All the boys on "The Arrow" looked up at Ward's shout of warning, and Jack glanced backward as he heard the call.

"Look out! look out, Tim!" he screamed in his excitement, but the course of "The Arrow" instantly was changed.

Just how it all occurred Ward never knew; whether Jack had for a moment lost control of the sled as he looked backward, or the forward runners of "The Swallow" actually struck the bob he never could tell.

There was for a moment a dull grating sound, as if "The Arrow" had grated on bare ground, and all the boys on it were thrown slightly forward by the sudden checking of the speed.

However, it instantly became apparent that Jack had lost control of the bob. The swift-flying sled left the road, started directly down the bank, and before them, only a few rods away, was a low, rambling stone wall which still appeared above the crust of the snow. There was a shout of alarm from the watching boys by the roadside, a feeling of utter despair in Ward's heart as he perceived there was to be a crash of some kind. But before he or any of the boys could voice their alarm, or roll from the sled which was plunging ahead with no apparent slackening in its speed, there was a sudden shock, and the sled struck the wall, and in a moment Ward felt himself shooting through the air over the heads of his companions.

He was only partially aware of the force with which he struck the hard, smooth crust at last and slid far ahead over its surface. He tried desperately to check his speed, but all of his efforts were without avail, till at last he came sharply against the stone wall which bordered the narrow field on its farther side.

Even then he felt dull and stunned, and for a moment could not move. Just where he was or how he came to be there was not at first apparent to him.

In a brief time, however, he was aware of the shouts and cries behind him and then staggered to his feet. His face and hands were bleeding and his clothing was torn in many places. But all that was instantly forgotten as he perceived from the actions of the boys, who had quickly gathered at the place where the accident had occurred, that something was wrong there. Stumbling, staggering forward, he made his way back, though it seemed to him that every bone in his body was aching and every step gave him pain.

At last he reached the crowd, and as he approached, one of the boys noticing his appearance, turned to him and said quickly, "Are you hurt, Ward?"

"No, I think not," though even while he was speaking he was conscious of the wounds on his face and hands. "No, I think not much," he repeated; "but some of the boys here are, I fear," he hastily added.
