At no time of year is the weakness of roothold so liable to be fatal to a tree as now. During the winter a gale may snap a tree off at the trunk and smash it bodily to the ground. But if there is no weakness in the trunk there can be none in the roots, for the frost that is set about them holds even the shortest, as if embedded in stone. But now, when the solvent ice has loosened the whole surface for a depth of a foot or more, leaving it fluffy and disintegrated, those trees which have no tap-roots and hold only in this lightened surface are in the greatest danger of uprooting of the whole year. Farmers often clear a shrubby pasture in late March or early April hereabout by taking advantage of this fact. They make a trace-chain fast about the base of a pasture cedar or a stout huckleberry bush, and with a word to the old horse the shrub is dragged from the softened earth, root and all. In mid-summer, after the ground has become compact, this is not to be done.
It is the spring house-cleaning time of the year, when nature is sweeping and picking up, preparatory to laying new carpets and getting new furnishings throughout, and if any of the old furniture of the woodland is not able to stand the strain it has to go to the woodpile. Without the mad March winds the forest would lose much of its fresh virility, the old deadwood would cumber the new growth, and the mild melancholy of decay would prevail as it does in some swamps where sheltering surrounding hills and close growth shunt the gales.
Yet, though house-cleanings are no doubt necessary and beneficient, few of us love them, and we hail with equal joy the resultant cleanliness and the cessation of the uproar. The two days’ gale finally got all the winds of the world piled up somewhere to the southward and ceased, and the piled-up atmosphere drifted back over us, bringing mild blue haze that was like smoke from the fires of summer floating far. All things that had been taut and dense relaxed into dimples or softened into tears. The frost went out of the plowed fields that morning, though the sun was too blurred with the kindly blue mist to have any force. It was just the general relaxation which did it.
Then is apt to come a halcyon day, and though the kingfisher is not here to brood, nor will he be for a month, his fabled weather slips on in advance to cheer us. It may not last a day. March is as mad as April is fickle, and you will need to start early to be sure of it. Then, even if you come home in a snowstorm, you will at least have had a brief glimpse of that sunny softness which is dearer in March than in any other month.
This morning, in that calm which is most apt to settle on the land just before sunrise, the whole woodland seemed to breathe freely and beam in the soft air. The bluebirds caroled all about, and where a few days ago one song sparrow surprised me with his song, a dozen jubilated in the pasture bushes. A half-dozen blackbirds flew over, and though I could not see a single red epaulet in the gray light, and listened in vain for that melodious “kong-quer-ree” which no other bird can sing, I knew them as well by their call of “chut-chuck,” which is equally characteristic.
A flock of goldfinches lighted in the pines with much twittering and suggestions of the summer flight-note of “perchicoree.” But that is no more than they have been doing all winter. In a moment, though, the twittering changed. A melodious note began to come into it, and soon several in the flock were singing rival songs as sweet, though I do not think as loud, as those they will sing when June warmth sets the whole bird world a-choiring. It was a happy note in the cool spring air, for it was more than a spring song. The bluebirds and song sparrows voice that, but the song of the goldfinch is a song of summer, and irresistibly reminds one of fervid June heat and full-leaved trees. It was a warming, winning chorus, and it brought the sun up over the horizon, seemingly with a bound.
In all this joy of early matins I still miss one bird note that surely ought to be heard by now, and that is the robin’s. Robins are here in considerable numbers, but not one of them have I heard sing. I’m afraid the robin is lazy, but, perhaps, it is just his honest, matter-of-fact nature which does not believe in forcing the season. He will sing loud and long enough by-and-by.
Such a spring morning is the best season of the year for moth hunting. The moths are all sound asleep still, tucked away in their cocoons, that are also tucked away in the woodland where it is not so easy to see them in winter. Now the mad March winds have swept the last brown leaves from the bushes, and such moths as hang up there for the winter sleep are easily seen. You may take them home and hang them up wherever you see fit, and you will then be on hand to greet the moth when at his leisure he feels prompted to come forth from his snug sleeping-bag.
I always find more of the spice-bush silk-moth than any others,—perhaps because we both love the same woodland spots, borders of the ponds and streams where the benzoin and sassafras flourish, or upland pastures where the wild cherry hangs out its white racemes in May. They dangle freely in the wind, looking for all the world like a left-over leaf rolled by accident into a rude cylinder. Yet the moth is safe and warm within, rolled up in a silken coat that is firmly glued to the leaf; and not only that, but extends in silky fabric all up along the petiole, and firmly holds it to the twig itself. The mad winds which have scoured the bush clean of all leaves and débris have had no strength which can pluck this “last leaf upon the tree.”
If left to itself it will still hang there a year or two, perhaps more, after the moth has emerged, gradually bleaching to a soft gray, but still clinging. It is a splendid quality of silk, but no one has yet succeeded in reeling or carding it. Callosamia promethia thus escapes becoming a product of the farm rather than the pasture. It is a fine species to have hanging in winter cradles above your mantel, for the imago is large and beautiful, with deep browns and tans softly shading into grays that are tinted with iris, the male being distinct with a body color of deep brown less diversified than the coloring of his mate.
