As the vivid hues of the red maple fade in the swamp and are replaced by the soft silvery gray and purplish sheen of the bark, the oaks on the hillside become ruddy. The coloring is rich and subdued, rather than brilliant and glowing as at first--mahogany and maroon set off by the purple mists of Indian summer. And now at last branches are bare and leaves rustle underfoot.
In New England pastures, the boulders are as much in harmony with their environment as any tree or shrub. They have the appearance of having grown here, quite as naturally as the bayberry and the sweet fern, and are kindred of the savin, and the low-spreading juniper which circles round them and hugs the stone like the lichen itself. The migrant boulders from the North are congenial to these hardy northern plants which reflect the somber character of the rock.
A field that has been entirely cleared of its pasture stones and left to stand thus, somehow looks barren and deserted. You feel you would like to restore a boulder here and there and invite the juniper and the bayberry to return. There is character in these ancient pasture stones, and they cannot be removed without depriving the landscape of that which they imparted; it is no longer virile and forceful, but tame and meek as though shorn of its strength.
If you would build your house on truly historic ground, lay it on foundation of pasture stones, and incorporate, as it were, Time itself into the structure. This is to let the very elements work for you. On many a farm the boulders are as good a crop as any; when they are gathered into the walls to give room for one more lucrative, this value at least of the farm is still represented. The fields have produced but one crop of boulders, and only the ages could mature this. If the pastures must lose this ancient beauty, let the house gain by it. Build it into your chimney. Take it to your hearth that it may not be lost. Let the boulder tell its story by the light of the hickory logs.
There is a rustic notion that boulders somehow _grow_, in some inexplicable manner enlarging like puff balls and drawing sustenance from the earth--and what could be more puzzling to the uninitiated than the presence of these pasture stones? His was an ingenious mind who conjured up that remote ice age from this fragmentary evidence and derived a history from these scattered letters and elliptical sentences. It was like tracing the stars to their origin.
