“I don't know his name. Never saw him before. He rode out here on horseback.”

The envelope, though a good one as to quality, was dirty on the outside. Tom Reade hastily broke the seal and read:

“If you don't get away from Paloma pretty soon your presence will hold the railroad up for a longtime to come! Get out, if you're wise, or the railroad will suffer with you!”

“I reckon the fellow who wrote that was sincere enough,” said Tom, as he passed the letter over to his chum. “However, I don't like to feel that I can be seared by any man who's too cowardly to sign his name to a letter.”

CHAPTER VI. THE GENERAL MANAGER “LOOKS IN”

Neither Tom nor Harry was stupid enough to be wholly unafraid over the threats of the day. Both realized that Jim Duff and the latter's associates were ugly and treacherous men who would fight sooner than be deprived of their chance to fleece the railway workmen. Yet neither young engineer had any intention of being scared into flight.

“They'll put up a lot of trouble for us,” said Tom that afternoon, as the two chums talked the matter over. “They may even go to extremities, and—”

“Shoot us?” smiled Hazelton, though there was a serious look under his smile.

“Yes; they may even try that,” I nodded Tom. “Though they won't make an open attempt. They may try to get us from ambush at night. They will be desperate, though not over brave. Recollect, Harry, that the better element in Paloma won't stand much nonsense. There are no braver men in the world than are found right in Arizona, and no men more decent.”
