It was because of his speed that an accident happened to Bert which might have been a very serious one. He was traveling with his head held down, to keep the falling snow out of his face, when he suddenly felt himself falling.

Down, down he went, as though he had stepped into some big hole, or off some high cliff. He gave a cry of alarm, and threw out both hands to grasp something to save himself, but there was nothing to grasp. Down, down went poor Bert!

It was a good thing there was so much snow on the ground. The piles and drifts of white flakes were like so many heaps of feathers, and Bert was thankful when at last, after sliding, slipping, falling and tumbling, he came to a stop, half buried in a deep drift. He was somewhat shaken up, and he had dropped his package of lunch, but at first he did not think he was much hurt until he tried to move his left leg.

Then such a pain shot through the boy that he had to cry aloud. He shut his eyes and leaned back against the pile of snow into which he had fallen. The first flash of pain passed, and he began to feel a little better. But a terrible thought came to him.

“What if my leg is broken?” said Bert, half aloud. “I can’t walk, I can’t go for help, and I’ll have to stay here. Daddy or nobody will know where to find me—not even Nan or Mrs. Bimby! Oh, this is terrible!”

But he knew he must be brave, for he had to help not only himself but his sister and the old woman in the cabin. Clenching his teeth to keep back the cry of pain which he felt would come when he moved his leg again, Bert shifted it a little to one side. The spasm of pain came, but not so bad as at first.

“Maybe it’s only broken a little,” thought the boy. “And I can crawl, if I can’t walk.” He had read of hunters and trappers who, with a broken or badly cut leg, had crawled miles over the snow to get help. Bert wanted to be as brave as these heroes.

But when he moved his leg for the third time and found the pain not quite so bad, he began to take heart. He brushed away the snow from both legs and looked at them. They appeared to be all right, but the left one felt a little queer. And it was not until he had managed to pull himself up, by means of a stunted bush showing through the snow, that Bert knew his leg was not broken.

It was strained a little, and it hurt some when he bore his weight on it, but he found that he could at least walk, if he could not run, and he was thankful for this. He looked up toward the place from where he had fallen, and saw that, without knowing it, he had stepped over the edge of a steep hill. The snow had hidden the edge from Bert, and he had plunged right over it.

“Where’s my lunch?” he asked aloud, and then he saw the package, which had fallen to one side of the place where he had plunged into the drift. Bert picked it up, and then, thankful that his accident was no worse, he went on again.
