A gentleman in Connecticut has succeeded in artificially breeding trout in his cellar, through which he has turned a stream of water. - A few years ago, it was difficult to procure salmon in Paris for less than from two to four shillings (English money) per pound. Now, in consequence of their fast increase through artificial breeding, they have been sold as low, this season, as sixpence per pound. Is there any reason why the people of this country should not "go and do likewise?" - Dr. Carl Muller has commenced a continuation of the Annales Botanices Systematica of Walpers, of which Vet. IV., Part 1, is before us, extending from Ranunculaces) to Nymphaeaces. - - In Xenophon's minor works, will be found some excellent remarks on planting, horticulture, etc., that may still be studied with advantage. In one of his treatises, occurs the following; "'Would you merely heap up the earth around the plant, or tread it down hard!' 'I would tread it down/ said I, 'assuredly; for if it were not trodden down, I am well aware that the untrodden earth, if wetted by rain, would be turned into mud, and, if soorohed by the sun, would become dry to the very bottom; so that there would be danger lest the roots of the plant, under a pro-valence of wet weather, should be rotted by damp, or should be scorched up in hot weather from the roots being heated through the dryness or porousness of the earth.'" - The lea-son to be learned from diseases which are dependent upon parasites, whether animal or vegetable, is most important.

It is simply that, in our treatment of the maladies of vegetables as well as those which affect our own frame, we should not trust to chance or mere empiricism, but, as a first step, we should study as intimately as possible the nature and habits of the organisms which produce the disease. And to this end, science must be the helpmate of practice, to enable the cultivator to observe and distinguish accurately. A knowledge of the cause of disease is a step more than halfway towards its cure, and thus the student in the obscurest branches of science, against which utilitarian objections may most readily be urged, may prove a real benefactor to his fellew-men. - Calvert Vaux, in his book on Villas and Cottages, remarks truly, that "the constant recurrence of about the same requirements will, of course, lead to much similarity of plan, particularly in small buildings; but the monotony that this would occasion, may be agreeably relieved by variety in color, both in the interior and exterior. Different patterns of paper will make two rooms of the same proportions no longer look alike, and the same result will be obtained on the exterior, by adopting different tints for the walls and the wood-work." - The use of a philosophical discovery is often slow to get some of its most useful applications.

The invention of a double-walled pitcher, is an instance: Ice put into a pitcher of this kind with water, remains ice all the hottest day, to the great convenience of the family. We made double walls for ice-houses, and then brought the ice up, for fifty years, to be melted in an hour. Every one who has used the new ice-pitcher, will commend it to his neighbors. - We are pleased to see that a marl Company has been formed for distributing the green-sand marl of New Jersey. The Company sell it at seven cents the bushel, which, when dry, weighs eighty pounds, and is said to contain five per cent, of potash, or nearly as much as there is in a bushel of unleached wood ashes. There can be no doubt that it contains much that is necessary to our commonly cultivated plants. Charles Sears, Riceville, N. J., is President of the Company, and T. Townsend, 82 Nassau Street, N. Y., Treasurer. Having witnessed the beneficial effects of marl on grass lands many years since, we are prepared to believe the use of it in gardens and greenhouses may be highly important. - Our readers must have been struck with the name of the Director of the "Acclimation Society" at Algeria, mentioned in our last " Gossip." They are ascertaining which plants can be accli.

Gossip #1

A grape grower in France has succeeded in destroying the oidium by burning sulphur under his trellis once a week, and thus obtained a noble crep of grapes, while those around him had very few. One difficulty encountered in the application of any remedy in the wine countries, arises from the sluggish habits of the peasants, and another from religious scruples, as if any exertions of their own out of the ordinary course, interfered with the dispensations of Providence. - M. Bourgeois presented to the Imperial and Central Society Of Agriculture some shoots of a vine, as the result of numerous experiments which he had made with respect to ringing, and which he stated had been completely successful as regards the improvement of the grapes, the berries of which became larger, and ripened earlier in consequence of the operation. According to him, this experiment is of great importance, especially in odd, moist, and late situations in the neighborhood of Paris, where, last year, the grapes did not ripen well* He also states that it prevents the berries from dropping off.

