Robins fly in flocks.

August 27. 

P. M. — To Walden. 

Dog-day weather again to-day, of which we had had none since the 18th, — i. e. clouds without rain. 

Wild carrot on railroad, apparently in prime. 
Hieracium Canadense, apparently in prime, and perhaps H. scabrum.

Lactuca, apparently much past prime, or nearly done. 

The Nabalus albus has been out some ten days, but N. Fraseri at Walden road will not open, apparently, for some days yet. 

I see round-leaved cornel fruit on Heywood Peak, now half China-blue and half white, each berry. 

Rhus Toxicodendron there is half of it turned scarlet and yellow, as if we had had a severe drought, when it has been remarkably wet. It seems, then, that in such situations some plants will always assume this prematurely withered autumnal aspect. 

Orchis lacera, probably done some time. 

Robins fly in flocks. 

Apparently Juncus tenuis, some time out of bloom, by depot wood-piles, i. e. between south wood-shed and good apple tree; some fifteen inches high. More at my boat’s shore.

H. D. Thoreau, Journal, August 27, 1858

N. Fraseri at Walden road will not open, apparently, for some days yet. See September 13, 1857 (“Nabalus Fraseri, top of Cliffs, — a new plant, ”); September 23, 1857 (“Varieties of nabalus grow along the Walden road in the woods; also, still more abundant, by the Flint's Pond road in the woods.”)

Cornel fruit on Heywood Peak, now half China-blue and half white, each berry. See August 28, 1856 ("The bright china-colored blue berries of the Cornus sericea begin to show themselves along the river. .”)

Rhus Toxicodendron there is half of it turned scarlet and yellow, as if we had had a severe drought.  See September 30, 1857 (“Rhus Toxicodendron turned yellow and red, handsomely dotted with brown.”)

Orchis lacera, probably done some time. See July 13, 1856 ("Orchis lacera, apparently several days, lower part of spike, willow-row, Hubbard side, opposite Wheildon's land")
