A Screen used in Photographing Animals

Department of Dairy Husbandry, Agricultural Experiment Station, Wooster, Ohio

ABSTRACT

About six years ago the writer planned and constructed the device here described, in which to photograph cattle used in experiments. A considerable number of persons have been interested in it and the suggestion has been made that a description of it be published in some scientific journal. The writer finds it a very convenient piece of apparatus and this description is presented with the hope that it may be of use to others.

The one shown in the cuts consists of a screen, a platform and a background. The screen is constructed as follows: A rectangular frame 9 by 12 feet is made of 2-inch pipe. Holes large enough for a no. 9 wire are drilled through the frame at intervals of 6 inches. Vertical and horizontal wires are passed through these holes and stretched to form a screen with 6 inches mesh. It is important that the sides and ends of the frame be held rigidly while the wires are being stretched and secured.
