the heavy end boards from the top corner to a point 6 inches lower 
at the rear. Remove the top rear board to the level. Saw enough 
of the match boards a proper length, so that they will entirely cover 
this top opening and allow for small eaves. Fasten these boards 
together with cleats, making the lower cleat fit loosely against the 
. rear side of the box. This will hold the cover in place and allow 
it to be removed at will. Make an opening in the lower front 
side in which to place a 7 inch X 9 inch window glass. Fasten 
grooved guides below and above this opening to fit the window 
sash and allow it to be pushed open or shut. Bore four 1 inch 
holes in the front side just above the window. Make a convenient 
sized frame run and cover with fine mesh wire or cleats.

Object. To make a force feed-hopper. 
Materials. Hammer, crosscut and rip saws, pair of wire clip- 
pers, 2 pair light hinges, 1 pound 8d. nails, 2 hooks and eyes, 15 
feet of No. 8 wire, 1 piece tin 6 inches wide and 5 feet long, 50 
feet square-planed and matched lumber. 
Directions. Square the ends of the 10 inch board and saw 
through the middle at a 45° angle to give the bevel at the top. 
Fasten cleats on these ends extending from 1 inch inside the lower 
corner of the beveled end to within 3 inches of the bottom end and 
6 inches of the front. Lay these ends on the floor 5 feet apart, 
front edge up. In this position nail the front boards to these 
cleats. Next, fasten a 5 inch board across the front at the bottom. 
Drive pieces of wire 8 inches long, ¢ inch into this bottom board 
2 inches apart. Bend these wires back against the body of the 
hopper and fasten with a small staple. A door to close the fowls 
away from the feed can now be made the size of this area and 
hinged above the wires. Next, nail a board across the top at 
the back and hinge a door to this board, covering the rest of the 
top (Fig. 139). The hopper is now ready to be hooked to the side
