1969-1970. Teale and Borland provide comments for Frank Graham's 1970 book Since Silent Spring, which told the story of Carson's writing Silent Spring, the controversy it engendered, and the continuation of her cause in the intervening years (as, despite Carson's success, DDT was not fully banned until 1972). Borland, in a typed letter signed, both praises Graham's book and recounts his own battle against DDT that he was waging as Carson wrote. Teale (who had also written about DDT prior to Silent Spring) in a typed postcard signed praises Graham's book and also Carson, whom he calls "a remarkable woman." Both items are stapled to retained copies of thanks from the publisher; the Borland is folded for mailing; else the lot is fine. Borland and Teale were both recipients of the John Burroughs Medal for a distinguished book of nature writing, as was Rachel Carson. [#036681] SOLD
