away, it'll be for all day. I want to eat first."

There, at last, it had come! A man down the street shouted. There
followed a pounding at doors, and then the murmur of exclamations,
questions and replies.

"It sounds like some excitement," yawned Oldham, bringing his chair down
with a thump. "They haven't even rung the first bell yet; let's wander
out and stretch our legs."

He sauntered off the wide back porch toward the front of the house. Bob
followed. When near the gate Bob's mind grasped the significance of one
of the trivial details that his eyes had reported to it some moments
before. He uttered an exclamation, and returned hurriedly to the back
porch to verify his impressions. They had been correct. Oldham had
stated definitely that he had arrived before daylight, that he had been

past. The cowboys listened to the news with interest, and a delight
which they did not attempt to conceal. They denied having seen the
fugitive. The sheriff questioned them perfunctorily. He knew the breed.
George Pollock might have breakfasted with them for all that the denials
assured him.

There appeared shortly on the scene of action a United States marshal.
The murder of a government official was serious. Against the criminal
the power of the nation was deployed. Nevertheless, in the long run,
George Pollock got clean away. Nobody saw him from that day--or nobody
would acknowledge to have seen him.

For awhile Bob expected at any moment to be summoned for his testimony.
He was morally certain that O
