ver the chasm. The next instant he
was grappling with Buck on the extreme edge, while Hans and Pete were
dragging them back into safety.

"It's uncanny," Pete said, after it was over and they had caught their
speech.

Thornton shook his head. "No, it is splendid, and it is terrible, too.
Do you know, it sometimes makes me afraid."

"I'm not hankering to be the man that lays hands on you while he's
around," Pete announced conclusively, nodding his head toward Buck.

"Py Jingo!" was Hans's contribution. "Not mineself either."

It was at Circle City, ere the year was out, that Pete's apprehensions
were realized. "Black" Burton, a man evil-tempered and malicious, had
been picking a quarrel with a tenderfoot at the bar, when Thornton
stepped good-naturedly between. Buck, as was his custom, was lying in a
corner, head on paws, watching his master's every action. Burton struck
out, without warning, straight from the shoulder. Thornton was sent
spinning, and saved himself from falling only by clutching the rail of
the bar.

Those who were looking on heard what was neither bark nor yelp, but a
something which is best described as a roar, and they saw Buck's body
rise up in the air as he left the floor for Burton's throat. The man
saved his life by instinctively throwing out his arm, but was hurled
backward to the floor with Buck on top of him. Buck loosed his teeth
from the flesh of the arm and drove in again for the throat. This time
the man succeeded only in partly blocking, and his throat was torn open.
Then the crowd was upon Buck, and he was driven off; but while a surgeon
checked the bleeding, he prowled up and down, growling furiously,
attempting to rush in, and being forced back by an array of hostile
clubs. A "miners' meeting," called on the spot, decided that the dog had
sufficient provocation, and Buck was discharged. But his reputation was
made, and from that day his name spread through every camp in Alaska.

Later on, in the fall of the year, he saved John Thornton's life in
quite another fashion. The three partners were lining a long and narrow
poling-boat down a bad stretch of rapids on the Forty-Mile Creek. Hans
and Pete moved along the bank, snubbing with a thin Manila rope from
tree to tree, while Thornton remained in the boat, helping its descent
by means of a pole, and shouting directions to the shore. Buck, on the
bank, worried and anxious, kept abreast of the boat, his eyes never off
his master.
