Let us now proceed to the sundews, first describing the way to their habitation. All the mosses about Manchester possess these curious plants, but Carrington Moss is the most readily accessible, lying only a little distance south-west of Sale. From the station we go for about a mile in the direction of Ashton-upon-Mersey, then turn up one of the lanes upon the left, and look out for a grove of dark fir-trees, which, being close upon the borders of the moss, is an excellent guide. The edge of the moss is being drained and brought under cultivation; all this part, along with the ditches, must be crossed, and the higher, undisturbed portion ascended, and as soon as we are up here we find the objects of our search. Among the heather are numberless little marshes, filled with pea-green _Sphagnum_, and containing often a score or two of the sundews, some of them with round leaves, about a third of an inch across, and growing in flat rosettes of half-a-dozen; others, with long and slender leaves that grow erect. Every leaf is set round with bright red hairs, which spread from it like eyelashes, while similar but shorter hairs cover the surface. When the plant is full-grown and healthy, these hairs exude from their points little drops of sticky and limpid fluid, which, glittering like the diamonds of Aurora, show the reason of the poetical English name, sundew. Directly that any little fly or midge comes in contact with the sticky drops, the unfortunate creature is taken captive, just as birds are caught with bird-lime. Held fast in its jewelled trap, the poor prisoner soon expires; and then, either its juices or the gaseous products of the decomposition, appear to be absorbed by the plant, and thus to constitute a portion of its diet. This is rendered the more probable by the experiments of the late Mr. Joseph Knight, of Chelsea, who fed the large American flycatcher, the _Dionæa_, with fibres of raw beef, and found the plant all the better for its good dinners. Certainly it cannot be asserted positively that the Drosera is nourished by its animal prey, but it is difficult to imagine that so extraordinary and successful an apparatus is given to these plants for the mere purpose of destroying midges, and that the higher purpose of food is not the primary one. On the larger leaves may generally be seen relics of the repast, shrivelled bodies, wings, and legs, reminding one of the picked bones that strew the entrance to the giant's cavern in the fairy tale. Sundew plants may be kept in a parlour, by planting them in a dishful of green moss, which must be constantly flooded with water, and covering the whole with a glass shade. Exposed to the sunshine, their glittering drops come out abundantly, but the redness of the hairs diminishes sensibly, owing, perhaps, to their being denied their natural prey. The flowers of these singular plants are white, and borne on slender stalks that rise to the height of three or four inches. The roots survive the winter.
