In those parts of the Highlands of Scotland where eagles are numerous, and where they commit great ravages among the young lambs, the following methods are used for destroying them:—When the nest happens to be in a place situated in the direction of a perpendicular from the edge of a cliff above, a bundle of dry heath or grass inclosing a burning peat is let down into it. In other cases, a person is let down by means of a rope, which is held above by four or five men, and contrives to destroy the eggs or young. The person who thus descends takes a large stick with him, to beat off or intimidate the old eagles. The latter, however, always keep at a respectable distance, for powerful as they are, they possess little of the courage which has in all ages been attributed to them, being in this respect much inferior to the domestic cock, the raven, the sea-swallow, and a hundred other birds. Sometimes eagles have their nests in places accessible without a rope, and instances are known of persons frequenting these nests, for the purpose of carrying off the prey which the eagles carry to their young. A very prevalent method by which eagles are destroyed, is the following:—In a place not far from a nest, or a rock in which eagles repose at night, or on the face of a hill which they are frequently observed to scour in search of prey, a pit is dug to the depth of a few feet, of sufficient size to admit a man with ease. The pit is then covered over with sticks, and pieces of turf, the latter not cut from the vicinity, eagles, like other cowards, being extremely wary and suspicious. A small hole is formed at one end of this pit, through which projects the muzzle of a gun, while at the other is left an opening large enough to admit a featherless biped, who on getting in pulls after him a bundle of heath of sufficient size to close it. A carcass of a sheep or dog, or a fish or fowl, being previously without at the distance of from twelve to twenty yards, the lyer-in-wait watches patiently for the descent of the eagle, and, the moment it has fairly settled upon the carrion, fires. In this manner, multitudes of eagles are yearly destroyed in Scotland. The head, claws, and quills, are kept by the shepherds, to be presented to the factor at Martinmas or Whitsunday, for the premium of from half-a-crown to five shillings which is usually awarded on-such occasions.—Edinburgh Literary Gazette.

THE PIED OYSTER CATCHER

This separate and single genus of birds is seldom seen amongst the numerous descriptions of wild fowl, which, in the winter seasons, wing their flight to our marshes. The most striking part of the Oyster-catcher is its bill, the colour of which is scarlet, measuring in length nearly four inches, wide at the nostrils, and grooved beyond them nearly half its length: thence to the tip it is vertically compressed on the sides, and ends obtusely. With this instrument, which in its shape and structure is peculiar to this bird, it easily disengages the limpets from the rocks, and plucks out the oysters from their half-opened shells, on which it feeds, as well as on other shell-fish, sea-worms, and insects.

BUTTERFLIES

The splendid appearance of the plumage of tropical birds is not superior to what the curious observer may discover in a variety of Lepidóptera; and those many-coloured eyes, which deck so gorgeously the peacock's tail, are imitated with success in Vanéssa Io, one of our most common butterflies. "See," exclaims the illustrious Linnaeus, "the large, elegant, painted wings of the butterfly, four in number, covered with small imbricated scales; with these it sustains itself in the air the whole day, rivalling the flight of birds, and the brilliancy of the peacock. Consider this insect through the wonderful progress of its life, how different is the first period of its being from the second, and both from the parent insect. Its changes are an inexplicable enigma to us: we see a green caterpillar, furnished with sixteen feet, creeping, hairy, and feeding upon the leaves of a plant; this is changed into chrysalis, smooth, of a golden lustre, hanging suspended to a fixed point, without feet, and subsisting without food; this insect again undergoes another transformation, acquires wings and six feet, and becomes a variegated white butterfly, living by suction upon the honey of plants. What has nature produced more worthy of our admiration? Such an animal coming upon the stage of the world, and playing its part there under so many different masks! In the egg of the Papilio, the epidermis or external integument falling off, a caterpillar is disclosed; the second epidermis drying, and being detached, it is a chrysalis; and the third, a butterfly. It should seem that the ancients were so struck with the transformations of the butterfly, and its revival from a seeming temporary death, as to have considered it an emblem of the soul, the Greek word psyche signifying both the soul and a butterfly. This is also confirmed by their allegorical sculptures, in which the butterfly occurs as an emblem of immortality." Swammerdam, speaking of the metamorphosis of insects, uses these strong words: "This process is formed in so remarkable a manner in butterflies, that we see therein the resurrection painted before our eyes, and exemplified so as to be examined by our hands." "There is no one," says Paley, "who does not possess some particular train of thought, to which the mind naturally directs itself, when left entirely to its own operations. It is certain too, that the choice of this train of thinking may be directed to different ends, and may appear to be more or less judiciously fixed, but in a moral view, if one train of thinking be more desirable than another, it is that which regards phenomena of nature with a constant reference to a supreme intelligent Author. The works of nature want only to be contemplated. In every portion of them which we can decry, we find attention bestowed upon the minuter objects. Every organized natural body, in the provisions which it contains for its sustentation and propagation, testifies a care, on the part of the Creator, expressly directed to these purposes. We are on all sides surrounded by bodies wonderfully curious, and no less wonderfully diversified." Trifling, therefore, and, perhaps, contemptible, as to the unthinking may seem the study of a butterfly, yet, when we consider the art and mechanism displayed in so minute a structure, the fluids circulating in vessels so small as almost to escape the sight, the beauty of the wings and covering, and the manner in which each part is adapted for its peculiar functions, we cannot but be struck with wonder and admiration, and must feel convinced that the maker of all has bestowed equal skill in every class of animated beings; and also allow with Paley, that "the production of beauty was as much in the Creator's mind in painting a butterfly, as in giving symmetry to the human form."
