"Why, boys, that's beautiful! Let's try that verse once more, and you two whistle the accompaniment a little stronger in the chorus; or how would it do if you just came in on the chorus? I believe that would be more effective. Let's try the first verse that way; you boys sing during the verse and then whistle the chorus just as you did now. We really need your voices in the verse part, they are so strong and splendid. Let's try it now." And she started off again, the two big astonished fellows meekly doing as they were told, and really the effect was beautiful. What was their surprise when the whole song was finished to have her say, "Now everybody whistle the chorus softly," and then pucker up her own soft lips to join in. That completely finished the whistling stunt. Jed realized that it would never work again, not while she was here, for she had turned the joke into beauty and made them all enjoy it.

And she began to sing again, while they all joined anxiously in, really trying to do their best. The instant the last verse died away, Margaret's voice took their attention. "Two years ago in Boston two young men, who belonged to a little group of Christian workers who were going around from place to place holding meetings, sat talking together in their room in the hotel one evening." There was instant quiet, a kind of a breathless quiet. This was not like the beginning of any lesson any other teacher had ever given them. Every eye was fixed on her. "They had been talking over the work of the day, and finally one of them suggested that they choose a Bible verse for the whole year--" There was a movement of impatience from one back seat, as if Jed had scented an incipient sermon, but the teacher's voice went steadily on:
