in Thoreau’s Journal:
There is not now that profusion, and consequent confusion, of events which belongs to a summer walk. There are few flowers, birds, insects, or fruits now, and hence what does occur affects us as more simple and significant, as the cawing of a crow or the scream of a jay. The latter seems to scream more fitly and with more freedom through the vacancies occasioned by fallen maple leaves.
I hear the alarum of a small red squirrel, and see him running by fits and starts along a chestnut bough toward me. His head looks disproportionally large for his body, like a bull-dog’s, perhaps because he has his chaps full of nuts. He chirrups and vibrates his tail, holds himself in, and scratches along a foot as if it was a mile. He finds noise and activity for both of us.
