Stovers, <br>

I found the message below about air quality to be extremely
interesting. It comes from Kirk Smith's Google Group, which is
"stove" (without the final s in our Stoves Listserv.) The address
is at the end if you want to subscribe to it. (only a few messages
per month, without discussion back and forth.)<br>
