Thoreau writes in his journal:
Mr. Derby, whose points of compass I go to regulate, tells me that he remembers when it rained for three weeks in haying time every day but Sundays. Rode to J. Farmer’s . . . Mr. Samuel Hoar tells me that about forty-eight years ago, or some two or three years after he came to Concord, where he had an office in the yellow store, there used to be a great many bullfrogs in the mill-pond . . .
