“Not with a bob like this. Look out there!” Frank yelled as he narrowly missed running into a solitary coaster.

The path to which the girl referred was a sort of lane, running off the main hill road, dipping down, and then suddenly shooting up again, crossing over a slight rise, and finally going down to a small pond. It was a semi-public road, but seldom used. To attempt to negotiate it with a swift bob was perilous, for the least mistake in steering, or a slight accident would send the sled off to one side or the other of the small hill, making an upset almost certain, and, likely broken bones, if nothing worse.

“There goes one boy, now,” went on the girl back of Frank, as a coaster shot into the hollow.

“Yes, but he only has a small sled. I’ll not try it. If you girls want to——”

“Oh, no indeed!” she hastened to assure him. “This is too much fun. It’s good of you to ask us.”

The coast soon came to an end, and then came the hard work of dragging the sled up the hill again.

“I wish they had double acting hills,” remarked Tom as he pulled on the rope. “Slide down ’em one way, and, when you get to the bottom they’d tip up, and you could slide back—sort of perpetual motion.”

“You don’t want much,” commented Sid with a laugh.

As the boys reached the top of the slope there dashed up a sled filled with young people, drawn by two prancing horses. And fastened to the rear of the sled, was a large bob.
