Concord, Mass. Thoreau writes in his journal:
Quite a sultry, cloudy afternoon,—hot walking in woods and lowland where there is no air . . .
Examine Tarbell’s pitch pine grove. This is all of one age and very dense. The largest trees on the north side, as estimated by sawing a branch, are twenty-eight to thirty years old. Tarbell says this grove came up in 189-6 on land which had been burnt over,—in fact open land . . .
Cambridge, Mass. Welch, Bigelow & Company writes to Thoreau:
Dear Sir
Please send us another installment of Black Lead as before. Only you should pay express chg. to Boston as heretofore with the exception of the last
Yours truly
Welch Bigelow & Co
