The chief points for effecting the desired object con-! persons may find nutriment if planted with potatoes as

sist—I1, in increasing the functional powers of the bers; 2, in restricting the metamorphosis of the eaves. We effect both these points in the following rnanner:—Durine the 5th, 6th, and 7th week after the cubers had been planted, or inthe 4th or 5th week after ine planting of rooted shoots, or at any time when the young plants have reached a height of 6 to 9 inches above the ground, the tops of the branches are lopped or clipped by means of the thumb and first finger to the extent of halfan inch.* This operation must be re- peated the LOth or Eth week after planting, it being nomaterial at what hour of the day. This process pro- duces acheck to the development of the stem and branches, the consequence of which is an increased eitort of the nutritrve and assimilating substances, not only upon the functional powers of the tubers, but like- wise upon the branches ofthe aerial stems, which not only benefits the functional powers of the root, but strengthens hkewise its leaves and branches so mate- nally that thenutritive substances increased through the physiological activity of these parts are now em- ployed for the improvement of the tubers ; besides which, the more vigerous branches and leaves prevent the di- rect imfluence of the sin upon the soil and the injurious edeot of desiccation. By checking the metamorphosis of the: leaves, ‘their transmutation into calyx, corolla, organs of fructification, and petioles, is prevented, which parts are produced at the expense of the nutritious sub- stances reserved in the plant ; hence by preventing the metamorphosis of leaves, these substances benefit the development of the tubers. Actuated by such consi- derations, | tried the experiment in 1846, of clipping the extreme points of the branches of some potato plants which { marked for the sake of distinction. ‘They dis- tinguished themselves in their growth soe strikinzly by a stronger ramification, larger and darker leaves, from the other plants, that it did not require any marking on may part to recognise them again. The produce of tubers was abundant, and they were quite sound, while che other plants in the neighbourhood upon which IT had not tried the experiment, produced without exception not enly a much smaller quantity, but the surface of the tubers was likewise uneven, and suffering in numerous instances from the prevailing epidemic. ‘I'hongh I con. sider this experiment imperfect, and not guite certain in its results, it gave me, nevertheless, encouragement to renewit. I repeated the experiment in April, 1847. upon a low situated piece of land, with the white round potato usually cultivated here, and which suffered only sightly at the period that the disease showed itself for che first time in 1845. They were planted by a farm servant well acquainted with the method of planting. After they had been weeded, towards the end of M ay, ( tried again my experiment by clipping the tops of the piants of every alternate row which process was re- veated towards the ead of June. The success sur- passed all my expectations. The stems of the plants; which had not been clipped were slender, weak, and possessed only afew leaves. Ona neighbouring piece of land tubers of the same quality had been planted on the same day as mine, the herbage of which was Jeft to vature. It looked healthy, even luxuriant, during the

Remeapy ror tHe Porato Disease.—A paper ap- ‘pears in the ‘Agricultural Bulletin, from which we learn that a chemist, nained Eusobius Griss, had been paying great attention to the disease, and has found a di- rect and radical remedy. This gentleman, guided by analogy, has compared the disease of the vegetable to the chlorosis which attacks the human frame; and the idea suggested itself to him whether to apply the same remedies which improve the vitality of the blood, which restore its energy and its colour, might be advantage- ously restored to in re-animating the languishing vitality and tone ofthe discoloured leaves. He accordingly had recourse to an application of salts and iron. He watered the plants with a solution of sulphate of iron, containing from 10 to 20 grains to a litre of water, and moistened the leaves with a lighter solution, containing only about three grains to a litre of water. This last method proved much more immediately the efficacy of the remedy than when it is done watering the plants; for in the latter case it might be attributed to a chemi- cal re-action produced in the interior of the soil. A committee was oppointed by the Royal Society to test the result of Mr. Griss’s remedy. Experiments were made in various parts, some on an extended, some on a

THE WHEAT FLY.

As the Wheat crop on this Island is said to be con- siderably damaged by the ravages of a grub, miscalled the ‘Weevil’ the following description of the real cause of the mischief may prove interesting to our read- ers. We publish it at the request of the Committee of ihe Royal Agricultural Society. It is-taken from an ssay on the Wheat Fly, by Asa Fitch, M. D., Salem, New York, published in the American Quarterly Jour- nal of Agriculture and Science. Under the name of the Wheat Fly the author includes the Cecydomyia tritici, previously discovered by the Naturalist Kirby, and an- other species differing from the above in its spoted wings, and first noticed by himself. Belonging to the same genus and alike in habits and in transformations,

they may both be conveniently described under the same common name.

color, and are hatched in about a week after they are deposited. r

‘From this egg proceeds the larva, which is & minute oblong, soft worm, without feet or hairs, whitish at fre but soon changing to a bright amber or orange yellow color. It moves but slowly, by a wriggling motion of its body. When full grown, this worm is less than the tenth ef an inch long, of a rich orange color, and ova! shape. Having reached this state about the time that the grain is ready to be cut, it waits a warm rain of heavy dew, when it descends, most probably by night, by gliding down the moistened stock and enters the ground. Here it remains during autumn and winter preparing for its transformation into a winged insect’ when the general heat of spring shall arouse it to a new existence. Facts show that when the grain is cut before the descent of the larva or maggot, great quantities of them are often carried into the threshing-floor, and may be found among the screenings of the wheat. These being kindly emptied out by the farmer into his barn. yard, have a secure asyluar provided for them until the coming season.

‘ITS NATURAL ENEMIES.

‘It appears that the most effective destroyer of this insect, is the common yellow-bird. (Fringilla trislis, Lin.) This beautiful little bird isin the habit of fre. quenting grain-fields when the fly is at work, and wood. ker-like extracts the nascent larva from the ears of the wheat. Alighting, it adroitly grasps the wheat stalk just below the ear, and clinging earlessly to it, even when swayed to and fro by the wind, with its bill, it down the chaff from the grain, and rapidly picks offthe worms. Ignorant persons suppose that its object is the kernel of the wheat, not knowing that in common with all our small birds it is the natural friend and ally of the farmer. Sowing the field with lime, at the time when the wheat is in blossom, has been much urged as a remedy against this fly, but facts show that it is not to be depended upon. ‘Early sowing in the fal) so that the wheat will be too far advanced in the spring to be penetrated by the fly, appears the most ready and practicable means of avoid- ing its destructive effects. In many cases, it is un- doubtedly efficacions, but the observations of the writer tend to show that the swarming of the fly coversa space of six weeks or more, during soine part of which, the grain must necessarily be in the proper state for the deposition of its eggs.

‘He recommends that the screenings of the fanning- mill be closely examined, and ifthe minute yellow wheat worms are numerous in them, the farmer shou!d consider ita sacred duty which he owes to himself and his neighbors, to consign these screenings at once to the flames. Ifthere are but occasional worms among them, let them be emptied into the hog-trough, but never empty then upon the ground, or among the straw of the barn-yard, unless they appear to be entirely free from
