rack for masks at the bottom.
When the two doors shown in the
��The cabinet when closed can be carried easily
��lower central portion are closed, the trays, trimming board and blotting pad may be stored therein. When these doors are lowered they at once become available for holding the various trays in development. The door in the fore- ground is covered with rubber. The lower central portion is also provided with a folding rack for glass plates and with clips for holding films while drying, which keeps them out of the dust.
At the lower left is the printing box, the inside of which is painted red and provided with a curtain of ruby fabric, shown partly raised from the bottom. This runs in grooves and is held up at the top by a spring, thus closing out all white light, making a fine dark lan- tern.
What appear to be two narrow drawers above the lamp is the printing frame, the lower half slides out only half way and the top part the rest of the way, so that a negative may be inserted and removed easily. The red light reflected from the white enamel door below, throwing the rays up through the nega- tive, makes placing the paper an easy matter. The corner shown partly raised is fastened to the frame so that when the frame is pushed back in the case it is forced down in close contact with the paper and negative by two flat

springs placed beneath the compartment housing the scales. This door is also provided with a spring to open it, as shown, as it is withdrawn from the case. This, of course, stops the printing.
The lamp shown is for enlarging; the one for printing is back of the curtain
