it was not through any fault of its own.

The fact that Jenks and Linane were not strong for each other, except to
recognize each other's ability as engineers, was due to an incident of
the past. This incident had caused a ripple of mirth in engineering
circles when it happened, and the laugh was on the older man, Linane.

It was when radio was new. Linane, a structural engineer, had paid
little attention to radio. Jenks was the kind of an engineer who dabbled
in all sciences. He knew his radio.

When Jenks first came to work with a technical sheepskin and a few tons
of brass, Linane accorded him only passing notice. Jenks craved the
plaudits of the older man and his palship. Linane treated him as a son,
but did not warm to his social advances.

"I'm as good an engineer as he is," mused Jenks, "and if he is going to
high-hat me, I'll just put a swift one over on him and compel his
notice."

The next day Jenks approached Linane in conference and said:

"I've got a curious bet on, Mr. Linane. I am betting sound can travel a
mile quicker than it travels a quarter of a mile."

"What?" said Linane.

"I'm betting fifty that sound can travel a mile quicker than it can
travel a quarter of a mile."

"Oh no--it can't," insisted Linane.

"Oh yes--it can!" decided Jenks.

"I'll take some of that fool money myself," said Linane.

"How much?" asked Jenks.

"As much as you want."

"All right--five hundred dollars."

"How you going to prove your contention?"

"By stop watches, and your men can hold the watches. We'll bet that a
pistol shot can be heard two miles away quicker than it can be heard a
quarter of a mile away."

"Sound travels about a fifth of a mile a second. The rate varies
slightly according to temperature," explained Linane. "At the freezing
point the rate is 1,090 feet per second and increases a little over one
foot for every degree Fahrenheit."

"Hot or cold," breezed Jenks, "I am betting you five hundred dollars
that sound can travel two miles quicker than a quarter-mile."

"You're on, you damned idiot!" shouted the completely exasperated
Linane.

Jenks let Linane's friends hold the watches and his friend held the
money. Jenks was to fire the shot.

Jenks fired the shot in front of a microphone on a football field. One
of Linane's friends picked the sound up instantaneously on a three-tube
radio set two
