Fifty specimens of a good flowering plant, when put together, will give more effect when in bloom than fifty varieties of the best flowering plants in the world; and one kind of annual will have more effect in a planted " bedding" flower-bed than two, three, or more kinds. A rose-bed, consisting entirely of one variety - say Souvenir de Malmaison - is more effective than a heterogeneous mixture. - All the China Asters, now so beautiful and improved, will come in a month earlier, if sown in the autumn. Another sowing of them in the open border by the end of April, and a third in May, will save all the bother of raising them in hotbeds. Clarkias, Collinsia bicolor, Gilia tricolor, and the spotted Nemophilas, should be twice transplanted; the sweet Alyssum is also best from an autumn sowing; Oxalis Boweii, when treated as a window plant, will bloom best in the late summer and autumn months. As soon as the flowering is over, lessen water, but give a little so long as the leaves are green. In potting afresh, place from eight to twelve strong bulbs, about three inches or so from the surface, in a six or eight-inch pot. Passiflora carulea is hardy at Philadelphia, and should be planted for balconies in fibry loam and sandy peat.

Once established, it should be pruned close back to within a bud or two of the main stems every winter, - Sir Joseph Paxton, of Crystal Palace celebrity, commenced life as a gardener; and the best mathematician at King's College, Aberdeen, at this time, is a man who part of the year works in agriculture, and during the other part studies in college. Seek, then, to inscribe your name in that golden record of self-made men, a place in which none of us can inherit, but all may aspire to attain. First of all, you must have self-reliance, dependence on your own powers, to achieve your own independence. The next step is industry; "the diligent hand maketh rich": - " Bound swings the hammer of industry, Quickly the sharp chisel rings, And the heart of the toiler has throbbings That stir not the bosom of kings.

"He the true ruler and conqueror, He the true king of his race, Who nerveth his arm for life's combat, And looks the strong world in the face".

John Wesley, in his sermon on the use of money, says: "Make all you can - save all you can - give all you can. You must also have temperance. Intemperance, like improvidence, is one of the evil eyes which look upon the labor of this country, and is not only the father of that cruel wolf which seeks admittance to the poor man's hearth, vis., want, but is the destroyer of a man's own self-respect, comfort, and respectability. You must likewise possess integrity of heart both towards God and man; be just and true in all your dealings, and commend yourselves by probity of conduct alike to all around you, as to Him (who seeth not as man seeth). The last step of the ladder which, by the divine blessing, you may hope to attain, is independence." - The microscope is now so much unproved as to attract attention from those least given to observation. When we see a soft snail eating a hard cabbage-leaf or carrot, if we reflect on the operation, we must conclude that it cannot be performed without the agency of teeth. The microscope shows us in the palate of a land or water snail, rows upon rows of teeth, containing, altogether, hundreds and hundreds of molars.

The shark's rows of teeth are nothing to the weapons that line the mouth of the little shell-fish called a whelk - half a dozen in each tow in the middle, with a chevoux de frize of tusks on either side. 'A French microscopist made quite a sensation, lately, by proving that the male itch-insect, which had been unknown before, was neaver found in the furrowof the skin as the female always is. He lives on the surface of the epidermis, and being smaller, had escaped observation. - A bunch of the variety el Banana, called the St. Helena, was raised in England (under glass, of course) in 1843, weighing one hundred and thirty-three pounds. The proper minimum temperature for the Banana, is from 60° to 65° in winter, in summer from 65º to 70°, and the maximum 75º to 85º, giving air on favorable occasions, keeping up. a moist, atmosphere, and using liquid manure occasionally. - Ammoniacal gas-water poured into, the runs and haunts of ants, is a certain destroyer. - A mushroom will lift a heavy stone by its force of growth; considering that it is of a weak structure, and with a shallow root, it is a puzzling question haw it does this. - If by any chance you happen to have a bad plant, destroy it; do not give it away.

A taste for flowers is likely to prevent a taste for sinful pleasures; we ought therefore to give away freely of the best we can spare. Were the flowers of the world to he taken away, they would leave a blank in the creation. Imagination cannot suggest a substitute for them. Be grateful for the gift of flowers. - The English railroads maintain an army of 100,000 employees, officers included: four tons of coal, and twenty tons of water, are flashed into steam every minute throughout the yearl Twenty-six millions of "sleepers" were employed on the original construction of the English roads; they disappear at the rate of two millions a year. To provide these alone, requires the felling of 300,000 trees annually; 5,000 acres at forest must be yearly cleared to provide the necessary quantity. If these figures were tried for America, they would be more than doubled. - some time since, a correspondent of the Boston Cultivator recommended potash for the rats, which troubled him very much, so that he felt justified in resorting to extreme measures to effect their expulsion from his premises. He pounded up potash, and strewed it around their holes, and rubbed some under the board and on the sides where they came through.

The next night he heard a squealing among them, which he supposed was from the caustic nature of the potash that got among their hair, or on their bare foot. They disappeared, and for a long time he was exempt from any further annoyance. Answers to CORRESPONDENTS. - (Omega). Lettuces and radishes do net come hard except on wretchedly poor land, or on very ill-cultivated ground. Ridge up a border for them this winter, and put three inches of quite rotten dung all over it. After the ftrst frost, dig it deep, and mix the dung well among the soil. When the surface is very dry in March, put two inches of rotten ten, or a good sprinkling of salt, all over it, stir the surface, and sow.
