grows up to full manhood or womanhood and remains in that state of the
body's highest excellence. While the child is developing the rays
stimulate his progress; anything beyond that would be decaying, a
condition the rays prevent."

Accustomed though I had become to a long recital of the most marvelous
accounts without interrupting, I could not suppress an exclamation of
astonishment at the information that Martians enjoy everlasting life.

Almos received my evident amazement with the quiet smile I had grown
accustomed to observe upon such occasions, and, with a view of
illustrating the point further, said:

"Although one's actual age becomes a very unimportant matter when,
instead of being limited to sixty or seventy years, it extends over
hundreds of years, I can readily ascertain my age, from the fact that I
was twenty years old at the time these wonderful rays were discovered. I
have lived, then, about six hundred of Earth's years, or three hundred
Martian years."

"Six hundred years!" I exclaimed, as I looked at the reflection of his
handsome face; his eyes flashing, his cheeks aglow with ruddy health,
his whole countenance animated with the full vigor of manhood.

"Of course, we do not know how long the effects of regenerating rays
will make it possible to live," pursued Almos, "but in theory, it would
seem that by their daily use perfect health will be assured, and life
itself will continue indefinitely."

"And death become unknown on Mars!" I added, enthusiastically.
