From the introduction by Floating Bear editor Diane di Prima to the 1973 cloth edition collection of Floating Bear: A Newsletter published by Laurence McGilvery, as reprinted in the Beat Down to Your Soul anthology (ed. Ann Charters):
“‘Tear Gas’ by Michael McClure in Number 37 [March-July 1969] came my way in a kind of interesting way. There was an issue of The Realist, Paul Krassner’s magazine out of New York, that was devoted completely to the Diggers [No. 81/August 1968], and distributed free in San Francisco. And then there was a lot of leftover material that didn’t get into it, most of it unsigned. This leftover stuff was sent to my house in San Francisco by Emmett Grogan, so that Ron Thelin could get hold of it. Ron was one of the editors of the Oracle, but the Oracle had folded by then, and Ron wasn’t doing anything with the manuscript, so he left it with me. I found the piece by Michael, and stuck it in the last Bear…
“I edited Number 37 in San Francisco and deliberately aimed for a West Coast feeling. A whole bunch of the last issue, Number 37. was stamped ‘free’ and left at the Third Eye bookstore on Haight Street because I thought the people of the City of San Francisco should have it. I also left a handful at Cody’s and Moe’s in Berkeley. It was definitely a West Coast issue. The whole free city thing was going strong then, the Diggers and so on, and we wanted to have plenty of copies for everyone.”
