the summer’s vapor bath
...Thoreau's Journal: 22-July-1851
The season of morning fog has arrived. I think it is connected with dog-days. Perhaps it is owing to the greater contrast between the night and day, the nights being nearly as cold, while the days are warmer? Before I rise from my couch, I see the ambrosial fog stretched over the river, draping the trees. It is the summer’s vapor bath. What purity in the color? It is almost musical; it is positively fragrant. How faery-like it has visited our fields. I am struck by its firm outlines, as distinct as a pillow’s edge, about the height of my house. A great crescent over the course of the river from southwest to northeast. Already 5:30 A.M., some parts of the river are bare. It goes off in a body down the river, before this air, and does not rise into the heavens. It retreats, and I do not see how it is dissipated. This slight, thin vapor which is left to curl over the surface of the still, dark water, still as glass, seems not [to] be the same thing,—of a different quality. I hear the cockerels crow through it, and the rich crow of young roosters, that sound indicative of the bravest, rudest health, hoarse without cold, hoarse with rude health. That crow is all-nature-compelling.; famine and pestilence flee before it. These are our fairest days, which are born in fog.
