"... those icebergs vast, With heads all crowned with snow, Whose green roots sleep in the awful deep, Two hundred fathoms low." But prettier than these Arctic mosses are those nearer home. Talking about them makes me think of a place where I wish you and I could go together some beautiful afternoon in winter. It is a lovely little pine-wood near Bournemouth, to which some boys, with whose friends I was staying during the Christmas holidays, wished to take me to see their favourite walk. [Illustration: ICE-BOUND] Once when we were starting for our run, on a bright frosty morning, and I was rather hoping I should be taken to the sea, I heard them say to each other, "The Pincushion Wood; that's it; do let us go there." I wondered what kind of place this could be but when we had scrambled through some heather and come to this pine-wood, I saw at once why they had given it its name. Overhead, with their needles against the blue sky, were the pines in their dark solemn green, but under our feet the ground was bright with moss which grew, not on stones or trunks of trees, but all by itself in round balls, soft and firm and cushiony. You may be sure I was delighted with the green pincushions: we gathered a quantity of them, and I took one home with me, but though I watered it carefully, it soon lost its beauty. These moss-balls lay at the roots of the pines, and we could pick up as many as we pleased; but generally even the most delicate mosses grasp the soil, and clasp their soft tendrils round the stones so firmly that you need a knife or a sharp stone to make them loose their hold. One of the uses of moss is to protect the rocks from the frost, and from the heavy rains which wash them away by degrees. The roots of trees, too, are cherished and warmed by the closely clinging mosses; and by holding the moisture from dew and rain, they form where they grow a little bed of soft mould, and so prepare the way for plants of larger growth. Do you know the Trumpet-moss, with its red cups each holding its own little dewdrop? Perhaps not, for it is a rare treasure, and needs to be sought for in its own haunts; but there are many green mosses which are very beautiful, and so common that we see them upon every garden wall. There is the Hair-moss, the seeds of which are eaten by the birds, while its delicate tendrils serve as soft lining for their nests: it grows plentifully beside our streams; but far away in Lapland, during the short summer when the flowers all at once burst into bloom, it may be seen in full beauty. The Laps cut this moss in layers and dry it in the sun, to form a soft rug for them to sleep under during their cold nights. Then there is the velvety moss which, like the many-coloured lichen, loves to creep over old buildings, and make the ruined and desolate places bright with a beauty not their own.
