In my collection are the manuscripts of such stories as "West of the Earth" (renamed "In Martian Depths") by Juve, Miss Long's "The Last Man" ("Omega"), "The Egg from the Lost Planet" ("Girl from Mars," by Breuer-Williamson), Skidmore's "Romance of Posi and Nega," "Lancer in the Crystal" ...

"The Golden Bough," by Dr. Keller, Ed Earl Repp's "Metal World", Bob Olsen's "My Martian Sweetheart", pages from different Edmond Hamilton stories, and others, plus the entire serial by C. Willard Diffin, "Two Thousand Miles Below." I have, in addition, a translation into French of David H. Keller's "Stenographer's Hands," which originally appeared in _Amazing Stories Quarterly_. The French version is known as "Les mains et la machine." Also, there are four letter files and a large cabinet--all chock full of correspondence from authors and fans. There is one portion of my collection yet to be described: the scientifilms. In a large box are advertisements, press-sheets, reviews, write-ups, publicity copy, photos, "cuts," and all similar material from dozens of movie magazines, newspapers, other periodicals, film companies and all parts of the world on the scientific from long years ago up to even those to be produced in the future. The amount of material covered in this file is impossible to describe. (In the installments Mr. Ackerman tells about his scientifilm "stills".) Birkett's Twelfth Corpse by August W. Derleth The wall of hate that stood between the two old rivermen, Fred Birkett and Hank Blum, had grown from a strange and gruesome rivalry--the finding of dead bodies of persons drowned in the Wisconsin River at Sac Prairie. At the time of the tragic drowning of Bud Enders, the rivermen were tied--each had found eleven bodies in the past forty years. It was said by each of them, and repeated in Sac Prairie, that Bud Enders' body would decide the contest. The sympathy of Sac Prairie was with Birkett, a kindly old man in contrast to the sullen surliness of Blum, who was, too, somewhat younger. Birkett had always joked about his odd luck at finding bodies in the river, and still looked upon his almost uncanny way of knowing where the bodies had been taken by the swift current as more amusing than not. But Blum had brooded upon his rival's luck ever since Birkett had earned a five-hundred dollar reward for finding the corpse of a young student who had fallen into the Wisconsin while drunk, almost a decade before. Now Blum made no effort to conceal his violent hatred for Birkett, nor could Birkett keep down his dislike for his rival.
