THE MINK’S HUNTING GROUND
I WISH I could have seen the country about the great spring which goes by the name, locally, of “Fountain Head” the year that the clock stopped for the glaciers hereabout. That year when the last bit of the ice cap, that for ages had slid down across southeastern Massachusetts and built up its inextricable confusion of sand and gravel moraines, melted away, would have shown a thousand great springs like it, bubbling up all through the region, almost invariably from the northerly base of gravelly cliffs over which the sun can hardly peep at noonday, so steep they are. Here they flow to-day in the same mystery. Why should these unfailing springs rush forth so steadily, be the weather hot or cold, or the drought never so long or so severe? Why should their temperature like their flow be changeless, summer or winter?
I sometimes believe that their waters filter through deep caverns from far Arctic glaciers continually renewed. Perhaps to have looked at them before the changing seasons of more thousands of years had clothed the gravel and sand with humus, grown the forests all about and choked the fountains themselves with acres of the muck of decayed vegetation no one knows how deep, would have been to see them with clearer eyes and have been led to an answer to the questions. Now I know them only as bits of the land where time seems to have stood still, fastnesses where dwell the lotus eaters of our New England woods, where winter’s cold howls over their heads, but does not descend, and where summer’s heat rims them round, but hardly dares dabble its toes in their cool retreat.
Progress has built its houses on the hills about them, freight trains two miles away roar so mightily that the quaggy depths tremble with the vibrations, and you may sit with the arethusas in mossy muck and hear the honk of the automobile mingling with that of the wild geese as they both go by in spring. Yet the one makes as much impression on the land and its inhabitants as the other. The lotus eaters know not Ulysses; if he wants them for his ships of progress he must capture them by force and tie them beneath the rowers’ benches, else they return. Even the temperature of those last days of the ice cap seems to have got tangled in the spell and to dwell with the mild-eyed melancholy of the place the year round. In midsummer the thermometer may stand at 120 in the quivering nooks where the sun beats down upon the sandy plains above; the waters of the fountain head are ice cold still, and give their temperature to the brook and its borders. In midwinter the mercury may register twenty below, and the gales from the very boreal pole freeze the pines on those same sandy plains till their deep hearts burst; the waters that flow from those mysterious fountains will have no skim of ice on their surface.
From what unfathomed depths the waters draw their constancy we may never know, nor on what day may well forth with them some new form of life bred on the potency of their elixir. To-day is freezing cold and now and then snow-squalls whirl in among the swamp maples, eddying in flocks as the goldfinches do, yet the surface of the biggest pool where the waters well up is covered with the vivid green of new plant life. Millions of tiny boreal creatures swim free on the cool surface, plants reduced to their simplest terms, born for aught I know in depths below like those
“Where Alph, the sacred river, ran
Through caverns measureless to man
Down to a sunless sea,”
whence they ooze in the seeping of the upward current to our shores. No one has here found the seeds of these stemless pinheads of green that lie flat on the surface and send down for a wee fraction of an inch their two or three tiny root hairs into the water.
No one can say they are apetalous or monosepalous or sporangiferous or call them other hard names in Latin having reference to their flowering or fruiting for we may not say that they flower or fruit at all. These minutest Lemnas give us no sign of stamin or spore, of carpel or indusium, yet they multiply by millions and cover the surface of the spring pools whence they depart constantly with the outflowing current, voyaging gayly down Brobdingnagian rapids to the sea. The time of year when it is winter in the sky above and on the bank a few feet up the hillside, when all green life except that which grows with its roots in this magic water from the deep caves of earth is either killed or suspended, seems to be their time for growth.
