Eager to do his part now that he was here, Arne went right up to a treetop to get some specially fine branches with clusters of cones. When he came nimbly down, he saw, with some dismay, that the other boys had gone on and that only Herr Engstrand was at hand. He was probably in for a good scolding now, but surely Herr Professor wouldn’t send him home when he had toiled so hard to get up here alone.

Arne started to run after the other boys, but the teacher took two or three long strides, laid a hand on his shoulder, and turned him around. “Just a minute, my boy,” he said. “I have something to say to you.”

Arne’s heart seemed to go right down into his boots. “Yes, sir,” he managed to mumble. “Maybe I shouldn’t have come, but I—well, I did my exercises first, and I didn’t think you said—” His voice trailed miserably off.

“I didn’t say you shouldn’t come,” said the teacher in a matter-of-fact tone. “In fact, I hoped you would, though I didn’t feel I could encourage you to do so, in view of the weather and the distance. Of course I know it takes more than a snowstorm to keep a Norwegian boy off a mountain. In fact, people say mountains and snow are all a Norwegian needs for fun. But I didn’t think you knew the way here.”

“I didn’t really, but—” Arne began and then stopped short, uncertain and embarrassed. He certainly could not tell Herr Professor about Bergel’s note. How could he explain?

Herr Engstrand was going on, “But your cousin told me—” He stopped so long that Arne looked up and, to his great surprise, saw that his teacher was smiling a little. “She is a conscientious little girl, as well as a good pupil, and I think she felt she might not have done right. And then, too, I think she began to get worried about you. So she told me about leaving you the note. And I’ll admit we were all a little anxious when you did not arrive.”

“Those grammar exercises,” said Arne, with a gusty sigh. “They took quite a while. But who thought of the saeter horn? That was a life-saver.”

“It was Bergel who thought of that, and Froken Utvig found it for her. Bergel told me something else, Arne. She told me why you had been late those times. I should have been glad if you had told me yourself.”

“You would?” exclaimed Arne in astonishment, and added, with complete honesty, “I never thought of that.”

Herr Engstrand dropped his hand from Arne’s shoulder. “I see,” was all he said, but his voice made Arne think of the way he himself sometimes felt when he tried very hard to do something and did not succeed.
