Preliminary work resulted in the pouring of the foundation and the gathering of the required materials. The actual construc- ~ion of the greenhouse took place durmg-the workshop weekend in the fashion of an old barn-raising. This manual was relied upon heavily 'in the design and construction phases. So I can tell you from first-hand knowledge that it works. The Solar Greenhouse Guide has the usual sections on heat loss calculations and sun path charts, but what makes it stand out is the step-by-step constn!ction explanation with appropriate illustrations. Sample architectural . drawi?gs, materials and tools list, plus a sect10n on food production provides everything else you need to know. The only additional information that might be necessary is the bas~c carpentry . skills of one or two friends. -PC Solar Energy for Lane County, edited by Joyce Theios, 1978, 32 pp., free from: • .

Tbe illustration accompanying the text is very similar to a currently marketed solar oven.
