Thoreau writes in his journal:
She [Mrs. Hamilton] said the wild [crab?] apple grew about her premises. Her husband 1st saw it on a ridge by the lake shore. They had dug up several & set them out, but all died. (The settlers also set out the wild plum & thimble berry &c.). So I went & searched in that very unlikely place, but could find nothing like it, though Mrs. Hamilton said there was on ether 3 feet higher than the lake. But I brought home a thorn in bloom instead & asked if that was it. She then gave me more particular directions & I searched again faithfully. & this time I brought home an Amelanchier as the nearest of kin, doubting if the apple had ever been seen there. But she knew both these plants. Her husband had first discovered it by the fruit. But she had not seen it in bloom here. Then called on Fitch & talked about it. He said it was found—the same they had in Vermont (?) & directed me to a Mr. [Jonathan T.] Grimes as one who had found it. He was gone to catch the horses to send his boy 6 miles for a doctor on account of the sick child. Evidently a [?] and enquiring man. The boy showed me some of the trees he had set out this spring. But they had all died, having a long tap root & being taken up too late. But then I was convinced by the sight of the just expanding though withered flower bud to analyze. Finally stayed & went in search of it with the father in his pasture, where I found it first myself, quite a cluster of them.
