On the following morning the rain was still falling, but by ten o’clock the sky brightened a little, and the Percivals, with the exception of Bess, set out for a walk down the track. There was a long snow shed not far away, from which Tom hoped to get a good operating field for his kodak.

Hardly had they clambered to the top of the structure and “pressed the button” once, when a flying gust of rain, backed by a portentous black cloud, sent them flying down again.

“Let’s come in under the shed,” proposed Tom. This, however, was so cold and damp, that Fred and Randolph, seeing some detached freight cars, a few rods up the track, started off to explore for a better shelter.

A minute or two later they were beckoning and shouting to the rest of the party.

“Run for it!” they called out. “Plenty of room here for all hands!”

Pet distanced the other girls, and was mounting a short flight of steps to the end of the nearest freight car, when what was her surprise to be met at the door by a fresh-faced, modest-looking young woman.

“Come in,” she said simply. “I hope you haven’t got wet,” and led the way to the interior of the car.

“It’s like a fairy story,” whispered Pet to Kittie, as the latter scrambled up the steps. “Is she a princess in disguise?”

“Only so far as she is a true ‘King’s Daughter’ in her hospitality,” said Mr. Percival, catching Pet’s question, and replying in the same tone.

In trooped the excursionists, a dozen or more of them, all looking about them in amazement.
