in Thoreau’s Journal:
I go to Fair Haven via the Andromeda Swamps. The snow is a foot and more in depth there still. There is a little bare ground in and next to the swampy woods at the head of Well Meadow, where the springs and little black rills are flowing. I see already one blade, three or four inches long, of that purple or lake grass, lying flat on some water, between snow-clad banks, – the first leaf with a rich bloom on it.
How silent are the footsteps of Spring! …The spring advances in spite of snow and ice and cold even….In warm recesses in meadows and clefts, in rocks in the midst of ice and snow, nay, even under the snow, vegetation commences and steadily advances.
