To the real estate editor: Re a recent query concerning a compost-pile heat source, Mother Earth News, No. 62, had an article on the subject. Incidentally, this magazine prints all sorts of articles on solar heat and allied subjects.Most of the queries you get in your column appear to have been discussed therein.
I enjoy your column, although your advice to contact government agencies for information does not agree with my experiences in that direction. David Birnbaum Chillicothe, Ohio
