Little obstructs your passage, now that the firm ice is underfoot, unless it is the too close set tree trunks. Goldthread and partridge berry creep in the moss that mounds about the very stumps of the cedars, but no other vine or shrub seems to have the vitality to grow here, or if it had it has wisely used it to flee to more sunny uplands. Not even in tropical jungles have I seen the struggle for existence so fierce as it is among these too closely set swamp cedars. One in ten eventually survives and makes a marketable growth. Other things bring them to disaster than the choking crowding of their neighbors, however. Here and there you can see big trees that lurch in strange fashion, some this way and some that. This is most often true of a pine that by some chance has grown among them. The cause is the uncertain footing of the slimpsy bog. As they get heavier and taller they cannot find sufficient anchorage in the yielding wallop beneath their roots, and sooner or later a wind comes that tips them over. But I found in places among the sheltering larger trees, groups of young ones, cedars, that could have suffered from no wind, they were so well protected and walled round by their elders. These were laid down in brief windrows all in the same direction, and I wonder still what force accomplished it. If it had been a tropical jungle I should have said that here a hippopotamus wandered up out of the depths and back again, or here an elephant fled from some retired statesman, but these are not beasts of our frozen forests.
In one place was another tropical suggestion that was a bit startling. This was the cast skin of a snake that must have been four inches in diameter. It was only the white bark of a dead birch that had fallen and rotted, as to its heart-wood, all away, but the tougher bark remained, dangling in white folds just as a snake’s skin does when cast.
But this is not the place to see the swamp cedars at their best. You are on their gloomy side now. Toward the vivifying sun they turn every cheerful atom within them and as you look down on them as the sun does from some near by southern ridge you get the full effect of their close-set masses of living green and realize the enormous virility within them. It seems to me that our toughest tree here in eastern Massachusetts is the red cedar. It grows on storm-swept rock cliffs where nothing else but lichens can seem to find a foothold. Yet close behind it I class this dweller in the rich, moist peat bogs. I find that many botanists do not differentiate this tree that I call swamp cedar from the red cedar, Juniperus virginiana. Yet it is nearer this than it is to the arbor vitæ which is the so-called cedar of the Maine woods. But it is not the red cedar in one important particular. It does not have that wonderful red fragrant heart-wood that the red cedar has. That alone, it seems to me, should give it a separate standing botanically. Then its leaves are flatter and more of the arbor vitæ type than those of the red cedar. And there you have it; but I know what happened. Long ages ago, when staid and sober evergreens were more frisky than they are now some particularly handsome young arbor vitæ lass came down from the north woods and met and loved one of our husky red cedars. How could she help it? Then there was a secret trip to Providence, or whatever place was the Gretna Green of those days, and the elopers settled down in Plymouth County, or perhaps here in Norfolk. That would account for my white cedar, and it is the only way I can do it.
I was two miles further toward the Plymouth woods and was broiling a chop for my dinner on the fork of a witch-hazel stick over the lovely clear flame of dry white pine limbs, when I came across the second new thing of my experience in the winter woods. That was black snow. It was on the northerly edge of an open meadow, a spot so tangled with wild rose and other slender shrubs that it was next to impossible to penetrate it. For some reason the south wind had failed to carry off all the snow here, and a thin coating of it lay on the ground. There was a bit of open water on the edge of the tangle, and I noticed that this was covered with a black coating. Going down to look closer I found that the snow as far as I could look into the meadow was covered with this same surface, making it fairly black. It looked quite like the soot from black coal, but when I poked at it with my finger to see if it smutted it hopped nimbly away. The open pool and the snow all about it was covered with tiny black fleas or some similar skipping minute insect. I was curious about these tiny black creatures, and I folded many of them carefully in a leaf of my note book, creasing the edges firmly so that I might keep them tight, and put them in my scrip. I intended to put them under a microscope and see how many legs they had for all this wonderful skipping; but they had too many for me. When I got home the paper was blank. They had all skipped.
AMONG THE MUSKRAT LODGES
I ALWAYS know the sound of the east wind as it comes over the Blue Hills for the twanging of the bow from which winter has shot his Parthian arrow. The keenest it is in all his quiver of keen darts, for it penetrates joints in one’s armor that no gale from Arctic barrens has been able to reach, that no fall of snow or of temperature has weakened. Facing it to-day and feeling its barbs turn in the marrow of my breastbone as I crossed Ponkapoag Pond I began to wonder how it fared with my friends the muskrats who were wintering in the very teeth of it over on the northwest shore. And so I turned my shoulder to the blow and my face to the bog where tepees in a long line spire conically out of the brown grasses on the bog edge, where the pickerel weed flaunted blue banners all summer long.
