Things were certainly focusing around Fordham spur, there was no doubt of it. That point of the road was a decided point of interest to Ralph every time the Overland Express neared the spur on succeeding trips. He could only conjecture that Zeph and the Canaries and others in whom Zeph was interested, were located somewhere in the vicinity. However, he caught no sight of any person in the neighborhood of the spur as he passed it. The thing was getting to be a worry to the young engineer, but although he daily promised himself he would manage some way to visit the place, no favorable opportunity presented.

The run to Rockton and back had become harder as cold weather came on. There was a call for extra vigilance and close attention to routine. A snowstorm caught them one night on the out run, and Ralph found out that it was no trifle running with blurred signals among the deep mountain cuts. A great rain followed, then a freeze up, then another heavy fall of snow, and the crew of the Overland Express had a rigorous week of it.

They had made the run to Rockton four hours late on account of a broken bridge, and the next evening when they reported at the roundhouse, engineer and fireman found a cancelled trip instead of readiness for their regular return run 223 to Stanley Junction. The foreman was busy in his office at the telephone, receiving continual instructions from the dispatcher. He was sending men and messengers in every direction. The exigencies of the hour required blockade and wrecking crews. The foreman looked bothered and worried, and nodded to Ralph and Fogg in a serious way as there was a lull at the ’phone.

“No run to-night, boys,” he announced. “You’d better get back to your warm beds.”

“Blockade on the Mountain Division?” inquired the fireman.

“Worse than that. The whole division is annulled this Side of Fordham, and that’s over half the run. Two bridges down, a freight wreck at Wayne, and the mountain cuts are choked with drifts. I doubt if you will break through for a couple of nights.”

“H’m,” observed Fogg. “I fancied to-day’s storm would shut up things.”

“It has. We’re half clear south, but west and north there isn’t a wheel moving within fifty miles.”

“We may as well make the best of it then, Fairbanks,” said the fireman, “and get back to our boarding house.”

The speaker started for the door and Ralph followed him. Just then with a sudden roar of 224 the tempest outside the door was swept open. Two snow-covered forms came in.
