Materials Required:—

Two narrow strips of thin, soft wood, a stick for a holder, a screw, penknife, gimlet.

This is a wooden mill and it requires some care and skill to make it. It can easily be made with a penknife out of two pieces of thin, soft wood. First you must cut a neat socket across each piece of wood in the center, halfway through its thickness. The socket must be exactly the same width as your piece of wood, so that when you set each piece socket to socket they fit exactly. Now with an awl or pricker make a neat hole in the center of the two pieces when they are fitted together. Next you must shave away with your penknife the right-hand edge of each of the "arms" or "sails" of your windmill, graduating the shaving evenly from the left-hand edge, where it is thick, to a fine blade at the right-hand edge. Now fit together the two halves and put a nail through the hole and fasten it into the end of a stick. If the nail is apt to split the stick you can put a reel on to the end of it and fix the nail into the stick through the hole of the reel. It is a very good thing to put your nail through a large glass bead between the windmill and the stick.
