C ) Wood Connections, 1975, $4.50 from: The Timber Framing Book, Stewart Elliott and Eugene Wallas, 1977, $9.95 from: BUILDING Island Hot Baths Box 4676, Rolling Bay Bainbridge Island, WA 98110 These folks have available the only wood-fired Japanese bath heaters we've been able to find in the U.S. Expensive ($325), bµt they look good- sturdy copper construction and complete with tub fittings and connecting pipes. Boiler burns coal, wood or charcoal. We're still looking for other types-submersible ones that fit inside the tub, ones that operate on other fuels, etc. Know of any? -TB Robin Hood Publications Berkeley, CA Found this in a small store in Berkeley, but can't find an address for the publisher. Joints-page after page of jointsfrom Europe, Asia and America. A builder's delight. Gives some explanation of some of the joints, but it would still be useful to have more information on relative strengths and special qualities and uses of various joints. Want to do it? -TB Housesrniths Press P.O. Box 416 York, ME 03909 There's a special good feeling in building when a beam sets down into a mortised post with a solid "thunk" and everything stands there solid and true. That special feeling carries over to most people who use the building-and it never comes from "2x4" construction. This book is about timber framing based on traditional New England housesdone by people who do it well-todayand make a good living by it. Good. how-to. -TB
