"Oh, no! we mustn't--not till we've asked leave."

"Well, who'll we ask?" demanded Bess.

"The baggage-man, of course," said Nan, jumping up. "I believe he's
hungry, too."

"Who? the baggage-man?" giggled Bess.

"The puppy, of course," returned Nan.

"We'll feed him some of our pie," suggested Bess.

"He ought to have some warm milk," Nan said seriously.

"Oh, indeed!" exclaimed her chum. "Well, Nan Sherwood, I don't think
anybody's thought to milk the cow this morning."

"Oh, be good, Bess," Nan admonished her. The pup began to whimper again.
"Come on; let's find the man."

The girls ventured farther forward. When they opened the door of the car
at that end, Bess screamed outright.

"Why! it's a tunnel, Nan," she ejaculated. "Do you see?"

"What a lot of snow there must be above us," her chum rejoined,
with gravity.
