Very serviceable brackets for a towel roller can be made by using ordinary wire clothes hooks, as shown in the illustration. The roller is made of wood and two nails with their heads cut off, one in each end, form bearings to turn in the ends of the hooks. When it is desired to remove the roller, the hooks are sprung apart enough to allow it to drop out. - Contributed by Hugh Carmichael, West Lorne, Ont.
