“It’s an awful dirty place, strikes me,” said Joe. “All the buildings look as if somebody had spilled soot over ’em.”

“I guess somebody has,” Tom answered. “I guess they burn soft coal here. The air’s full of it. Wait till we get to the Rockies, though; there’s the air!”

The trip from Chicago to St. Paul was even more interesting than the first stage, because after a while the train followed the bank of the Mississippi River (the scouts had a railroad folder with a map spread out in their seat, to see where they were every minute), and there was something thrilling to both of them about the first sight of the great river, which they had heard about all their lives.

“Say, it’s yellow, all right,” Joe exclaimed. “I’d rather go swimming in our old hole back home, I guess. It ain’t so awful big, either.”

“Not way up here. We’re a thousand miles from the mouth. But you’d better not try to jump it, even here—not till you get well,” Tom laughed.

At St. Paul they changed once more, for the final train, the trans-continental limited which would take them right through to the Park.

“Golly, we won’t see any of Minnesota,” Tom complained. “It’ll be dark while we go through that. And look at all those lakes we pass.” He pointed to the map.

“Well, there has to be night as well as day out here, just like home. I guess we can’t do anything about it,” said Joe. “I’m kind o’ glad to sleep, at that.”

“Poor old Joe, I forget you get tired,” Tom cried, penitently. “Seems to me I never want to go to sleep, with so much to see!”

“Oh, I’m not tired any more,—just sleepy,” Joe said, bravely. But Tom saw he was tired, and called the porter to make up the berths.
