What prompted me to write this letter was an article, "A Robot Chemist," published in your March, 1931, issue. In the article it states that a mechanical robot performed several experiments without human supervision. But, I am sorry to say, I disagree. Nothing is automatic. Foolishly, after perfecting anything that performs its work afterwards by itself, man calls it an automaton. But it is not! Did he not have to work and slave hour after hour, day after day and month after month to perfect it? He did! Ever since man became civilized he has deceived himself by calling, for instance, machinery in a factory, automatons. The quest for automatic machinery is as hopeless as the quest for perpetual motion!

What is my idea of an automaton? Well, take a robot for instance. Man calls it an automaton in spite of the fact that he had to slave to put it together before it did its work.

My idea is this: the iron ore would come out itself, smelt itself, form itself in the various shapes and parts needed to construct a robot, then take its correct place and rivet itself. Then the radio brain, electrical eyes and magnet hands take their place; and when it has constructed itself it will conduct the experiments—if a chemical robot—without human supervision. Thus, the latter clause would be true! That's my conception of an automatic robot! Otherwise, its just some metal doing the bidding of a master's brain.

Another thing: the novelette "Beyond the Vanishing Point," by Ray Cummings, is preposterous. The flesh might shrink or grow, but the bone would not! If one shrunk as did George Randolph, one's bones would burst through the flesh.

But in spite of all that, I like the stories that way. Science, in the years to come might discover how to shrink or grow both flesh and bones. I guess I'm taking too much of your time, so adios!—Jay Zee, Chicago, Illinois.

Hot Times in the Fire-House

Dear Editor:

The first Thursday in each month I make a bee-line for the newsstand—and Astounding Stories. It may interest you to know that I have every issue on file that you have put out.

There have been some mighty good yarns in those issues, but the one just at hand contains the best story you have ever published—"Terrors Unseen," by Harl Vincent. There's an author for you; but evidently I don't have to tell you so, as you have given us quite a number of his splendid stories. "Vagabonds of Space" was a wow. Like some of the others who have written in, I would like to see a sequel to this. Harl Vincent is my favorite of all your authors.

A close second is Charles W. Diffin. He is good, too. As your authors appeal to me, in order, I mean. I would line them up in this way: Harl Vincent, Charles W. Diffin, R. F. Starzl, Ray Cummings, Capt. S. P. Meek, Jack Williamson and Murray Leinster.
