ACTION OF ROOTS ON GLASS.—Dr. JACKSON stated that he had noticed the fact that glasses in which hyacinth bulbs had been brown, were corroded. He had also noticed the same effects on bottle glass that had lain in garden mould. He supposed that the plants had the power of decomposing glass as well as the feldspar of granite, and of appropriating to their use the potash contained in the ashes of plants.— Proceeding of Boston Society.
GLANDERS IN MAN AND IN THE HORSE.—Glanders and farcy are essentially contagious diseases. Whether developed in man or in the quadrumina. There are, moreover, decidedly infectious as well as contagious in the latter class of animals,—that is, the contagious principle may be transmitted through the medium of the atmosphere, as well as by actual contact, from one animal to another. I have known several instances in which there was no possibility of contact with glanderous matter, and yet the disease was developed in healthy horses. A gentleman of fortune in the west of Ireland had had his stud infected with glanders. Every particle of wood work in the stables, including stalls, rack, manger, &c. was taken down and replaced with new materials. The plastering on the walls was completely removed, and the pavement ripped up, and all was replaced with entirely new work; but the first horses that were again put into those stables became infected, and they were ultimately razed to the ground. It would even appear that the contagious principle remains for a long period, sometimes for years, in any stable or shed where glanders or farcy may happen to have been developed.

EFFECTS OF GAS-TAR ON STEMS OF GRUIT TREES.—Some time since one of our subscribers recommended the use of gas or coal tar fro dressing the stems of fruit trees; I beg to state that a more injurious ingredient could not be used. About twelve years ago the person who had the orchard I now possess, being afraid that sheep and pigs would injure the bark of the trees, had them dressed about three o four feet up from the ground with gas-tar, which answered in every respect the intention—to preserve them from cattle; but they suffered in a way equally bad. The apple trees, from the effects of the gas-tar, gradually began to fail, and some died altogether in about five years after the application. The bark of others close to the ground became rotten and even up to this time, its deleterious effects on the trees are perceptible. Its application to plumb and pear trees caused the stem to overgrow immediately above where the tar had been put on; several of these threes became loose in the ground and did not thrive for a long time afterwards. The gas-tar might, however, be tried in a diluted state, for the sake of experiment, and then only on trees that are cankered and of little consequence, in the portation of one part gas-tar to three of train oil, well mixed together, with the addition of fifteen parts of cow dung to two of water. If the stems of trees were covered with this, no cattle of any kind would touch them, and the diluted tar might act in some respects as a manure.
HORSES.—The best way of preventing horses pulling the hay out of the rack, and wasting it under their feet, is to cut it with a chaff-cutter; the trouble will be more than compensated by the quantity of hay which will be saved; but possibly the hay is bad, or mixed with some weeds which the horses do not relish; in that case if it be given in a hay-trough, and not a rack, they will eat all that is good, and leave the bade.—Horses are, in general, fond of and thrive on Swedish turnips; they should be sliced and given raw; some, indeed, prefer steaming or boiling them, but we question much if the food is thereby improved. Carrots are preferable for horses, and nearly as heavy a crop of them may be grown as of Swedes; no farmer should be without them.
TO CURE WOUNDS IN CATTLE.—When the animal receives the wound (if of an extensive nature, to be closed with a few stitches, not too closely put into the lips of it) a loose bandage is to be wound round it (not for the purpose of ligature, but to retain a constant moisture), which must be kept unceasingly wet by and application of cold clean spring water, till the wound is quite well. This treatment is also equally efficacious for fracture; the parts must be bound together (not too tightly) with splints; the beast must not be allowed to move; and should proud flesh appear when a wound in healing, as often happens, a piece of blue stone should be rubbed on the part so affected for a few days, which will remove the excrescence. — Farmer's Gazette.
ON THE SHED FEEDING OF SHEEP.—The following result of the plan of shed feeding of sheep, which we copy from the English agricultural Society's Journal, will prove interesting to our agricultural readers.—Mr. CHILDERS selected two lost, twenty in each, of Leicester whether hogs, as similar in quantity, as possible. One lot was place under shelter in a yard, and the other was folded in a field. They received the same kind of food, viz., cut turnips, ad libitum, half a pound of linseed cake, half a pint of barley per sheep per day, a little hay, and a constant supply of salt. At first they consumed nearly the same quantities of food, eating each day about 19 lbs. of turnips per sheep; but, after the third week, there was a falling off in the consumption of the hogs in the shed of 3 stone of turnips a day, i.e., 2 lhs. A piece; and in the ninth week there was a falling off of 2 stone more. Of linseed cake there was also a falling off of 3 lbs. a day, i.e., nearly one third of the quantity given. The hogs in the field consumed the same quantity of food from first to last. The result of the experiment was that the sheep in the shed, though they consumed nearly on fifth less food, made above one third greater progress." The following is the result of another trial with three lots of sheep:—one lot was entirely covered, another placed under a shed in the yard, and the third entirely exposed, all of them having one pint of oats per sheep per diem. The first consumed, on an average, between Nov. 18, 1842, and March 9, 1843, 9 lbs. of cut turnips and other roots per diem and increased in live weight during that time 23 ½ lbs. per sheep; the second consumed 11 lbs. of the same food, and increased 25 lbs. in weight; the third consumed 17 lbs. of cut turnips, &c. a piece each day, and increased in live weight 23 lbs. during the period. The several lots, it thus appears, did not differ so much in their growth as in the case reported by Mr. CHILDERS, but there was a much greater difference in the quantity of food eaten by them: so great a difference, indeed, that were this result to be generally expected from a similar treatment, twice as many sheep might be kept in a fattening condition on the same quantity of food under perfect shelter, as under entire exposure.
