The forest generally is not yet changed.

October 1. 

Friday. Surveying in Lincoln. 

A severer frost last night. 

The young and tender trees begin to assume the autumnal tints more generally, plainly in consequence of the frost the last two mornings.

The sides of the bushy hills present a rich variety of colors like rug work, but the forest generally is not yet changed.

H. D. Thoreau, Journal, October 1, 1852

A severer frost last night. The young and tender trees begin to assume the autumnal tints. See October 1, 1853 ("Grapevines, curled, crisped, and browned by the frosts, are now more conspicuous than ever"); October 1, 1857 ("After the maples have fairly begun, the young red oaks, ash trees, etc., begin with the first smart frost. ");  October 1, 1860 ("Remarkable frost and ice this morning.")

The young and tender trees begin to assume the autumnal tints more generally.. . .but the forest generally is not yet changed. See October 1, 1856 ("Maples mixed with the evergreen pines, at the base of a pine-clad hill, and see their yellow and scarlet and crimson fires of all tints, mingled and contrasted with the green"). See also September 29, 1853 ("Sumachs and maples changed, but not trees generally."); October 2, 1857 ("Generally speaking, it is only the edge or pediment of the woods that shows the bright autumnal tints yet"); October 3, 1856 ("Especially the hillsides about Walden begin to wear these autumnal tints in the cooler air"); October 6, 1858 ("Now, methinks, the autumnal tints are brightest in our streets and in the woods generally. "); October 13,1852 ("The autumnal tints have already lost their brightness. It lasts but a day or two."); October 13, 1857 ("Those most brilliant days, then, so far as the autumnal tints are concerned, are over."); October 23, 1852 (" By the end of the month the leaves will either have fallen or besered and turned brown by the frosts for the most part.
