“It’s a good thing people aren’t all alike,” he said. “If they were, either the wilds or the civilized places would be filled to capacity.”

Although the youths were anxious to reach their destination, they found the drive East interesting, even though they had made it before. Their attention was so held by the many interesting sights that, almost before knowing it, they found themselves in Pittsburgh, after having eaten a lunch several hours before. In the business district they engaged rooms in a small but comfortable hotel.

If Mr. Wilson and the naturalist were tired, the youths were not. They insisted on taking a look at Pittsburgh, which they had not seen for many months. An hour or two of looking around and they would return to the hotel, remarked Bob.

During that time the young men found much to hold their interest. The great fiery blast furnaces, the towering skyscrapers, the crowds of pleasure seekers, and the lights of river boats all kept them gay with amusement.

At last, when they finally made themselves return to the hotel, they found that their friends had gone. Evidently the lure of a great city was too much for them.

“And Mr. Wilson said he was dead tired,” said Joe with a smile.

“They’re no different from us,” said Bob. “Want to keep on the go, I guess.”

Mr. Wallace and his friend did not return until late, much to the amusement of the youths. Both men wore a sheepish look as they caught sight of Bob and Joe.

“Sorry, but we just had to get out,” grinned the newspaper man, walking drowsily through the lobby. “Couldn’t stand it to stay inside.”
