of isolation and silence--could not help but communicate itself to his
companion, and there resulted a mutual antagonism, which grew into a
dislike, then festered into something more, something strange,
reasonless, yet terribly vivid and amazingly potent for evil. Neither
man ever mentioned it--their tongues were clenched between their teeth
and they held themselves in check with harsh hands--but it was
constantly in their minds, nevertheless. No man who has not suffered the
manifold irritations of such an intimate association can appreciate the
gnawing canker of animosity like this. It was dangerous because there
was no relief from it: the two were bound together as by gyves; they
shared each other's every action and every plan; they trod in each
other's tracks, slept in the same bed, ate from the same plate. They
were like prisoners ironed to the same staple.

Each fought the obsession in his own way, but it is hard to fight the
impalpable, hence their sick fancies grew in spite of themselves. Their
minds needed food to prey upon, but found none. Each began to criticize
the other silently, to sneer at his weaknesses, to meditate derisively
upon his peculiarities. After a time they no longer resisted the advance
of these poisonous thoughts, but welcomed it.

On more than one occasion the embers of their wrath were upon the point
of bursting into flame, but each realized that the first ill-considered

to go free, and so managed to restrain himself.

The crisis came one crisp morning when a dog-team whirled around a bend
in the river and a white man hailed them. He was the mail-carrier, on
his way out from Nome, and he brought news of the "inside."

"Where are you boys bound for?" he inquired when greetings were over and
gossip of the trail had passed.

"We're going to the Stony River strike," Grant told him.

"Stony River? Up the Kuskokwim?"

"Yes!"

The mail-man laughed. "Can you beat that? Ain't you heard about Stony
River?"

"No!"

"Why, it's a fake--no such place."

There was a silence; the partners avoided each other's eyes.

"MacDonald, the fellow that started it, is on his way to Dawson. There's
a gang after him, too, and if he's caught it'll go hard with him. He
wrote the letters--to himself--and spread the news just to raise a
grub-stake. He cleaned up big before they got onto him. He peddled his
tips for real money."

"Ye
