_Likes the "Corner"_

Dear Editor:

This month's issue, May, has the best collection of letters
you've ever published. All it lacked was a letter from
Bernard J. Kenton, that master of epistles and super-science
stories. One of your Readers would like to have "The
Readers' Corner" omitted. For heaven's sake, don't take it
out! I recognize it as one of the best features of our mag,
and whenever I open the covers, turn to it directly after
having glimpsed the table of contents and the announcement
of the stories to appear in the forthcoming issue.

Mr. Joseph R. Barnes--whose letter I enjoyed immensely,
incidentally--will be interested in knowing that "The Mascot
Deep" is already in book form and that "The Disintegration
Machine" and "When the World Screamed," all by the same
author, are under the same covers. He also will be
interested in learning that Ray Cummings' fine story, "Sea
Girl," is also between hard covers.

The idea of putting out a quarterly is a dandy. The other
science fiction quarterlies are mere text-books; there are,
occasionally, of course, a few exceptions. The thought of
the sort of fantastic action stories Astounding Stories
publishes, put together in a magazine doubly thick, is a
pleasing one to contemplate. Reading a story the length of
"Brigands of the Moon" and of such literary merit, complete
in one issue, is a thrill to be looked forward to. By all
means put out such a magazine and have stories by Jack
Williamson, R. F. Starzl and Edmond Hamilton, three of your
best writers, in the first issue.

I'm glad to see that Starzl is coming back with the next
issue. More from him, please. And Hamilton and Williamson
should appear more frequently, too.

A question, Mr. Cummings: Shades of Polter and Tugh!--why
must you always have a deformed character in your stories?
Do they appeal to your dramatic sense?

The news that we're going to have a story from Francis Flagg
brings raptures of delight to my homely face. If it's a
dimensional
