In Fig. 6 some suggestions for wooden vanes are shown that can be followed with the scroll saw and jackknife or a compass saw and carving chisels. These vanes can be made in almost any size that will not be out of proportion to the building or pole they are to be mounted on.

The fish is cut from wood five-eighths of an inch thick, and all around the edges the wood is bevelled so as to give the fish a rounded effect. The fish is balanced on the edge of a piece of wood to determine where the rod will pass through it; then with a quarter-inch bit the hole is carefully bored through from top to bottom. The compass-point letters can be made from sheet tin and supported on two cross sticks and a stout wire hoop from twelve to fifteen inches in diameter.

The lady with the parasol is cut from wood half an inch in thickness. She is fifteen inches high and twelve inches wide across the bottom of the skirt. From the shoes to the hat, a quarter-inch hole is bored entirely through the body, but if this be found too difficult, a staple at the top and bottom will answer instead. Through these staples the rod will pass.

The squirrel is made in the same manner as the lady, and either balanced on the rod which passes through the body or by means of staples driven at one side. A ring and washer should be provided on the rod for the bottom of the vane to rest on, as there would be too much friction if the vane rested on the top end of the pole into which the rod is driven.

The bird vane is cut out and balanced the same as the fish, and the modelling may be carved in the wood or painted, to give shape and character to the vane. Otherwise it would be but a blank piece of thin board cut in the shape of the outline.

In all of these vanes it is necessary, of course, to have the greatest overhang on the side opposite to that facing the wind, otherwise they would not indicate properly.
