Travellers state that there is on the island of St. Luce a cavern, in which is a large basin twelve or fifteen feet deep, at the bottom of which are rocks. From these rocks proceed certain substances that present at first, sight beautiful flowers, but on the approach of a hand or instrument, retire like a snail, out of sight! On examination, there appears in the middle of a disk, filaments resembling spiders' legs, which moved briskly round a kind of petal. The filaments, or legs, have pincers to seize their prey, when the petals close, so that it cannot escape. Under this flower is the body of an animal, and it is probable he lives on the marine insects thrown by the sea into his basin. * * * * * The first clock that ever measured time was made for the Caliph of Bagdad. This art was afterwards lost for several centuries. =Skate Runners.= At Drontheim, in Norway, they have a regiment of soldiers, called Skate Runners. They wear leg gaiters for travelling in deep snow, and green uniform. They carry a short sword, a rifle fastened by a broad strap passing over the shoulder, and a climbing staff seven feet long, with a spike in the end. They move so fast in the snow that no cavalry can overtake them, and it does little good to fire cannon balls at them, as they go two or three hundred feet apart. They are very useful soldiers in following an enemy on a march. They go over marshes, rivers and lakes at a great rate. =A Receipt to make Peach Wine.= Take four or five bushels of ripe juicy peaches, mash or bruise them in a tub, and pour them into a barrel, large enough to contain them, and place it in a cool place. At the bottom of the barrel, before putting in the peaches, some clean straw must be placed to prevent the pumice from filling up the spigot. The head of the barrel must be covered. In about three days the Peach Wine is ready for use. Draw it off, from the spigot, and if care and attention have been adopted, a delicious beverage will be produced. =A Novel Enterprise.= An expedition, which promises the most important results both to science and commerce is at this moment fitting out in England, for the purpose of navigating some of the more important unexplored rivers in South America It is to be under the command of Lord Ranelagh. Several noblemen and gentlemen have already volunteered to accompany his lordship, and the enterprising and scientific band, it is said, will sail as soon as the necessary arrangements shall be completed.
