To close, let me repeat that I am not arguing that such a layer exists. I do not believe that it does and I do believe that my generation will probably see the first interplanetary expedition start and possibly see the first interplanetary trip succeed. I do, however, contend that the science in my stories is accurate until it transcends the boundaries of present day knowledge and ceases to be science and becomes "super-science," and that my super-science is developed in a logical manner from science and that nothing in present knowledge makes the existence of such a layer impossible--S. P. Meek. Capt. Ord. Dept., U. S. A. _Likes Long Novelettes_ Dear Editor: I have just finished reading the August issue of your magazine. I am going to rate the different stories in per cents. 100% means excellent; 75% fairly good; 50% passable; 25% just an ordinary story. I give "Marooned Under The Sea," by Paul Ernst, 100%; 75% for "The Attack From Space," by Captain S. P. Meek. "The Problem in Communication," by Miles J. Breuer, M. D. and "Jetta of the Lowlands," by Ray Cummings; 50% for "The Murder Machine," by Hugh B. Cave and "Earth, The Marauder," by Arthur J. Burks; 25% for "The Terrible Tentacles of L-472," by Sewell Peaslee Wright. I am happy to say that since I have been reading your magazine, I have induced at least ten of my friends to be constant readers of this magazine. I like the long novelettes much better than continued novels, and hope that in the future we will get bigger and better novelettes.--Leonard Estrin, 1145 Morrison Ave., Bronx, N. Y. _Hasn't Decided_ Dear Editor: Move over, you old-timers, and let a newcomer say something. A few months ago I didn't read any Science Fiction. Now I read it all. I haven't decided yet which magazine I like best. I was a little disappointed when you didn't have another story in the September copy by R. P. Starzl, who wrote "Planet of Dread." I thought you would hold on to a good author when you find one. I would also like another story by the fellow who wrote the serial "Murder Madness." I like short stories best. That idea of a mechanical nirvana in Miles J. Breuer's story was good. "Jetta of the Lowlands?" Opinion reserved. I like the action of the story, but I hate a hero who is always bragging about himself. Don't think I'm complaining, but nothing is perfect. Why not try to get a story of A. Merritt's, or Ralph Milne Farley's?--A. Dougherty, 327 North Prairie Ave., Sioux Falls, So. Dak. _Announcement_ Dear Editor: May I enter "The Readers' Corner" to announce that a branch of The Scienceers has recently been formed in Clearwater, Florida, by a group of Science Fiction enthusiasts? We have a library of 175 Science Fiction magazines, including a complete file of Astounding Stories to date. We hold weekly meetings at which scientific topics are discussed, and current Science Fiction stories commented upon.
