DUCK
The parts for this fowl are sawed out of 1/4" stock. The edges should be sawed square and to line, and may be made smooth and slightly rounded by filing and sand-papering.
The two feet should be made alike and held together when the hole for the nail is drilled thru them. The bottom of the feet will then be on the same level, and the duck will stand upright. Put a fine 1" nail thru one foot, drive it thru the body, at the proper place, and press it thru the other foot.
With round-nose pliers, bend the end of the nail around so the end will point toward the wood ([Fig. 5]). Place the head of the nail against a block of iron, and with the hammer drive the point of the nail into the foot. The joint should be firm and movable so the duck will stand at different postures.
