The Life and Letters of John Burroughs (with signed ALS from Barrus)

NY: Houghton Mifflin, 1925. First edition. Hardcover. Very good/Good. A biography of John Burroughs in two volumes. Neither is signed, but laid into volume one is a one-page autographed letter signed (ALS) from Clara Barrus, John Burrough's close companion and the steward of his legacy as first assistant and then literary executor. It's addressed to the author of an article, "Burroughs, Unofficial Ambassador," that appeared in The Christian Science Monitor, presumably in 1928 the year the letter was written. She writes "I think Burroughs himself would have enjoyed it." Googling doesn't turn up the article, but surely it could be found; the author is apparently anonymous, though Barrus leads with initials: "J.P.S.E." (another hand has then written "= O.S." . . . a mystery). On letterhead reading "Woodchuck Lodge, Roxbury-in-the-Catskills" the home of Burroughs, the missive finishes: " As the biographer of J.B., many things written about him drift to me, & many of them are inaccurate and, in other ways, irritating, so that it is a particular pleasure to come upon your article, every sentence of which I enjoyed." The letter is 6 x 9, very good, at one time folded four-ways, but now creased just across the middle. The upper left corner is torn away, but a shallow loss. The books are very good plus with only some light foxing to endpapers and on text block faces, interior pages clean and the dark green buckram boards excellent with just some light rubbing to corners.  One or two marginal notes pencil. Each volume with a frontispiece photos of Burroughs, first young then distinguished in white beard. Both in good jackets with only printing on their spines, each with some chipping and tears, including a tear all the the way across the front panel of Volume Two's jacket.  A nice letter from Barrus.
