"I can't explain, either. And I musn't tell you. It's going to drive me crazy to keep still, but I must not tell."

"You can tell me;" his tone was suddenly authoritative again (quite thrilling its young listener).

"No, I can't. I can't tell any one," but her tone was wavering, with a catch in its note.

Ingram became instantly imperious.

"Yes, you can tell me! You must tell me! It will relieve your mind, and perhaps I can help Alva."

"No, you can't help her; she doesn't want to be helped."

"Well, I can help you, anyway. Just telling me will help you."

Lassie choked.

"Tell me at once," said Ingram, sternly; "I insist upon knowing."
