When the top of the hill was reached, the foreman gathered up the reins, called upon the horse to quicken his pace, and away they went down the slope at a tearing gallop.

Deep Gully well deserved the name that had been given it when the road was made. A turbulent torrent among the hills had in the course of time eaten a way for itself, which, although very narrow, made up for its lack of breadth by a great degree of depth. It was a rather picturesque place in summer time, when abundant foliage softened its steep sides; but in winter, when it seemed more like a crevasse in a glacier than anything else, there was no charm about it. The bridge that crossed it was a very simple affair, consisting merely of two long stringers laid six feet apart, and covered with flattened timbers.

Upon this slight structure the jumper descended with a bump that woke Frank from his pleasant nap, and, putting aside the buffalo-robe, he sat up in the sleigh to gather his wits. It was well he did, for if ever he needed them it was at that moment. Almost simultaneous with the thud of the horse's feet upon the bridge there came a crash, a sound of rending timbers, the bridge quivered like a ship struck by a mighty billow, and the next instant dropped into the chasm below, bearing with it a man, and boy, and horse, and sleigh!

Full thirty feet they fell; the bridge, which had given way at one end only, hurling them from it so that they landed at the bottom of Deep Gully in a confused heap, yet happily free from entanglement with its timbers. So soon as he felt himself falling Frank threw aside the robes and made ready to spring; but Johnston instinctively held on to the reins, with the result that, being suddenly dragged forward by the frantic plunging of the terrified animal, he received a kick in the forehead that rendered him insensible, and would have dashed his brains out but for the thick fur cap he wore, while the jumper, turning over upon him, wrenched his leg so as to render him completely helpless.

Frank was more fortunate. His timely spring, aided by the impetus of their descent, carried him clear of the horse and sleigh, and sent him headlong into a deep drift that filled a hollow at the gully's bottom. The snow-bank opened its arms to receive him, and buried him to the hips. The first shock completely deprived him of breath, and almost of his senses too. But beyond that he received no injury, and was soon struggling with all his might to free himself from the snow that held him captive. This proved to be no easy task. He was pretty firmly embedded, and at first it seemed as though his efforts at release only made his position worse.

"This is a fine fix to be in!" said he to himself. "Buried in a snow-drift; and dear knows what's happened to Mr. Johnston."

He had been hoping that the foreman would come to his assistance, but getting no reply to his shouts, he began to fear lest his companion might be unable to render any help. Perhaps, indeed, he might be dead! The thought roused him to still greater exertions, and at last by a heroic effort he succeeded in turning a kind of somersault in his cold prison, which had the happy result of putting his head where his heels had been. To scramble out altogether was then an easy job, and in another instant he was beside the sleigh.

His first thought was that his worst fears were realized. Certainly the sight was one that might have filled a stouter heart with chill alarm. The horse had fallen into a deep drift, which covered him to the shoulders, and rendered him utterly helpless, entangled as he was with the harness and the over-turned jumper. He had evidently, like Frank, been struggling violently to free himself, but finding it useless, had for a time ceased his efforts, and stood wild-eyed and panting, the picture of animal terror. On seeing Frank he made another frantic plunge or two, looking at the boy with an expression of agonized appeal, as though he would say,—

"Oh, help me out of this dreadful place!"

And glad would Frank have been to respond to the best of his ability. But the poor horse could not be considered first. Half under the sleigh, half buried in the snow, lay the big foreman, to all appearance dead, the blood flowing freely from an ugly gash in his forehead, where the fur cap had failed to protect him entirely from the horse's hoof.
