Cotton Duck Windows
The door, for the use of the attendant, is in the front of the House, being two feet wide and the full height of the inside of the building. On either side of the door, hanging by hinges from the plates, are two windows 45 × 27 inches. These are covered with a medium weight cotton duck, and open outward. A device which carries a long hook readily allows them to be fastened so as to practically form an awning, which materially assists in maintaining a cool condition inside the House during the Summer. Two doors for the use of the birds are placed on each side of the main door, and are fitted with slides. On the inside of the window openings one inch wire mesh is securely nailed, preventing the birds from flying out, and also keeping night prowlers from going in. Over the outside of the window frames also inch wire mesh is nailed. The main reason for this wiring of the outside is to prevent the birds, as they develop and fly up on top of the Colony House, from breaking through the canvas.
From the detailed drawings which will be found at the end of the Book, and the [photograph] of the Colony House, a very clear idea is given of its construction.
