She nodded, her eyes shining with mischief.

"But," the colonel continued, "Bob is a bluff. He's had all the climbing he can stand. Nothing but a chest full of treasure or a maiden in distress would take him a step farther."

"After lunch," said Mr. Jonstone, "I shall."

"Do it now! Lunch won't be ready for an hour. Any kind of a walker could make the top of the mountain and be back in that time. But I'll bet you anything you like that you can't."

"You will? I'll bet you fifty dollars."

"Done!"

Mr. Jonstone leaped to his feet in a business-like way, waved his hand to them, and started briskly off and up along the trail by which they had come, and which ended only at the very top of the mountain. It wasn't that he wanted any more exercise. He wanted to get away for a while to think things over. He had learned on that day's excursion, or thought he had, that two is company and that three isn't. The pleasant interchangeableness of the trio's relations seemed suddenly to have undergone a subtle change. It was as if Maud and Colonel Meredith had suddenly found that they liked each other a little better than they liked him.

So it wasn't a man in search of exercise or eager to win a bet who was hastening toward the top of a mountain, but a child who had just discovered that dolls are stuffed with sawdust. He suffered a little from jealousy, and a little from anger. He could not have specified what they had done to him that morning, and it may have been his imagination alone that was to blame, but they had made him feel, or he had made himself feel, like a guest who is present, not because he is wanted but because for some reason or other he had to be asked.

He walked himself completely out of breath and that did his mind good. Resting before making a final spurt to the mountain-top, he heard men's voices shouting and hallooing in the forest. The sounds carried him back to certain coon and rabbit hunts in his native state, and he wondered what these men could be hunting. And having recovered his breath, he went on.
