Topping corn now reveals the yellowing pumpkins. September is at hand.

August 27. 

Saturday. P. M. – To Walden. 

Topping corn now reveals the yellowing pumpkins. 

Dangle-berries very large in shady copses now; seem to love wet weather; have lost their bloom. 

Aster undulatus. 

The decurrent gnaphalium has not long shown yellow. Perhaps I made it blossom a little too early. 

September is at hand; the first month (after the summer heat) with a burr to it, month of early frosts; but December will be tenfold rougher. 

January relents for a season at the time of its thaw, and hence that liquid r in its name.

H. D. Thoreau, Journal, August 27, 1853

Topping corn now reveals the yellowing pumpkins.  See August 28, 1859 ("Pumpkins begin to be yellow."); September 4, 1859 ("Topping the corn, which has been going on some days, now reveals the yellow and yellowing pumpkins. This is a genuine New England scene. The earth blazes not only with sun-flowers but with sun-fruits."); September 18, 1858 ("The earth is yellowing in the September sun.")
