ne
before. Wesso's illustration leaves nothing to be desired.

Going straight through the book: "The Monsters of Mars."
Good old Edmond Hamilton saves the world for us again in the
very nick of time--and we like it, too! Here's hoping
there's a million more dangers threatening Terra for Mr.
Hamilton to save us from! By the way, I wonder who drew the
illustration for this story? I can't make out his name.
Next: "The Exile of Time," by Cummings. Exciting and well
illustrated. "Hell's Dimension" is well-written and very
interesting. Would have liked it longer. "The World Behind
the Moon" is splendid. More by Mr. Ernst, please. More from
Mr. Gilmore, too, because of his novelette, "Four Miles
Within." "The Lake of Light" by that popular author Jack
Williamson surpasses his "The Meteor Girl" in a recent issue
of "our" magazine. And now I come to the last and perhaps
most interesting story of the issue: Mr. Sewell Peaslee
Wright's record of the interplanetary adventures of the
Special Patrol as told by Commander John Hanson. This series
is unsurpassable in its vivid realness. I can't help but
believe that these tales really occurred, or will occur in
the distant future. And Mr. Wright is as expert at
conceiving new forms of life as Edmond Hamilton is at saving
our Earth.

"The Readers' Corner" is an interesting feature, and I am
glad to hear that "Murder Madness" and "Brigands of the
Moon" are now in book form.--Forrest J. Ackerman, 530

Dear Editor:

After reading Mr. Greenfield's letter in your April issue
regarding my story, "An Extra Man," I feel that I should
like to call his attention to a point which, it seems to me,
he has overlooked, namely, that the reconstructed men were
not composed of the original physical matter of the
disintegrated man but of identical elements, all of which
are at present known and available to science.

According to the hypothesis, Drayle could have produced as
many entities as he desired and provided for, just as a
radio broadcast is reproduced in as many places as are
prepared for its reception. The vibrations alone are
transmitted, and the reproduction is the result of a
reciprocal mechanical action by physical matter at
