"Cricky! What will draw it? Where is the span of noble steeds to be found? Old Bobsky would break his neck."

"One horse. One wonderful horse, Bob!" cried Betty clapping her hands suddenly. "I am sure I'm right. Uncle Dick!"

"What do you mean, Betty?" cried Bobby, shaking her. "What horse?"

"Gravitation," announced Betty, her eyes shining. "That's his name."

"Great goodness!" gasped Bob. "I see a light. But Betty, how'd we steer it?"

"The front runners are attached to the tongue. Tie ropes to the tongue and steer it that way," Betty said, so eagerly that her words tumbled over each other. "Can't we do it, Uncle Dick? We'll all pile into the pung, with a lot of straw to keep us warm, and just slide down the hills to the railroad station. What say?"

For a while there was a good deal said by all present. Mr. and Mrs. Canary at first scouted the reasonableness of the idea. But Mr. Gordon, being an engineer and, as Bob said, "up to all such problems," considered Betty's suggestion carefully.

In the first place the need was serious. Especially for the much troubled Ida. If she could not reach the dock on New York's water-front by eleven o'clock the next morning, her aunt would doubtless sail on the San Salvador, and then there was no knowing when the English girl would be able to find her only living relative.

The party had ridden over the mountain road in coming to Mountain Camp, and Uncle Dick remembered the course pretty well. Although it was a continual grade, as one might say, it was an easy grade. And there were few turns in the road.

Drifted with snow as it was, and that snow crusted, the idea of coasting all the way to the railroad station did not seem so wild a thought. The road was fenced for most of the way on both sides. And over those fences the drifts rose smoothly, making almost a trough of the road.
