The clerk handed over the key, and the professor gave the boy the check for his valise at Yates’ suggestion.

“Now, get a move on you,” said Yates to the elevator boy. “We’re going right through with you.”

And so the two friends were shot up together to the fifth floor.


CHAPTER II.

The sky parlor, as Yates had termed it, certainly commanded a very extensive view. Immediately underneath was a wilderness of roofs. Farther along were the railway tracks that Yates objected to; and a line of masts and propeller funnels marked the windings of Buffalo Creek, along whose banks arose numerous huge elevators, each marked by some tremendous letter of the alphabet, done in white paint against the somber brown of the big building. Still farther to the west was a more grateful and comforting sight for a hot day. The blue lake, dotted with white sails and an occasional trail of smoke, lay shimmering under the broiling sun. Over the water, through the distant summer haze, there could be seen the dim line of the Canadian shore.

“Sit you down,” cried Yates, putting both hands on the other’s shoulders, and pushing him into a chair near the window. Then, placing his finger on the electric button, he added: “What will you drink?”

“I’ll take a glass of water, if it can be had without trouble,” said Renmark.

Yates’ hand dropped from the electric button hopelessly to his side, and he looked reproachfully at the professor.
