"What's the trail, Daddy?" asked Teddy of his father.

"Oh, it means the marks the Indians' ponies may have left in the soft ground," said Mr. Martin. "Uncle Frank and his cowboys will try to trail, or follow, the marks of the horses' feet, and see where the Indians have gone."

"Can't I come?" asked Teddy. "I can ride good now!"

"Oh, no indeed you can't go!" cried Mother Martin. "Are you going?" she asked her husband.

"Yes," he answered. "I think I'll go on the trail with Uncle Frank."

CHAPTER XVII

THE CURLYTOPS ALONE

Teddy and Janet sat on a bench outside the cowboys' bunkhouse, as their father, Uncle Frank and a number of the ranchmen rode away over the prairies on the trail of the Indians. The Curlytops did not seem very happy.

"Don't you wish we could go, Jan?" asked Teddy, after he and his sister had sat in silence for some time.
