Dave swung round on his loyal assistant.

"Use every log in the reserve. Every one, mind. We've got to gamble. If Mason keeps us short we're done anyway. Maybe the fever will let up, and things'll work out all right."

Dave flung his book aside and stood up. His heavy face was more deeply lined than it had been at the beginning of summer. He looked to be nearer fifty than thirty. The tremendous work and anxiety were telling.

"Get out to the shoots," he went on, in a sharp tone of command he rarely used. "I'll see to the tally. Keep 'em right at it. Squeeze the saws, and get the last foot out of 'em. Use the reserve till it's done. We're up against it."

Dawson understood. He gave his chief one keen glance, nodded and departed. He knew, no one better, the tremendous burden on the man's gigantic shoulders.

Dave watched him go. Then he turned back to the desk. He was not the man to weaken at the vagaries of ill fortune. Such difficulties as at the moment confronted him only stiffened his determination. He would not take a beating. He was ready to battle to the death. He quietly, yet earnestly, cursed the fever to himself, and opened and reread Mason's letter. One paragraph held his attention, and he read it twice over.

"If I'm short on the cut you must not mind too much. I can easily make it up when things straighten out. These hands I'm taking on are mostly 'green.' I can only thank my stars I'm able to find them up here. I can't think where they come from. However, they can work, which is the great thing, and though they need considerable discipline—they're a rebellious lot—I mean to make them work."

It was a great thought to the master of the mills that he had such men as Bob Mason in his service. He glowed with satisfaction at the thought, and it largely compensated him for the difficulties besetting him. He put the letter away, and looked over the desk for a memorandum pad. Failing to find what he required, he crossed over to a large cupboard at the far corner of the room. It was roomy, roughly built, to store books and stationery in. The top shelf alone was in use, except that Dawson's winter overcoat hung in the lower part. It was on the top shelf that Dave expected to find the pad he wanted.

As he reached the cupboard a terrific crash of thunder shook the building. It was right overhead, and pealed out with nerve-racking force and abruptness. It was the first attack of the threatened storm. The peal died out and all became still again, except for the shriek of the saws beyond the partition walls. He waited listening, and then a strange sound reached him. So used was he to the din of the milling floor that any unusual sound or note never failed to draw and hold his attention. A change of tone in the song of the saws might mean so much. Now this curious sound puzzled him. It was faint, so faint that only his practiced ears could have detected it, yet, to him, it was ominously plain. Suddenly it ceased, but it left him dissatisfied.

He was about to resume his search when again he started; and the look he turned upon the door had unmistakable anxiety in it. There it was again, faint, but so painfully distinct. He drew back, half inclined to quit his search, but still he waited, wondering. The noise was as though a farrier's rasp was being lightly passed over a piece of well-oiled steel. At last he made up his mind. He must ascertain its meaning, and he moved to leave the cupboard. Suddenly a terrific grinding noise shrieked harshly above the din of the saws. It culminated in a monstrous thud. Instinctively he sprang back, and was standing half-inside the cupboard when a deafening crash shook the mills to their foundations. There was a fearful rending and smashing of timber. Something struck the walls of the office. It crashed through, and a smashing blow struck the cupboard door and hurled him against the inner wall. He thrust out his arms for protection. The door was fast. He was a prisoner.
