The moon appears full. At first a mere white cloud. As soon as the sun sets, begins to grow brassy or obscure golden in the gross atmosphere. It is starlight about half an hour after sunset to-night; i. e. the first stars appear. The moon is now brighter, but not so yellowish. Ten or fifteen minutes after, the fireflies are observed, at first about the willows on the Causeway, where the evening is further advanced. Sparrows quite generally, and occasionally a robin sings. (I heard a bobolink this afternoon.) The creak of the crickets is more universal and loud, and becomes a distinct sound. The oily surface of the river in which the moon is reflected looks most attractive at this hour. I see the bright curves made by the water-bugs in the moonlight, and a muskrat crossing the river, now at 9 o’clock. Finally the last traces of day disappear, about 9:30 o’clock, and the night fairly sets in. The color of the moon is more silvery than golden, or silvery with a slight admixture of golden, a sort of burnished cloud.
