M. Millon, an Algerian colonist, according to a report by M. Payen to the Central Agricultural Society Of France, has round in the thornless species of Cactus a valuable food for cattle in Algeria, because it supplies the want of green fodder during the season which, from the month of June forwards, burns and destroys every sort of herbaceous vegetation which cannot be continually watered or irrigated. - An application of sulphur is thus described in the Gardeners' Chronicle: "I had before applied sulphur in various ways, and this year I only mixed up such a quantity in water as would freely pass through a Read's hand syringe, and dashed it freely on the glass above the vines. The sulphur adhered to the glass and dried on, but, in windy weather, is partially detached ill fine powder, and falling on the leaves, keeps them under the continued influence of its effects; and certainly a cleaner and more healthy foliage cannot be desired. I may mention that a Black Hamburg recently introduced, began early to show symptoms of mildew, but entirely recovered, and has not since been unhealthy." - The Wistaria vines are the best runners to cover unsightly trees that are needed to remain in your grounds from any cause. - Many classes of herbaceous plants continue to brave the rigors of the winter, covered with a ootid and bright mantle of snow; of these spocies which survive the winter, some are biennial, and others perennial; and, with respect to the former species, though their life may be prolonged by transplanting them, and thus retarding the period of their flowering and bearing seed, yet no artificial means can prevent their decay, after they have provided for the future propagation of their species, by exercising this important function: -

"He marks the bounds which winter may not pass, And blunts his pointed fnry; In Its ease, Basset and rude, folds up the tender germ . Uninjured, with inimitable art;

And, ere one flowery season fades and dies, Designs the blooming wonders of the next"

Certain fungi are believed to be connected with the process of fermentation. The curious circumstance that, in certain bake-houses, all the bread becomes ropy, and though sometimes prevented from assuming this condition by repeated washings of the walls and floor with chloride of lime, the evil is occasionally so obstinate as to prove the ruin of the establishment, is probably dependent on this cause. Dutrochet believes that he witnessed the growth of a Penioillium from the globules of milk. - We talk of, and admire very properly, the beautiful flowers of the air-plants grown in greenhouses, forgetting that nothing can be more varied than the common lichens which grow so profusely on our fence rails, rocks, and elsewhere, deriving their nourishment from the air, and assuming most curious hygrometrioal variations - some, of the richest golden yellow, others with tiny goblets, the borders studded with crimson shields. In the tropios, they lay hold of evergreen leaves; their chosen climate is one that is temperate and moist; aspects to the north or west are their favorite resort, for they shun the rays of the noontide sun. They are met with to the limits of eternal snow.

With a good microscope, a student might pass his life in their study alone. - From kelp (the product of a sea-weed) a useful article for the soap-boiler and glass-maker is produced, and sea-wracks (as they are called) thus take their place among valuable vegetation; their soda makes useful manures, and in medicine they are occasionally employed. Their medical value seems to be owing to the presence of iodine, which is known to be a powerful remedy in cases of goitre, etc. The burnt sponge formerly administered, probably owed its efficacy to the iodine it contained; and it is a curious fact, that the stems of a sea-weed are sold in the shops, and chewed by the inhabitants of South America wherever goitre is prevalent, for the same purpose. This remedy is termed by them, Palo-coto (literally, Goitre-stick). - Fungi, including mushrooms, have engaged the attention of various naturalists; they are important either as food or as poison, or as parasites destructive of plants on which they grow. As food, the most valuable are the Agaricus campestris, or common Mushroom, the various species of Helvella, or Morel, and the Truffle; but a considerable number of other kinds are used as food in various parts of the world, of which a useful account will be found in De Candolle's excellent Essai $ur les Propreiles des Plantes; Persoon, Greville, and other authors, have found them a prolific topic.

The decay of fruit appears, in a great measure, to be produced by them. The Rhizomorpha (a spurious genus) vegetates in dark mines, far from the light of day, and is remarkable for its phosphorescent properties. In the coal mines in Saxony, the species are described as giving those places the air of an enchanted castle; the roof, walls, and pillars, are entirely covered with them, their beautiful light almost dazzling the eye, the light increasing with the temperature of the mine. - Dr. Gray says, in one of his essays, "no idea is more fallacious than that those who know a little of a scienoe may be qualified to write elementary books for those who know nothing. Those who have but a pittance of scientific knowledge had best give God thanks, and make no boast of it; and as for their writing, let that appear when there is no need of such vanity." - Mr. Bateham gives a slashing review of Hooper's Fruit Book in the Ohe Cultivator; to this the editor adds the following: "Note. Bro. Bateham puts it to Father Hooper right strong.

We fear he hae struck a hollow tooth into a crab or persimmon, lately, that makes him write so savagely".
