"Nothing that can make any difference now. They are probably holding him to hamper me. The boy's loyal."

"Yes," growled McCloskey, "and he's Irish."

"Well, my old mother is Irish, too, for the matter of that," snapped Judson. "If you don't like the Irish, you'll be finding a chip on my shoulder any day in the week, except to-day, Jim McCloskey!"

Lidgerwood smiled. It brought a small relaxing of strains to hear these two resurrecting the ancient race feud in the midst of the trouble storm. And when the trainmaster returned to his post in the wire office, and Judson had been sent back to Biggs's to renew his search for the hidden ring-leader, it was the memory of the little race tiff that cleared the superintendent's brain for the grapple with the newly defined situation.

Judson's report was grave enough, but it brought a good hope that the crucial moment might be postponed until many of the men would be too far gone in liquor to take any active part. Lidgerwood took the precautions made advisable by Tryon's threat to steal an engine, sending word to Benson to double his guards on the locomotives in the yard, and to Dawson to block the turn-table so that none might be taken from the roundhouse.

Afterward he went out to look over the field in person. Everything was quiet; almost suspiciously so. Gridley was found alone in his office at the shops, smoking a cigar, with his chair tilted to a comfortable angle and his feet on the desk. His guards, he said, were posted in and around the shops, and he hoped they were not asleep. Thus far, there had been little enough to keep them awake.

Lidgerwood, passing out through the door opening upon the electric-lighted yard, surprised a man in the act of turning the knob to enter. It was the merest incident, and he would not have remarked it if the door, closing behind Gridley's visitor, had not bisected a violent outburst of profanity, vocalizing itself in the harsh tones of the master-mechanic, as thus: "You —— —— chuckle-headed fool! Haven't you any better sense than to come—" At this point the closing door cut the sentence of objurgation, and Lidgerwood continued his round of inspection, trying vainly to recall the identity of the chance-met man whose face, half hidden under the drooping brim of a worn campaign-hat, was vaguely familiar. The recollection came at length, with the impact of a blow. The "chuckle-headed fool" of Gridley's malediction was Richard Rufford, the "Killer's" younger brother.

Lidgerwood said nothing of this incident to Dawson, whom he found patrolling the roundhouse. Here, as at the shops and in the yard, everything was quiet and orderly. The crews for the three sections of the midnight freight were all out, guarding their trains and engines, and Dawson had only Bradford and the roundhouse night-men for company.

"Nothing stirring, Fred?" inquired the superintendent.

"Less than nothing; it's almost too quiet," was the sober reply. And then: "I see you haven't sent the Nadia out; wouldn't it be a good scheme to get a couple of buckboards and have the women and Judge Holcombe driven up to our place on the mesa? The trouble, when it comes, will come this way."
