I'm accepting your kind invitation to come over to "The Readers' Corner" and express my opinion of your magazine. I like it immensely. I read all the Science Fiction I can, and your magazine heads my list. I think the serial "The Pirate Planet," is as interesting a story as any I've read. Astounding Stories improves with every issue.--Dorothea Cutler, P.O. Box 122, Mesa, Arizona. _Two Problems_ Dear Editor: My last letter was entirely commendatory, but this time I am losing the full force of my critical powers (?) on the story "Marooned Under the Sea," by Paul Ernst. In this story the characters descend to the depths of the ocean by means of a large glass sphere. Mr. Ernst mentions the terrific strain on the supporting cable caused by the weight of the sphere. He quite overlooks the fact that it would float. As a matter of fact the sphere, not counting its contents, weighs about 3,511,520 lbs.--less than an equal amount of water. Hard to believe, but true, as the figures show. The formula for the volume of a sphere is V equals pi 1/2 diameter cubed. It is a pretty little problem. Also, there was no need to break the helmets of the Quabos, since the hoses could be cut with an ax. However, it was a fine story. Let's have more like it. Here is another problem. X equals wonderful. Y equals superb. Z equals marvelous. XYZ equals Astounding Stories. Yes? No? You are getting many requests to change your size. Don't do it. As it is now, it is just the size to carry conveniently, or put in your pocket. It is easier to read, too. Don't change your grade of paper, either. Glazed paper is hard on the eyes. I join my fervent prayers to those who wish the edges cut smooth, however. It is hard to turn to the page you want, with the deckle edge you now have. "Earth, the Marauder" was wonderful. Too bad it wasn't longer. "The Pirate Planet" is fine. Dr. Bird is keeping up the good work. Some of his stories are a bit far-fetched, but that is no drawback. I notice that some authors repeat themselves. I read "Brigands of the Moon," by Cummings, and also his story, "Tarrano the Conqueror." The weapons used in both stories are identical--Hugh M.
