As the children went off to bed Mr. Emerson called out "To-morrow all will be grime and dirt again; fairyland has gone."
"Never mind, Grandfather," cried Ethel Brown, "we won't forget that it is there just the same if only we could see it."
"And we'll think a little about the splendiferousness of the sun, too," called Helen from the elevator. "I never thought much about it before."
CHAPTER XVII
THE MISSING HEIRESS
Mr. Emerson's investigations proved that Stanley Clark had left Brownsville several days previously and had gone to Millsboro, farther up the Monongahela.
He had left that as his forwarding address, the hotel clerk said. This information necessitated a new move at once, so the next morning, bright and early, Mr. Emerson led his party to the river where they boarded a little steamer scarcely larger than a motor boat.
They were soon puffing away at a fair rate of speed against the sluggish current. The factories and huge steel plants had disappeared and the banks looked green and country-like as mile after mile slipped by. Suddenly Roger, who was sitting by the steersman's wheel, exclaimed, "Why, look! there's a waterfall in front of us."
