the habit of carrying a book with her on
the long drives, though she often left it untouched while she walked
up and down the country roads, or even ventured upon excursions as far
afield as she dared, while the doctor made his visit, which was apt to
be a long one in the lonely country houses. This morning she had
possessed herself of a square, thin volume which gave lists and plates
of the nerve system of the human body. The doctor had nearly laughed
aloud when he caught sight of it, and when Nan opened it with decision
and gravity and read the first page slowly, she was conscious of a
lack of interest in her subject. She had lost the great enthusiasm of
the night before, and felt like the little heap of ashes which such a
burning and heroic self might well have left.

Presently she went strolling down the road, gathering some large
leaves on her way, and stopped at the brook, where she pulled up some
bits of a strange water-weed, and made them into a damp, round bundle
with the leaves and a bit of string. This was a rare plant which they
had both noticed the day before, and they had taken some specimens
then, Nan being at this time an ardent botanist, but these had
withered and been lost, also, on the way home.

Dr. Leslie was in even less of a hurry than usual, and when he came
out he looked very much pleased. "I never was more thankful in my
life," he said eagerly, as soon as he was within convenient distance.
"That poor fellow was at death's door yesterday, and when I saw his
wife and little children, and thought his life was all that stood
between them and miserable destitution, it seemed to me that I _must_
save it! This morning he is as bright as a dollar, but I have been
dreading to go into that house ever since I left it yesterday noon.
They didn't in the least know how narrow a chance he had. And it isn't
the first time I have been chief mourner. Poor souls! they don't dread
their troubles half so much as I do. He will have a good little farm
here in another year or two, it only needs draining to be excellent
land, and he knows that." The doctor turned and looked back over the
few acres with great pleasure. "Now we'll go and see about old Mrs.
Willet, though I don't believe there's any great need of it. She
belongs to one of two very bad classes of patients. It makes me so
angry to hear her cough twice as much as need be. In your practice,"
he continued soberly, "you must remember that there is danger of
