These looked so tiny as compared with the mature ferns, but were so erect and confident, so fresh and green and very much alive though the temperature about them night after night had been far below freezing and their roots then stood in ice, that it was worth a journey, just to look at them. How their tender tissues had stood the temperature of ten above zero that had surrounded them a few nights before is more than I can answer. The faintest touch of frost kills the fronds of the great seemingly tough cinnamon and ostrich ferns. Yet these dainty little plants of _Nephrodium spinulosum_ with their miniature fronds of tender lacework had not even wilted or cowered before deep and continued cold as had the stalks of their elders of the same species, but stood erect, nonchalant and seemingly eagerly growing still. We may say if we will that it is all a part of that magic of youth that makes a million miracles each spring but that does not explain it. Why should these be so strong and full of life when the fronds of the hay-scented fern, for instance, have been shrivelled to dry and crumbling brown fragments under the same conditions? I cannot answer this either. Last of all I thought of the polypodys that grow in the rock crevices all down along the glen, and went to see how they fared. It has been a hard year for these little fellows. There must have been weeks at a time during the scorching days of the long summer’s drought that their roots, clinging precariously in rock crevices and dependent for moisture wholly on rain and dew, were dry to the tips. The very heat of the rock itself under the blister of the sun would not only evaporate all moisture, but would so remain in the rock all night as to prevent any dew from condensing on it. I had seen the polypodys at midday curled up on themselves seemingly nothing but dried tissues that could never be again infused with the breath of green life. Yet, let there come but the briefest of showers and you would see them uncurl, lift their fronds to the breeze, and go on as cheerily as their lower level neighbors the lady-ferns whose pinnules flashed in the drip of the splashing stream and whose roots bathed in the shallows. The summer must have weakened them. Were they the sort to shrivel at the touch of the freezing wind and vanish into the fern-seed magic of invisibility? Not they. The slender crevice of black dirt in which their roots grow was black adamant with frost, but the polypodys swayed in the biting wind as jauntily as they had in the soft airs of summer and were as green and unharmed by the winter thus far as the Christmas ferns had been. While I gazed at them, admiring their toughness and courage, my eye caught a bit of greenery on the rock high above and I had found the second unexpected fern of my winter day’s hunt, for there from a crevice dripped the rounded, finely crenate, dark green pinnæ of _Asplenium trichomanes_, the maidenhair spleenwort.
