Concord, Mass. Thoreau writes in his journal:
This afternoon, being on Fair Haven Hill, I heard the sound of a saw, and soon after from the Cliff saw two men sawing down a noble pine beneath, about forty rods off. I resolved to watch it till it fell . . . It towered up a hundred feet as I afterward found by measurement, one of the tallest probably in the township and straight as an arrow, but slanting a little toward the hillside, its top seen against the frozen river and the hills of Conantum . . .
I went down and measured it. It was about four feet in diameter where it was sawed, about one hundred feet long. Before I had reached it the axemen had already half divested it of its branches.

Cocord, Mass. Thoreau writes in his journal, probably on 1 January 1852, though the entry is dated 31 December 1851:
The pine I saw fall yesterday [meaning 30 December] measured to-day one hundred and five feet, and was about ninety-four years old. There was one still larger lying beside it, one hundred and fifteen feet long, ninety-six years old, four feet diameter the longest way.
