"On this estate these things had never been dreamt of before planting the orchards. The apple-tree, in short, as soon as its branches and leaves spread with the morbid growth of a dozen years, aids itself in the destructive process; the soil becomes yearly more poisonous, the roots soon decay, and the tree falls to one side, as we witness daily, while the herbage beneath and around becomes daily more unfit to sustain animal life. Numerous forms of poisonous fungi, microscopic and otherwise, are here at home, and nourished by the carburetted and other forms of hydrogen gas hourly engendered and saturating the soil; while on the dampest spots the less noxious portions of such hydrates are assimilated by the mint plant in the shape of oil; and which disputes with sour, poisonous, and blossomless grasses for the occupancy of the surface, mingled with the still more noxious straggling forms of the ethusa, occasionally the angelica, vison, conium, &c. "This state of things, brought into existence by this wretched and barbarous mode of planting orchard valleys, usually reaches its consummation in about thirty years, and sometimes much less, as in the valley under notice. Thus it is that such spots, often the richest in capabilities on the estate, (the deep soil being the waste and spoil of the higher ground and slopes,) become a bane to every form of useful vegetation; and, at the same time, are a hotbed of luxuriance to every thing that is poisonous, destructive, and deleterious to almost every form of animal life. And such an animal as the sheep, while feeding among such herbage, would inhale a sufficiency of noxious gases, especially in summer, through the nostrils alone, to produce disease even in a few hours, though the herbage devoured should lie harmless in the stomach. But with regard to the sheep in the present case, we fear they had no choice in the matter, and were driven by hunger to feed, being shut into these orchards; and thus not only ate the poisoned grasses, but with every mouthful swallowed a portion of the water-engendering mint, the acrid crowfoot, ranunculus leaves, &c., surrounding every blade of grass; while the other essential elements of vegetable poison, the most virulent forms of agarici and their spawn, with other destructive fungi, were swallowed as a sauce to the whole. This fearful state of things, to which sheep had access, soon manifested its results; for although a hog or a badger might here fatten, yet to an animal so susceptible to atmospheric influences, unwholesome, undrained land, &c., as the sheep, the organization forbids the assimilation of such food; and although a process of digestion goes on, yet its hydrous results (if we may use such a term) not only overcharge the blood with serum, but, through unnatural channels, cause effusion into the chest, heart, veins, &c., when its effects are soon manifested in sudden and quick dissolution, being found dead in the attitude of sleep."
