A very fine new radish has been introduced into France from China. It swells at the bottom, where its diameter is about two inches; it is from three and a half to four and a half inches in length, and of a clear carmine color.-----A most remarkable fact has been discovered by naturalists in Madeira, of the frequently wingless condition of the beetles; out of 550 coleoptera there collected, 200 are more or less without wings. As in the caverns of North America and Styria, the beetles, etc, which inhabit these eternally dark recesses, are eyeless, inasmuch as sight would be useless to them, so on the small island of Madeira the beetles are wingless, because powers of flight would be of little use or injurious to them, as when once on the wing they would be liable to be blown out to sea and lost;-----The number of sheep in the British islands is estimated at 85,000,000, worth two hundred and fifty millions of dollars! producing 157,000,000 pounds of wool, worth fifty millions of dollars anually; this is independent of 60,000,000 pounds imported each year. - The last remedy for the curoulio is to smoke the trees with tobacco on the first appearance of the enemy. Smoke them well night and morning, for one week.

Very probably the best remedy proposed. - -We found Mr. Hovey, of Boston, in possession of a number of new varieties of the strawberry, and among them the "Sir Harry," which, we were not aware had been received in this country. He has also "Admiral Dundas," of which it is said 18 weigh a pound. "Sir Charles Napier" is also a much esteemed variety. When we come to the description of places around Boston, we shall notice several of Mr. Hovey's novelties.-----They had a discussion respecting the strawberry at the Fruit Growers1

Convention of Western New York, which is well reported in Moore's Rural New Yorker of July 26th. The cherry also claimed a large share of attention.-----The Quercus gramuntia produces edible acorns quite equal to chestnuts. These were much eaten by the ancients, and were believed by them to fatten the tunny-fish on their passage from the ocean to the Mediterranean, and are the bellotas which Teresa, the wife of Sancho Pansa, gathered in La Mancha, where they still grow in the greatest perfection, and sent to the duchess. - - Spain has at last attempted a reform in her agriculture, and in place of her old bull-fights has had a cattle show, which is to be triennial. A prise was awarded to an English Durham bull. With great capabilities, Spain remains in the rear in the march of improvement, though symptoms of her awakening are becoming apparent in railroads and manufactories, and at last the cattle show for the bull-fight.-----Lime-water poured freely on the nests and barrows of ants will cause them to flit, if it does not kill them.

Arsenic in a solution of sugar and water is a certain remedy, but care must be taken that it is not accessible to other living things; therefore, cover the saucer with a slate and a stone, leaving a couple of pegs between the slate and saucer to let the ants in freely. By using honey and water you may trap them by myriads as the honey holds their feet like birdlime.-----A new white grape, a seedling of the Black Hamburgh, is spoken of favorably. It was raised by Mr. Carpenter, near Birmingham, is a distinct grape, much flattened at the eye, and of a dear amber color and rich flavor. Mr. Beaton thinks the pollen of the sweet water grape produced this seedling, and that it is well worth growing. Not yet named.

The hollyhock continues to grow in favor abroad. Instead of the tall single flowered varieties, we have them now with close spikes of beautifully formed, compact, double flowers, With clear colors ranging from fine white to nearly black, and lasting, as all double flowers do, much, longer than single ones. They seem to be favorites in Boston.- - A plant may lose hall its weight by drying, and yet be restored by care. Be Candolle has recorded an instance of a Semvervivum ccupitotum, which had been placed in a herbarium for eighteen months, and from which he afterwards detached a living bud and reared a plant. But the tenacity of vegetable life is best exhibited in the property which seeds possess of retaining their powers of germination, after having been exposed to very considerable degrees of heat and cold. Some, also, which have partially germinated, may be again dried and kept for-months, without losing the power of germinating afresh, although they are sensibly weakened by such treatment. The revival of plants among the cryptogamio tribes, after a very long suspension of the vital functions, is well authenticated. - - Trees are the indispensable objects in scenery; indeed, they are the essence of a true landscape.

Scenery unadorned by trees is like a beautiful bird stripped of its plumage; creation is there, but it is without its usual charms.
