Cummings brought me to your mag. He is keeping me there. So hold on to him. But, please tell him to forget all about time and probe the mysteries of the infinitely large and small, of interplanetary space, of future civilization and future warfare.--Dale Mullen, 611 West Fifth, Topeka, Kansas. _The Effects of Cannabis_ Dear Editor: I have sold magazines, written for magazines, and, now that I have just concluded your April issue, I am editing one--for myself. Specifically, one story, "Four Miles Within." Inside of a radium mine! Chased by an amoeboid body! Ooh! Several years ago when I was a clinical chemist in hospital service, the Roentgenologist, also a young chap, and a surgical nurse and myself were so badly burned with three grains of the substance enclosed in a lead capsule that we were crippled for nearly a month. [No fair. Your experience was with pure radium. It was only radium ore in the story.--_Ed._] Imagine being four miles inside of the earth exposed to radium "ore"! And chased and pursued by a gigantic amoeba! Oh, oh! That must have been my pet mother-of-vinegar that escaped. She was hard to herd. She took after my dad's pet fish which fell through a crack in a bridge and was drowned. In passing, it is interesting to note that persons can vanish "into" a plane surface; say, "into" a fifth dimension. My instructor in trig. must have been all wet. And Dr. Bird catches a man withdrawing "menthium" from human brains with a "needle," without the use of either x-ray or a trephine! And then low forms of life such as crabs and alligators with very highly developed scientific knowledge! A few issues ago octopi were in the lead! And those "space" ships! Mars must be an interesting spot. And those Martians! Sometimes they are ant-like, and other times worms, and again human freaks! (I still prefer the silver-green messenger I saw on the stage twenty years ago. He was a gentleman and a scholar and no one yet has improved upon him.) And those radio waves that can vibrate matter in a straight line! One Jackson Gee vibrates it in two straight lines. (Rather funny at that.) And people disappear into an atom by taking pellets! They take the pellets into their system and that shrinks or expands them. How does the author calculate that in "Beyond The Vanishing Point"? The pellets must contain cannabis indica (hashish) I guess. Once upon a time I was suffering from an acute attack of colic and was obliged to use an anti-spasmodic. I took cannabis, and in the delirium that followed I shrunk small enough to walk into a mouse-hole into which I had seen a mouse disappear a few hours previous. The mouse was there and looked like an elephant. I awoke in a sweat.
