he
case. And this--these two viewpoints blended in his
brain--gives him his perception of "depth," of
"solidity"--the difference between a real scene of three
dimensions and a painted scene on a canvas of two dimensions
with only the artist's skill in perspective to simulate the
third.

And I cannot refrain from mentioning that in Government
tests of the Anti-War Department to determine the perfection
of the invisibility of the X-flyers, it was a one-eyed man
who proved that they were not always totally invisible!--Ray
Cummings.

_Thank You_

Dear Editor:

I just want you to know this: I am a reader of your truly
named Astounding Stories. I really enjoyed reading the
"Spawn of the Stars," also "Brigands of the Moon," and I am
very glad to hear that we are going to have another of
Charles W. Diffin's stories in the next issue--"The Moon
Master."--J. R. Penner, 376 Woodlawn Ave, Buffalo N. Y.

_"A Wiz"_

Dear Editor:

I am only a young girl sixteen years of age but am greatly
interested in science. I have no master mind by any means,
but have worked out many a difficult problem in school for
my science prof.

Your magazine is a wiz. I haven't missed an instalment
since it started. Give us more stories like "Monsters of
Moyen," and "The Beetle Horde."--Josephine Frankhouser, 4949
Chestnut St., Philadelphia, Pennsylvania.

_"Pretty Good"_

Dear Editor:

I received Astounding Stories for May and it is pretty good.
The next issue is number six, and I hope it is better than
the previous ones. There have been some stories that do not
belong in a Science Fiction magazine, such as: "The Cave of
Horror," "The Corpse on the Grating," "The Soul Master," and
"The Man who was Dead." There is also another story that was
printed in the May issue that, so far as I think, does not
belong in this magazine: that is, "Murder Madness."

Even all the other stories seem to be fantastic. Weird. Why
not try to publish something on the H. G. Wells, E. R.
Burroughs type of stories, also Ray Cummings' "The Man who
Mastered Time," or "The Time Machine," by Wells?--Louis
Wentzler, 1933 Woodbine St., Brooklyn, N. Y.
