"It's my opinion that our friend would better get out to-night," he whispered. "The boys are holding off in the meanwhile, but if they can't get their breakfast there'll probably be trouble."

Drakesford agreed with this, and shortly afterward he proceeded circuitously toward the troopers' horses.

In the meanwhile, Slaney and his subordinate sat down on the grass well apart from each other and about sixty yards from the cook-shed, and, rolling their blankets about them, prepared to spend the night as comfortably as possible. It was not very dark, though there was no moon, and a slight haze, which promised an increased obscurity, was now creeping across the sky. They could see the black shape of the shed, and it was evident that nobody could slip out from it without their observation; and they had their carbines handy. Slaney would have crept up a little nearer, only that he felt it desirable to keep outside the striking range of the giant-powder, in case Winthrop happened to get drowsy and drop it in the stove.

After a while the track-graders, who had sat among the grass smoking and watching the troopers, began to drift away to their sleeping-quarters. The drama was interesting, but they had no part in it, and they would certainly have to rise soon after sunup to a long day's arduous toil. In the meanwhile, their attitude could best be described as reluctantly neutral. There were a few toughs among them who had no doubt sufficient reason for not loving a policeman of any kind, but the rest recognized the inadvisability of any interference with constituted authority. On the other hand, though they did not know the rights or wrongs of the matter, the desperate, cold-blooded courage of the hard-pressed man appealed to them, and they decided that Corporal Slaney need not look for any effective assistance which it might be in their power to render. Most of them were simple men who lived and toiled in the open, and, as is usual with their kind, their sympathies were with the weaker party.

In an hour or two the last of them had vanished, and if a few still watched outside their tents there was, at least, nothing that suggested their presence to Corporal Slaney. He lay resting on one elbow, with his eyes fixed on the shed, while a little chilly breeze set the dry grasses rustling about him. It was now slightly darker than it usually is on the prairie in summer-time, for the haze had gradually spread across most of the sky. The tents had faded almost out of sight, though the black shape of the shack remained, and now and then, when the breeze sank away, the silence grew almost oppressive. Once the corporal started as he heard a sound in the shed, but he sank down again when he recognized the clatter and rattle that succeeded it. Winthrop, who evidently did not mean to neglect any precaution, was, he decided, putting more fuel into the stove. After that the howl of a coyote came faintly up the breeze, which grew stronger, and the low murmur of the grasses began once more.

A pearly light was growing clearer on the eastern rim of the prairie when at length Slaney, damp with the dew, rose to his feet with a shiver and softly called the trooper, who announced that he had heard nothing suspicious during the night. After a brief parley they crept up cautiously a little nearer the shed, but there was, so far as they could make out, no sign of life within. Indeed, the stillness was becoming suspicious. Moving nearer still, they could look into part of the shed through the open door, and, for the light was getting clearer, it became evident that Winthrop was no longer sitting beside the stove. This was encouraging, because it looked as if he had fallen asleep.

Making a short detour, so as to keep to one side of the entrance, they crept up closer, with faces set and hearts beating a good deal faster than usual; but there was no sound except a faint crackle, apparently from the stove. Then Slaney lay down in the grass and crawled up to the doorway, where he rose and suddenly sprang into the shed. The next moment his voice rang out hoarse with anger, for the place was empty. He waited until the trooper joined him, and then pointed to a little door in the back of the larger building.

"That explains the thing!" he exclaimed. "You looked round the shack?"

"I did," the trooper admitted, and added, somewhat tactlessly, "so did you."

Slaney frowned at this reminder, but it was evident that a discussion as to whose fault it was that Winthrop had got away would in no way assist them in his capture, and they proceeded into the larger building, where they had no trouble in finding an explanation of his escape.
