It rarely happens that any of the works of nature are wholly productive of evil; and even the crows, troublesome as they are, contribute in a small degree to the good of the district they frequent. Thus, though they destroy eggs and young poultry, plunder the corn-fields, and carry off whatever may serve for food, they also rid the surface of the earth of a considerable quantity of carrion, and a vast multitude of insects and their destructive larvæ. The crows are very usefully employed when they alight upon newly-ploughed fields, and pick up great numbers of those large and long-lived worms which are so destructive to the roots of all growing vegetables; and they are scarcely less so when they follow the seine-haulers along the shores, and pick up the small fishes, which would otherwise be left to putrefy, and load the air with unpleasant vapours. Nevertheless, they become far more numerous in some parts of the country than is at all necessary to the good of the inhabitants, and whoever would devise a method of lessening their numbers suddenly, would certainly be doing a service to the community. About a quarter of a mile above the house I lived in, on Curtis's creek, the shore was a sand-bank or bluff, twenty or thirty feet high, crowned with a dense young pine-forest to its very edge. Almost directly opposite, the shore was flat, and formed a point, extending, in the form of a broad sand-bar, for a considerable distance into the water; and, when the tide was low, this flat afforded a fine level space, to which nothing could approach in either direction without being easily seen. At a short distance from the water, a young swamp-wood of maple, gum, oaks, etc. extended back towards some higher ground. As the sun descended, and threw his last rays in one broad sheet of golden effulgence over the crystal mirror of the waters, innumerable companies of crows arrived daily, and settled on this point, for the purpose of drinking, picking up gravel, and uniting in one body prior to retiring for the night to their accustomed dormitory. The trees adjacent and all the shore would be literally blackened by these plumed marauders, while their increasing outcries, chattering, and screams, were almost deafening. It certainly seems that they derive great pleasure from their social habits; and I often amused myself by thinking the uninterrupted clatter which was kept up, as the different gangs united with the main body, was produced by the recital of the adventures they had encountered during their last marauding excursions. As the sun became entirely sunk below the horizon, the grand flock crossed to the sand-bluff on the opposite side, where they generally spent a few moments in picking up a farther supply of gravel, and then, arising in dense and ample column, they sought their habitual roost in the deep entanglements of the distant pines. This daily visit to the point, so near to my dwelling, and so accessible by
