"I say, Jack," said Ward soberly, "this is lots of fun, but it's dangerous too. You don't suppose Tim would leave his bob so that we might happen to strike it on our way down, do you? It would be all day with us if he should do such a thing."

"No, I don't believe Tim would do that," replied Jack lightly, although Ward thought he could see that his friend was troubled by the suggestion. "No, I don't believe Tim would do that," repeated Jack. "He's got the disposition to upset us, but I don't believe he'd do it. He thinks too much of his bob to run the risk of a collision."

Nothing more was said by either of the boys, and in a brief time they arrived at the summit of West Hill and prepared once more for the long ride.

The party was arranged just as it had been in the preceding ride, and as soon as Ward saw that all the boys were ready, he began again to push the heavy load and as the sled started, he ran lightly behind it and then leaped upon it in his former position.

CHAPTER XXI

THE ARROW AND THE SWALLOW

Again the swift descent of the long hill was made, and then once more the boys climbed back to the starting point.

Tim Pickard and his friends were passed each time, but no trouble came, the owner of the other bob either not caring to disturb them then, or else, as Jack suggested, he feared the damage which might come to his own sled from a collision.

When at last the boys returned to their rooms, they were all enthusiastic over the sport of the afternoon and were eagerly looking forward to the following day when the experience might be repeated.

Indeed it was not long before the entire school seemed to feel the contagion of the sport, and sleds and improved bobs were to be seen every afternoon upon the long course of West Hill. Even the towns-people came to share in the coasting, and many strange looking sleds soon made their appearance.
