Walnut Shell Boats
To make a boat from a walnut shell, you scoop out the half shell and cut a piece of cardboard of a size to cover the top. Through the middle of this piece of cardboard you thrust a match, and then, dropping a little sealing-wax into the bottom of the shell, and putting some round the edge, you fix the match and the cardboard to it. A sail is made by cutting out a square of paper and fastening it to the match by means of two holes; but the boat will swim much better without it.
