I AM HERE. Helen.

Well, you had quite a discourse from the professor, and a wonderful one it is! I am glad that he wrote to you on the subject, as it clears many doubts that you or your friends may have. He has not finished yet, but he saw you were tired and stopped.

(I think he finds me to be a good channel to express his thoughts.)

Yes, that is what he said, and I am so glad that you realize that he uses your brain as well as your hand. Why, Ned, without your brain, we could not write at all. So, don’t think that we merely use your hands, for your brain is the more important of the two.

Your own true and loving,

HELEN.
