The foreign papers say that Messrs. Sehroeder and Dnsch make it apparent that meat may be kept fresh for a long time in filtered air. The filtration is effected by very simple means, namely: panels of cotton wadding to the safe or closet in which the meat is hnng. Butchers' meat has risen to so extremely high a price in Paris, that there has been some talk of the Imperial Government undertaking to sell preserved fresh meat at a reasonable rate. - A new yam, as it is called, has been sent from Mexico to the Academie at Faris. It is of prodigious size (two metres fifty-one centimetres long, eighty-nine centimetres circumference), and weighs eighty-six kilogrammes. Some of the academicians say it is rather a rhizome than a root; not a yam, but a hitherto undetermined vegetable (perhaps a dioscorea) - a question to be settled by botanists. In Mexioo, as we are informed, it is not at all uncommon for the roots to grow to a length of four metres. They are a palatable article of food, notwithstanding their size. - Macbrlde's flax scutching machine cleans more than five hundred pounds of fibre in ten hours, and when driven to the utmost, will turn out nine hundred pounds in the same space of time.

Compared with hand-labor, there is a gain of more than half in favor of the machine - at least, so say the initiated.

Mr. R. Brringtou, a name well known to gardeners, says, in a late article on peach pruning, " there is no occasion for much fuss about it. Trees have been repeatedly seen bearing better crops, badly pruned, than those which had received the most scientific knifing. This, however, does not prove that pruning is quite immaterial, but that it is not the 'keystone' of the arch. Young peach-trees, as soon as they have grown one year from the bud, are termed ' maidens.' They have one straight shoot, with generally a few side-spray. Below this latter are generally four or five dominant side-buds which have never sprouted, and the pruning knife is generally entered immediately above these. In the second year, the tree sprouts from three to five shoots, according to its power, and these are pruned back in the rest season for a double reason - to remove ill-ripened portions, and to cause the tree to branch more, in order to cover the wall. Henceforth, the thing gradually assumes the character of a fruit question rather than one about wood, and the business is, that whilst every regard is paid to the bearing wood, attention is also given to a proper succession of wood shoots." - A letter writer, addressing the U. S. Patent Office, from Kerr County, Texas, expresses surprise that that department has not noticed the pecan-nut, which grows abundantly in Texas. About 200,000 bushels of the nut have been exported from that State to Europe and elsewhere, producing $400,000. One tree will often produce from fifteen to twenty bushels, worth from $30 to $40. - A pretty philosophical toy is exhibited in Philadelphia. It is a toy balloon, and is a Paris invention, made of India-rubber, filled with common burning gas.

The levity of the gas carries it up to the top of the window where it is exhibited, when it rebounds and descends again, keeping up this motion continually. The invention is better than a kite, for it depends upon no current of air to make it asoend and it can be fastened by a string to a child's hand, or the button-hole of his Jacket, and be made to follow all his movements. - The California Agricultural Society speaks of a remarkable case of success in the product of the bee: Mr. Briggs, of San Jose, brought out with him, the last year, from the States, a large swarm of bees; from this one swarm, eight $warm$ were hived the first season. There is no parallel case to such a product on record, and the same prolific character is manifest in all natural history there as well as in the products of farm, grain field, and orchard. - The Committee who report to the Society, went to see a Spanish Don, and there they found the following matter of interest to relate: "A two year old grizzly bear, having been caught in the barley-field the night previous to our arrival, the natives belonging to the establishment amused themselves, just after we came up, by tying the fore-leg of a bullock to the hind-leg of the bear.

After sundry toss-Ings and huggings, while we were faring sumptuously at the table of the Don, his bearship, we were informed, took Just cue horn too much, and died from the efect of an extemporary bowel complaint." - The application of gas to cooking has been made with success in this country, and for heating small greenhouses, it is believed to be valuable. In England, neat library tables are made with hot-water pipes beneath, which add greatly to the comfort of a loom; they may be heated from the kitchen fire. - A border of high or standard roses is improved by planting among the stems mahonias; the bareness of the border and lower parts of the stems, is thus taken off, as it is thus effectually filled up with foliage. - -The Emperor fountain at Chatsworth is of such force, that it is calculated the water escapes at the rate of a hundred miles per minute, rising to the height of two hundred and sixty-seven feet. - During inclement spring weather, many stocks of bees in common hives require feeding more abundantly than can be accomplished by pipes of elder and other primitive contrivances.

A good plan to feed stocks in the common bell-shaped hives, is to cut a small hole in the top, drive three flat-headed nails around it, standing up half an inch; on these lay a piece of empty comb, the upper cells of which can be filled with syrup, and the whole covered closely with an empty hive. The bees will readily take down a pound of syrup a day. When not required, a cork secures the hole.- - - The rose Isabella Gray, from this country, has become a great favorite abroad. It is tea scented, and they say of it, "a real yellow rose at last." - At a late London exhibition, a gardener exhibited a fruiting branch of the Royal George Peach, from a tree fifty years old. At the same table were two glased plates of singularly beautiful anatomized leaves, prepared and painted on by Lady Dorothy Nevil. This is a new process, by which the web between the veins is not destroyed, but looks as if the leaves were first divested of the outer skin or covering, and the rest bleached white like a piece of bladder, with the mid-ribs and all the veins as distinct as if the web was destroyed.
