The clouds knit again overhead, but as yet the air was clear of snow. The temperature, however, seemed steadily falling. The breath of the horses was a steam cloud; the potholes in the marsh were gray and lifeless with ice. And it seemed to Virginia that the wild things that they passed were curiously restless and uneasy; the jays flew from tree to tree with raucous cries, the waterfowl circled endlessly over the gray lakes.

This impression grew more vivid as the hours passed; and there was an elusive but sinister significance about it that engrossed her, but which she couldn't name or understand. She didn't mention the matter to Bill. She couldn't have told why, for the plain reason that in her simplicity she was not aware of her own virtues. A sportswoman to the last hair, she simply did not wish to depress him with her fears. There was a suspense, a strange hush and breathlessness in the air that depressed her.

The same restlessness that she observed in the wild creatures began to be noticeable in the horses. Time after time they bolted from the trail, and the efforts of all the party were needed to round them up again. Their morale—a high degree of which is as essential in a pack train as in an army—was breaking before her eyes. They seemed to have no spirit to leap the logs and battle the quagmire. They would try to encircle the hills rather than attempt to climb them.

She wondered if the animals had a sixth sense. She was a wide-awake, observing girl, and throughout the trip she had noticed instances of a forewarning instinct that she herself did not possess. On each occasion where the horses were more or less unmanageable she found, on progressing farther, some dangerous obstacle to their progress,—a steep hill or a treacherous marsh. Could it be that they were forewarned now?

Fatigue came quickly this afternoon, and by four o'clock she was longing for food and rest. She was cold, the snow had wet the sleeves and throat of her undergarments, the control of her horse had cost her much nervous strength. The next hour dragged interminably.

But they were descending now, a steep grade to the river. Twilight, like some gray-draped ghost of a shepherdess whom Apollo had wronged and who still shadowed his steps, gathered swiftly about them.

Bill urged his horse to a faster walk; tired as the animal was he responded nobly. Because Virginia's horse was likewise courageous he kept pace, and the distance widened between the two of them and the remainder of the pack train. Lounsbury's shrill complaints and Vosper's shouts could not urge their tired mounts to a faster gait. The shadows deepened in the tree aisles; the trail dimmed; the tree trunks faded in the growing gloom.

"We won't be able to see our way at all in five minutes more," Virginia told herself.

Yet five minutes passed, and then, and still the twilight lingered. The simple explanation was that her eyes gradually adjusted themselves to the soft light. And all at once the thickets divided and revealed the river.

She didn't know why her breath suddenly caught in awe. Some way the scene before her eyes scarcely seemed real. The thickets hid the stream to the right and left, and all she could see was the stretch of gray water immediately in front. It was wide and fretful, and in the half-light someway vague and ominous. It had reached up about the trunks of some of the young spruces on the river bank, and the little trees trembled and bent, stirred by the waters; and they seemed like drowning things dumbly signaling for help. Because the farther bank was almost lost in the dusk the breadth of the stream appeared interminable. In reality it was a full ninety yards at the shallower head of the rapids where the moose trail led down to the water.
