Thoreau writes in his journal:
P.M.—Walking up the river by Pritchard’s, was surprised to see, on the snow over the river, a great many seeds and scales of birches, though the snow has so recently fallen, there had been but little wind, and it was already spring… The opening in the river at Merrick’s is now increased to ten feet in width in some places . . .
