The farmers say a deep snow draws the frost out of the ground. It is certain that the frost goes out when the ground is deeply covered for some time, though it is of course the warmth rising up from the depths of the ground that does it. A winter of deep snows is apt to prove fatal to the peach buds. The frost leaves the ground, the soil often becomes so warm that angle-worms rise to near the surface, the sap in the trees probably stirs a little; then there comes a cold wave, the mercury goes down to ten or fifteen below zero, and the peach buds are killed. It is not the cold alone that does it; it is the warmth at one end and the extreme cold at the other. When the snow is removed so that the frost can get at the roots also, peach buds will stand fourteen or fifteen degrees below zero.
March 7, 1881. A perfect spring day at last,—still, warm, and without a cloud. Tapped two trees; the sap runs, the snow runs, everything runs. Bluebirds the only birds yet. Thermometer forty-two degrees in the shade. A perfect sap day. A perfect sap day is a crystalline day; the night must have a keen edge of frost, and the day a keen edge
of air and sun, with wind north or northwest. The least film, the least breath from the south, the least suggestion of growth, and the day is marred as a sap day. Maple sap is maple frost melted by the sun. (9 P. M.) A soft, large-starred night; the moon in her second quarter; perfectly still and freezing; Venus throbbing low in the west. A crystalline night.
March 21, 1884. The top of a high barometric wave, a day like a crest, lifted up, sightly, sparkling. A cold snap without storm issuing in this clear, dazzling, sharp, northern day. How light, as if illuminated by more than the sun; the sky is full of light; light seems to be streaming up all around the horizon. The leafless trees make no shadows; the woods are flooded with light; everything shines; a day large and imposing, breathing strong masculine breaths out of the north; a day without a speck or film, winnowed through and through, all the windows and doors of the sky open. Day of crumpled rivers and lakes, of crested waves, of bellying sails, high-domed and lustrous day. The only typical March day of the bright heroic sort we have yet had.
March 24, 1884. Damp, still morning, much fog on the river. All the branches and twigs of the trees strung with drops of water. The grass and weeds beaded with fog drops. Two lines of ducks go up the river, one a few feet beneath the other. On second glance the under line proves to be the reflection of the other in the still water. As the
ducks cross a large field of ice, the lower line is suddenly blotted out, as if the birds had dived beneath the ice. A train of cars across the river,—the train sunk beneath a solid stratum of fog, its plume of smoke and vapor unrolling above it and slanting away in the distance; a liquid morning; the turf buzzes as you walk over it.
Skunk cabbage on Saturday the 22d, probably in bloom several days. This plant always gets ahead of me. It seems to come up like a mushroom in a single night. Water newts just out, and probably piping before the frogs, though not certain about this.
March 25. One of the rare days that go before a storm; the flower of a series of days increasingly fair. To-morrow, probably, the flower falls, and days of rain and cold prepare the way for another fair day or days. The barometer must be high to-day; the birds fly high. I feed my bees on a rock, and sit long and watch them covering the combs, and rejoice in the multitudinous humming. The river is a great mirror dotted here and there by small cakes of ice. The first sloop comes lazily up on the flood tide, like the first butterfly of spring; the little steamer, our river omnibus, makes her first trip, and wakes the echoes with her salutatory whistle, her flags dancing in the sun.
April 1. Welcome to April, my natal month; the month of the swelling buds, the springing grass, the first nests, the first plantings, the first flowers, and, last but not least, the first shad! The door of
the seasons first stands ajar this month, and gives us a peep beyond. The month in which to begin the world, in which to begin your house, in which to begin your courtship, in which to enter upon any new enterprise. The bees usually get their first pollen this month and their first honey. All hibernating creatures are out before April is past. The coon, the chipmunk, the bear, the turtles, the frogs, the snakes, come forth beneath April skies.