Borne members of the Society thought that the operation would have no effect upon the grapes situated below the incision, and others believed that ringing weakens the plant. - The wild carrot makes good pegs for verbenas and petunias. - In the Champa Sly sees, this season, there are some trees which present an odd appearance. They are good sized young horsechestnuts, which were planted this spring, when in leaf. They are alive, but seem not yet to have a hold on the soil enough to supply the exhaustion of evaporation. Accordingly, the trunks are bound round with canvas inclosing a quantity of moss. At the top of this, the stem is surrounded by a funnel-shaped piece of zine, doubtless to facilitate the moistening of the moss. - A very good result would be produced, if the crest or crown of the white thorn could be grafted with the crimson; the force of contrast would be surprising and effective; or the white on the crimson would be equally beautiful. This may be readily carried into effect on the lawns or pleasure-grounds, where the trees would ( be safe, which they would scarcely be in mors exposed situations. - A second edition of Mr. Baker's Rifle and Sound in Ceylon (with woodcuts), has Just appealed.

Those who hare read the author's very interesting Eight Years' Wanderings in Ceylon, will gladly make acquaintance with the little London volume; those who now read the latter, will be anxious to see the former. The Rifle and Hound is a sportsman's book, full of hunting adventures, advice about guns, and stalking, and camping out; and of the way to make hunters war upon elephants, deer, bulls, boars, and bears. - Some of the reeds of Brazil, called Taqua-russa, are living fountains; they grow from forty to fifty feet high, with a diameter of six inches, form thorny, impenetrable thickets, and are exceedingly grateful to hunters; for, on cutting off such a reed below a joint, the stem of the younger shoots is found to be full of a cool liquid, which quenches the most burning thirst. - The floor-matting so much employed in America, is made from a reed (Papyrus corymbosus). Another reed helps much to protect the banks of the Ganges from the rapidity of the stream, and the force of the tides; it is the Cyperus inundatus, and should be tried on our Western rivers - as, in Holland, the Carez arenaria is carefully planted on the dikes, where its far extending roots, by mutually interlacing with each other, fix the sand, and give strength to the embankment.

The Cyperus hydra (called Nut-Grass in the West Indies) is a pest, overrunning sugar plantations, and rendering them barren. - -The latest adaptation of India-rubber, is to inclose a strip in wood in the form of a great lead-pencil, when it makes a most convenient article to rub out lead marks on paper. It is sold in this form, very generally, by stationers.

In its wild state, the pine-apple, when unripe, is so excessively acid as to burn the gums of the mouth; it is then employed, in the West Indies, to destroy intestinal worms. - The tuberose emits its scent most strongly after sunset, and has been observed, on a sultry evening, after thunder, when the atmosphere was highly charged with electric fluid, to dart small sparks, or scintillations of lucid flame, in great abundance, from such of its flowers as were fading. - A good gardener asserts that he has found "well kept" was synonymous with "easy kept," and that, with plants as with other things," a stitch in time saves nine." - The Pistol plant is thus alluded to in the Sydney Morning Herald: "A hothouse plant, Pilea allitrichoides, of tender, brittle, and juicy aspect, looking as if good to eat in a cooling salad, is really of so explosive a temperament that it might fairly be called the Pistol plant. When near flowering, and with its buds ready to open, if the plant is either dipped in water or abundantly watered, each bud will explode successively, keeping up a mimic Sebastopol bombardment, sending forth a puff of smoke, or of dusty pollen, as its stamens suddenly start forth to take their place and form a cross.

It is an amusing toy." - The Squills (Scilla)) make excellent edgings of bulbs, and are too little known among us. - -Cherries of good kinds were readily retailed, the past season, at ten and twelve cents the pound.
