Page 12 RAIN October 1978 Assembly of the MINI-MISTER is as follows : a. Cement the two caps (2 & 3) to the tube with ABS cement. b. Drill a hole in the clean-out (4) to receive the insert (6). Place the insert in the hole and fasten the nut (7). Push the bicycle valve (8) snug onto the insert. c. Screw the completed assembly into one end of the reservoir. d. Drill a hole in the second clean-out (S)to receive the insert (9). Place the insert in the hole and fasten the nut (10). Push the end of the hose (13) over the insert and tighten the hose clamp (11) over the hose. e. Insert the other end of the hose onto the control valve (14) and tighten a hose clamp (12) over the hose. f. Screw the adapter assembly (15,16) into the control valve (14). g. Screw the nozzle (17) into the adapter assembly. h. Now screw the entire assembly into the other end of the reservoir.

There is a substantial energy tradeoff, however, both to operate the pump and for heating to offset the considerable evaporative cooling caused by the atomizing. In water-rich areas it's hardly worth considering. Hot, arid climates are a different story. The Minimum Cost Housing Group, well-known for their path-breaking Stop the Five-Gallon Flush, is carrying on development of low cost mist showers, with the ultimate aim of avoiding the need for the intricate and expensive plumbing connected with our present bathing habits. The Do-It-Yourself lt is possible to build a small portable mist shower for well under ten dollars.

It would be possible to utilize a Volkswagen windshield washer reservoir, which already has a built-in pressure valve, but as a car accessory this is quite expensive (about $20 for the reservoir alone). Instead we have developed a design that uses ABS (or PVC, though this costs more) plastic tubing and closures. The main component is a piece of Step Two Pressurize the reservoir; either manually with a foot-pump (less work) or a handoperated pump, or mechanically from a garage air pump, pressurized cannister or electric pump. The pressure should be 1-2 atmospheres(J5-JOpsi). 75 mm (3") diameter tubing. This forms the reservoir whose capacity will depend on the length of the tube: 50 cm (20") contains about 2.3 litres (0.5 gallons) Stl'P Three With reservoir in vl'rticaJ posit.Ion you nrP now rf'ndy tn showc•r.

Here's a nice reminder for our noses-the art of perfumary-the nature of scent, ingredients of perfume, extracting the scents of flowers, roots, etc., and how to use them to make incense, scented candles, perfume and other nice-smelling things. -TB of water. Music of the Whole Earth, David Reck, 1977, $9.95 from: Charles Scribner's Sons 597 Fifth Avenue New York, NY 10017 Every time I hear the typical "Western" explanations of music-confidently expounding octaves and notes and such things as THE structure of music, I remember the sliding sounds of trombone and singing and waterfalls, and see us again projecting our accidents of our own musical history and ignorance as . the whole universe of the possible. This book is a delightful exception. It takes us about as far through an understanding of our planet's music as is possible .
