and distortion. We decided to print the cov~r to discourage people from try~ng . to find or order the book just to look at it. It's not difficult to imagine where the ~uthors' heads ar:e at when they subtitle a book with its price (that's right, folks, the big 4.50 there is dollars and cents!). But lemon trees, potted palms, and bikinis by the pool have little to do with the facts of life in an energy-starved era, in Canada, of all places! The book itself doesn't provide us with a whole lot of new information ~ut does include some interesting designs for several varying scale and style structures. I'm pleased that they start small with cloches ("the smallest and· ·simplest are just protective covers for young plants which shield them from late spring frosts") and do not ·include a plan for a greenhouse with swimming pool. In fact, their descriptions of the green_houses they do include are pretty practical and down to earth. Which ' leads me to believe that the cover people and the contents people may be two different groups altogether. Nonetheless, they put the book out with that cover and deserve to be criticized for it.

Now, all you frustrated folks out there (myself included) can refer to The Solar Energy Technical Training Directory, which offers the reader Dece111ber 1979 RAIN Page 5 off by charts, figures and molecular formulas. Fish Farming in Your Solar Greenhouse is hardly.remedial reading, but it's not too intimidating to-prohibit a~yo~e's sitting down for an ·evening w~th It. The product of such an evening will be an understanding of how to begi~ to go about fish farming coupled with that g<;>0d feeling of having overcome a previously mystifying body of knowledge. Bill and Jon have managed to translate a lot of technical information into person-to-person English. What chemistry you may not understand at the outset is quickly, competently and simply explained. Besides the basic procedures for designing an a_quacul~ure system, creating a supportive environment (with proper temperature, pH, oxygen and purification of the water) and managing your fish farm, the authors have included an illustrated guide to several suitable aquaculture fish. Each listing describes the basic conditions needed for successfully raising that fish. This is the sort of book that, like the CNT book, carr be utilized by community projects, CAP agencies, and anyone with a yen to experiment. Amity Foundation is a non-profit corporation located in Eugr?ine, Oregon, where they provide community members with the technology they need to live more self-reliant and less energydependent lives. They do research and provide educational programs in the areas ofalternative domestio waste treatment methods, solar design, urban agriculture, and aquaculture. They also operate a tool lending library. over 90 post-secondary institutions conducting solar energy courses in the U.S. Specifically emphasizing solar system fabrication, installation and maintenance courses, the directory's layout is clear and straightforward (really like a college catalog, i.e. giving credits earned, instructor, course coverage, etc.). The technical directory is a "subs~t of ~he National Solar Energy Education Directory released by SERI, which contains information on all solar-related ~ours~s an~ programs." This directory 1s available at $4.95 from: Superint~ndent o_f Documents U.S. Government Printing Office Washington, DC 20402 Stock No. 061-000-00210-3 Both directories are a-good resource for the "solar student." -DW
