"Pretty nice!" Mr. Nelson agreed.

"I'm beginning to wish we were at Gold Run now," confided Mollie, after dining. She and Amy had slipped into the seat opposite Betty and Grace.

"Oh, I think it's all fun," cried Betty, for she was always the last of the Outdoor Girls to feel tired. "We change at Chicago to-morrow afternoon," she added. "And then two more nights on the train, and then Gold Run!"

"Oh, that sounds good," cried Mollie, adding eagerly: "Tell me, Betty, shall we be able to choose any horse we want for our own particular mount?"

"Oh, yes," said Betty, adding with a smile: "It will be interesting to see the kind of horse each one of you will choose. Amy will like the gentle one, Grace will choose hers for its looks and yours will be the most vicious one in the pack, Mollie."

"Well, I like that!" said Mollie unperturbed. "She wants to kill me off even before I get there."

"Pack?" murmured Amy. "Is a 'pack' of horses right?" But no one answered her.

"I wonder," mused Grace dreamily, "if there will be a tan one—all tan, you know, without even a spot of any other color——"

"Oh, of course," laughed Betty. "If we haven't an all tan one in the corrals at Gold Run, we'll send to the nearest ranch and have one imported for you. Don't worry your little head about that."

A little while after that they stopped at a water station, and most of the passengers got off to stretch their cramped limbs. And, as the conductor informed them that they would be there for fifteen minutes at least, the girls followed the general example.
