that matters little if the light is of proper quality. Admirable views may be made in a rain storm - if the sun shines.

324. In conclusion, a word as to the dark-tent. Any light enclosure set at a proper height will do, large enough to accommodate the hands during the necessary manipulations of the plate. A light frame of wood, with non-actinic cloth to form the body, is all that is needed. The form and size must suit your purpose. Have sleeves added for the insertion of the arms, and a peep-hole to see what you are doing inside is also essential. Mr. Robinson's excellent Pictorial Effect in Photography elaborates this subject to a charming degree, and should be consulted by all landscape lovers.

324. To dye cloth for tents, dark-room windows, etc.. make the following solutions:

No.1.- Acetate of Lead,..................

1 ounce.

Water,..................

1 quart.

No.2. - Bichromate of Potash,..................

1 ounce.

Water,..................

1 quart.

Dip the cloth in No. 1, drain a little (but do not wring it), and dip in No. 2; it takes the color instantly. Rinse slightly, and repeat two or three times. If the cloth is new, it should be washed thoroughly, to remove the dressing, before dyeing. Wash or rinse out all loose color and hang in the sun to dry. This will give a deep, rich lemon color, composed of chrome-yellow, and perfectly non-actinic. - J. L. Gihon.
