So every day the old doctor and I hunted the cure-all plant among the mountains and valleys of the Blue Ridge.  Together we toiled up steep heights so slippery with fallen autumn leaves that we had to catch every sapling and branch within our reach to save us from falling.  We waded through gorges and chasms, breast-deep with laurel and ferns; we followed the banks of mountain streams for miles; we wound our way like Indians through brakes of pine—­road side, hill side, river side, mountain side we explored in our search for the miraculous plant.

As the old doctor said, it must have grown scarce and hard to find.  But we followed our quest.  Day by day we plumbed the valleys, scaled the heights, and tramped the plateaus in search of the miraculous plant.  Mountain-bred, he never seemed to tire.  I often reached home too fatigued to do anything except fall into bed and sleep until morning.  This we kept up for a month.

One evening after I had returned from a six-mile tramp with the old doctor, Amaryllis and I took a little walk under the trees near the road.  We looked at the mountains drawing their royal-purple robes around them for their night’s repose.

“I’m glad you’re well again,” she said.  “When you first came you frightened me.  I thought you were really ill.”

“Well again!” I almost shrieked.  “Do you know that I have only one chance in a thousand to live?”

Amaryllis looked at me in surprise.  “Why,” said she, “you are as strong as one of the plough-mules, you sleep ten or twelve hours every night, and you are eating us out of house and home.  What more do you want?”

“I tell you,” said I, “that unless we find the magic—­that is, the plant we are looking for—­in time, nothing can save me.  The doctor tells me so.”

“What doctor?”

“Doctor Tatum—­the old doctor who lives halfway up Black Oak Mountain.  Do you know him?”

“I have known him since I was able to talk.  And is that where you go every day—­is it he who takes you on these long walks and climbs that have brought back your health and strength?  God bless the old doctor.”

Just then the old doctor himself drove slowly down the road in his rickety old buggy.  I waved my hand at him and shouted that I would be on hand the next day at the usual time.  He stopped his horse and called to Amaryllis to come out to him.  They talked for five minutes while I waited.  Then the old doctor drove on.

When we got to the house Amaryllis lugged out an encyclopaedia and sought a word in it.  “The doctor said,” she told me, “that you needn’t call any more as a patient, but he’d be glad to see you any time as a friend.  And then he told me to look up my name in the encyclopaedia and tell you what it means.  It seems to be the name of a genus of flowering plants, and also the name of a country girl in Theocritus and Virgil.  What do you suppose the doctor meant by that?”
