Mallory said, "Billy said this was a message from New Fresno?"

"Well, he was wrong, as usual." Determinedly. "It come from Earth's

moon. I know Joe Marlowe's fingers when I hear 'em. Damn, we was

classmates for three years. Before I got crazy and gave up chemistry

for key-pushing--"

"Chemistry!" Mallory started. "Did you say chemistry? Did you and

Marlowe study chemistry together?"

"Yeah. Why?"

"Why! Because that's the answer. Marlowe is nobody's fool. He knew

you were the radioman aboard the _Libra_, prepared a special code,

the key to which would lie in your brain as the 'memory of auld lang

syne'--Bud, look at these figures again. You notice the number '16'

appearing over and over? Even in that thick skull of yours, '16'

suggests--?"

"Oxygen," declared Chandler promptly. "The atomic weight of oxygen."

"And eighty-three point seven? Forty-seven, nine?"

"Krypton. And--let's see--titanium?"

"Right! Grab a pencil, pal! I think we've got a solution here. Jot

these down--krypton, europium, thorium, erbium--Hold it!" He looked at

his companion disgustedly. "Just the symbols, you dope! Don't you see?

The symbols of the various elements employ every letter in the English

language except 'j' and 'q'--and those are the two least commonly used,

anyway. Start over. Krypton--"

"Kr," said Bud.

"Europium--"

"Eu."

"Thorium. Erbium--"

"'Kreuther'!" howled Bud. "That's it, Dan! Keep going!"

The message slowly scrawled its way onto paper. A word appeared,

another, another. Then:

"Ten point twenty-five!" said Mallory. "Followed by 69.87! What the

hell are they?"
