Thoreau writes in his journal:
Is the shrub with yellow blossoms which I found last week near the Lincoln road while surveying for E. Hosmer and thought to be Xylosteum ciliatum, or fly honeysuckle, the same with the yellow diervilla which I find in Laurel Glen to-day? . . . I see that Dugan has trimmed off and peeled the limbs of the willows on the Turnpike to sell at the Acton powder-mill . . . As I walk the railroad causeway, I notice that the fields and meadows have acquired various tinges as the season advances, the sun gradually using all his paints.
