What they do not know is, that Mr. D—— and the doctor have already fitted up two rooms in the most secluded part of the closed-up wing, and that the "insane" man will be removed to those rooms to-night.

One fact concerning le Docteur, your expert has failed to discover, is that at some time the man has made a study of medicine. This is only a theory of mine, not a discovery; but when I tell you what he did, I think that you both will agree with me. A few days ago the doctor walked down to the village one morning, and coolly presented himself at the door of Doctor G——'s office.

Doctor G—— is the least popular and least skillful of the three physicians here, but of course the city man was not supposed to know that. He, the city doctor, informed Doctor G—— that although his employer had not desired it, as he had perfect confidence in the present treatment of Mr. A——, still it was always his practice to consult with another physician.

Doctor G—— came, to find the patient in a bedrugged stupor. He endorsed everything le Docteur chose to say, and went away feeling much puffed-up because of having been called in to consult with a New York physician.

There is but one thing more that I must accomplish, and that must be done to-night, if possible. If I succeed in this, two days more will see me en route for the city. If I fail—then I must remain here, if I can, and try again. In any case, I must make my new move within the week. So look out for the chrysalis; it remains for you to develop it into the butterfly.

This letter chanced to arrive during one of Doctor Vaughan's afternoon visits, and Olive read it aloud to him, saying at the end, and almost without taking breath,
