to the earth, no very accurate data can be drawn from this experiment; for different soils will give out their moisture more or less easily, and succulent vegetables be more influenced than those of a drier nature; but it served at the time to indicate the portion of moisture that was escaping from a given horizontal surface. From the invisible and insensible nature of evaporation, its influences are not always considered; but such an action on the surfaces of things as that related above, must put into operation all the inherent powers of matter susceptible of impulse, and probably would produce effects which we might suppose to be accomplished by the agency of other means. Nov. 10.—Many effusions of the mind have been produced by the approach or existence of the seasons of our year, which seem naturally to actuate our bodily or mental feelings through the agency of the eye, or temperature of the air. The peculiar silence that prevails in autumn, like the repose of wearied nature, seems to mark the decline and termination of being in many things that animated our summer months; the singing of the bird is rare, feeble, and melancholy; the hum of the insect is not heard; the breeze passes by us like a sigh from nature: we hear it, and it is gone for ever. But it is the vegetable tribes, which at this season most particularly influence our feeling, and excite our attention. We see the fruits of the earth stored up for our use in that dull season “in which there will be neither earing nor harvest,” the termination and reward of the labors of man. But this day, November 10, presented such a scene of life and mortality, that it could not be passed by without viewing it as an admonition, a display of what has been, and is. There had occurred during the night a severe white frost; and, standing by a green-house filled with verdure, fragrance, and blossom, I was surrounded in every direction by the parents of all this gaiety, in blackness, dissolution, and decay. But the very day before, they had attracted the most merited admiration and delight by the splendor of their bloom and the vigor of their growth; but now just touched by the icy finger of the night, they had become a mass of unsightly ruins and confusion. Once the gay belles of the parterre, they fluttered their hour, a generation of existent loveliness; their youthful successors, unpermitted to mingle with them, peeped from their retreats above, seeming almost to repine at their confinement; they have bloomed their day, another race succeeds, and their hour will be accomplished too. This was so perfectly in unison with the shifting scenes of life, the many changes of the hour, that it seemed inseparably connected with a train of reflection, with the precepts which all nature points out—her still small whisperings for the ears of those that can hear them.
