"Don't let me detain you," said Van Tassel courteously. The electric jewels were again running in lines of light around the buildings. Jack could see the expression in Mildred's face as she stood before him.

She waited a moment and Ogden stepped aside to find the guide.

"I don't want to see a rocket go sputtering over this place," explained Jack, for the girl's eyes demanded something.

She gave a short laugh. "You poor, provincial Bostonian," she remarked. "Go your way; and when you discover what the fireworks of the White City really are, perhaps your fastidiousness will not be shocked. Certainly, Mr. Ogden, I am ready. Au revoir, Jack."

"Good-by, old fellow," said Ogden, as Mildred resumed her position in the chair. He was beaming again with relief from the apprehended loss of Miss Bryant's society.

Van Tassel moved away in the opposite direction from that they took: but no amount of attempted concentration on his surroundings would restore to him the dreamy delight of half an hour ago. He saw continually the reproach and surprise in Mildred's eyes.

"What right had I to take her away from Ogden?" his thoughts protested. "It was all nonsense for her to think that hospitality demanded it."

Then his reflections passed over from the indignant hazel eyes to Miss Bryant's cavalier. The latter's uneasy devotion had been apparent even in the few phrases Jack had heard him say. The eagerly bent head, the short nervous laughs with which he interspersed his sentences told the story: and instantly curiosity leaped up in Van Tassel's heart as to Mildred's real sentiments toward her admirer.

She had said she especially wanted Jack not to leave her to-night. What did that mean? Jack walked a little faster because he suddenly knew that it was the fact that she had said that, coupled with Ogden's lover-like manner which had made him hold aloof.

He had made a point of giving Ogden his chance, and now he felt ashamed of it. Why should he have felt injured because Mildred had a lover? Probably she had a dozen, and what wonder if she had?
