Henry David Thoreau: Walden

17. Spring (continued)

One attraction in coming to the woods to live was that I should have leisure and opportunity to see the Spring come in. The ice in the pond at length begins to be honeycombed, and I can set my heel in it as I walk. Fogs and rains and warmer suns are gradually melting the snow; the days have grown sensibly longer; and I see how I shall get through the winter without adding to my wood-pile, for large fires are no longer necessary. I am on the alert for the first signs of spring, to hear the chance note of some arriving bird, or the striped squirrel's chirp, for his stores must be now nearly exhausted, or see the woodchuck venture out of his winter quarters. On the 13th of March, after I had heard the bluebird, song sparrow, and red-wing, the ice was still nearly a foot thick. As the weather grew warmer it was not sensibly worn away by the water, nor broken up and floated off as in rivers, but, though it was completely melted for half a rod in width about the shore, the middle was merely honeycombed and saturated with water, so that you could put your foot through it when six inches thick; but by the next day evening, perhaps, after a warm rain followed by fog, it would have wholly disappeared, all gone off with the fog, spirited away. One year I went across the middle only five days before it disappeared entirely. In 1845 Walden was first completely open on the 1st of April; in '46, the 25th of March; in '47, the 8th of April; in '51, the 28th of March; in '52, the 18th of April; in '53, the 23d of March; in '54, about the 7th of April.
