After the epigaea and the hepatica have opened, there is a slight pause among the wild-flowers,--these two forming a distinct prologue for their annual drama, as the brilliant witch-hazel in October brings up its separate epilogue. The truth is, Nature attitudinizes a little, liking to make a neat finish with everything, and then to begin again with _éclat_. Flowers seem spontaneous things enough, but there is evidently a secret marshalling among them, that all may be brought out with due effect. As the country-people say that so long as any snow is left on the ground more snow may be expected, it must all vanish simultaneously at last,--so every seeker of spring-flowers has observed how accurately they seem to move in platoons, with little straggling. Each species seems to burst upon us with a united impulse; you may search for them day after day in vain, but the day when you find one specimen the spell is broken and you find twenty. By the end of April all the margins of the great poem of the woods are illuminated with these exquisite vignettes. Most of the early flowers either come before the full unfolding of their leaves or else have inconspicuous ones. Yet Nature always provides for her bouquets the due proportion of green. The verdant and graceful sprays of the wild raspberry are unfolded very early, long before its time of flowering. Over the meadows spread the regular Chinese-pagodas of the equisetum, (horsetail or scouring-rush,) and the rich coarse vegetation of the veratrum, or American hellebore. In moist copses the ferns and osmundas begin to uncurl in April, opening their soft coils of spongy verdure, coated with woolly down, from which the humming-bird steals the lining of her nest. The early blossoms represent the aboriginal epoch of our history: the blood-root and the May-flower are older than the white man, older perchance than the red man; they alone are the true Native Americans. Of the later wild plants, many of the most common are foreign importations. In our sycophancy we attach grandeur to the name _exotic_: we call aristocratic garden-flowers by that epithet; yet they are no more exotic than the humbler companions they brought with them, which have become naturalized. The dandelion, the buttercup, duckweed, celandine, mullein, burdock, yarrow, whiteweed, nightshade, and most of the thistles,--these are importations. Miles Standish never crushed these with his heavy heel as he strode forth to give battle to the savages; they never kissed the daintier foot of Priscilla, the Puritan maiden. It is noticeable that these are all of rather coarser texture than our indigenous flowers; the children instinctively recognize this, and are apt to omit them, when gathering the more delicate native blossoms of the woods.
