Peter sat here until he was tired, watching a snake which twisted its way through the dead leaves, the gray squirrels which ran about now in confidence, fancying themselves perfectly secure, and some birds that had nested in a tree not far away. He hoped that the snake would not reach the birds’ nest and steal the eggs, but it was early in the season yet, and snakes were still sluggish in their movements. He knew that the owls were secure, for their eggs had been hatched some time since, and the young ones were probably well grown. Indeed, there was a possibility that the other birds, if they escaped the snake, might fall a prey to the owls that lived in such close proximity, and that would be only too ready to pounce upon and devour them at the first opportunity.

At last Peter rose from the log, and releasing Sirius with a commendatory pat for his good behavior, he walked off through the woods. There was a sudden rustle in boughs and underbrush, frightened bird notes sounded from the branches, shrill squirrel warnings came from the trunks of trees. All the creatures, which had supposed themselves safe, were terrified by these unexpected movements on the part of the two hitherto motionless objects that had been there so long, and quickly gave notice to their companions that danger was abroad in the forest.

But Peter and Sirius left them unmolested, and continued their way to the outskirts of the wood. It was later than Peter had supposed, but he determined to take a still longer walk and to go home by a round-about way which could be shortened at the end by coming up the branch railroad which led directly through their place.

He was walking quickly over this railroad, and was crossing a bridge which was above the river, when his foot caught on one of the ties, and he slipped between them. Something seemed to snap in his leg, and then a blackness came over him. Strange surging noises sounded in his ears, and he knew no more.

CHAPTER XIII.
PETER MEETS WITH A SERIOUS ACCIDENT.

On the same afternoon upon which Mrs. Wentworth Ward was to arrive at Glen Arden, and which Peter spent in the woods, Roger Madison came home on an early train from Boston and invited his sister to go out on the river with him. Although Margaret was fully ten years older than himself, and therefore had been grown up when he was still a small boy, she had always been his dearest companion. They rode and drove and fished together, they played and sang, they read the same books and loved the same pictures, and the pleasure which came to one was deprived of half its value if it were not shared by the other.

On this May day therefore they were both more than content with their lot when, Margaret being comfortably placed in the canoe, Roger stepped in and pushed away from the shore.

“Up or down shall it be, Margaret?” he asked.

“Either. Anything is charming, even if we were to stay exactly where we are.”

“As you are so agreeable to anything, I think we will go up river. There are not apt to be so many people about there as there are in the neighborhood of Waterview and below. The river is wilder, too. What a beautiful winding stream the Charles is!”
