When making a chicken house recently I had forgotten to procure hinges. When searching the "junk" box I found some little metal brackets such as used for holding spring roller shades. Attaching these as shown, I made a good substitute hinge. A pair of the brackets having no slots were selected. A 2 1/2-in. wire nail with a washer was placed in the hole and driven into the top of the door, 1 in. from its back edge. The other bracket was placed on the bottom of the door in a similar manner. The door was placed in an open position and the prongs of the brackets were nailed to the door post. The bottom bracket may also be nailed to the floor and the top one to the lintel. - Contributed by Robert Smith, E. Burnaby, B. C.
