August 5.
Every body at Tornea was continually talking to me of a distemper to which their horned cattle are subject, and which kills many of them in the course of the winter, but especially in the spring, when they lose from fifty to a hundred head of cattle almost every year. On walking to examine the meadow into which they are first turned out to grass, I found it a bog or marsh, where the Water Hemlock, Cicuta aquatica, (C. virosa, Sp. Pl. 366. Fl. Lapp. n. 103. Engl. Bot. t. 479.) grew in abundance, and had evidently been cropped plentifully by the animals in feeding. It seemed probable therefore that they eat it most in the spring, when first turned into this pasture; whence it proves so much more extensively fatal than in summer, when perhaps they only pick up a plant here and there. It grows in all the moist meadows which are mown for hay; conse
quently the cattle take it likewise in their winter food, and therefore perish, more or less, during that time of the year. We learn from Wepfer's experiments, who gave it to various kinds of animals, what violent symptoms it occasions. See his book. Nothing appeared to me so interesting, during my visit to Tornea, as to examine into the cause and remedy of this evil. If my ideas be right, the whole might be prevented by employing a woman for a month to eradicate all the Cicuta; by which this town, small as it is, might save above two hundred silver dollars. I was informed that the cattle dying from this cause become so infectious, that they cannot be flayed without great danger. The persons employed in that business have their hands greatly swelled by touching the carcase, and several have lost their lives in consequence. The plant in question, therefore, agrees in qualities with the Œnanthe, as it does likewise in place of growth and outward ap
pearance, especially in the pinnæ of its leaves.[9]
The meadows hereabouts, among the thickets towards the shore of the bay, afforded me the following plants.
1. Veronica (maritima), with an erect stem, branched in the upper part, and
bearing numerous spikes. Lower leaves acute, cordate-oblong, sharply serrated, the upper ones lanceolate, serrated, two, three, or four together, opposite on the stalk. Corolla tubular, divided two thirds of its length into two lips, of which the upper is the broadest, ovate, obtuse, and nearly erect; the lower three-cleft, the middle segment narrowest, but all of equal length. Stamens two, very long, awlshaped, situated at the separation of the two lips. Hence the flower is of the personate kind. Pistil reflexed. Capsule heartshaped, narrow at the upper edge. The flowers are numerous in each spike.
2. Selleri, (Apium graveolens[10],) unless
I am much mistaken. The petals are white, spreading, and acute. The partial umbels are broad. The general one has very rarely one or two (leaves of an involucrum?).
