The Anti-Slavery Monthly Reporter for September, among the advantages which will probably lead to the discontinuance of the cultivation of sugar by slaves, enumerates the rapid extension of the manufacture of beet-root sugar in France; a prelude, as the editor conceives, to its introduction into this country, and especially into Ireland.
Dry Rot.
The American Commodore Barron recommends pumping air from the holds of vessels as a remedy against dry rot; the common mode of ventilation, by forcing pure air, or dashing water into the hold, being found an imperfect preservative.
Alloyed Iron Plate.
Iron, coated with an alloy of tin and lead, so as to imitate tin plate, and not to rust, is now manufactured to a considerable extent in Paris; and its use for sugar-pans and boilers, and in the construction of roofs and gutters is expected to be very considerable.
Interesting Question.
Whether in the sea there be depths where no creature is able to live, or whether a boundary be assigned to organic life within those depths, cannot be ascertained. It, however, clearly appears from the observations made by Biot, and other naturalists, that fishes, according to their different dispositions, live in different depths of the ocean.—From the German.
Cats.
In Kamtschatka, Greenland, Lapland, and Iceland, there are no cats, nor does the lynx in Europe extend farther than Norway.—Ibid.
