The crater Stromboli, which has been in activity since the most ancient times, presents at present the same appearances as those which were described by Spallanzani, in 1788. It is constantly filled with lava in a state of fusion, which alternately rises and falls in the cavity. Having ascended to ten or twelve yards below the summit of the walls, this boiling fluid is covered with large bubbles, which burst with noise, letting enormous quantities of gas escape from them, and projecting on all sides scoriaceous matter. After these explosions, it again subsides, but only to rise again and produce like effects--these alternations being repeated regularly at intervals of some minutes. In craters where the lava is less fluid than in that of Stromboli, new cones are sometimes formed in the midst of the Crater, which first rise in the form of a dome, and then burst out so as to form a small active volcano in the middle of the crater of the great one. This phenomenon is often presented within the crater of Vesuvius, and was more particularly witnessed in 1829. LOAF SUGAR. In 1553 a sugar-loaf was presented to Mr. Waldron, of Bovey House, which weighed 7 lbs., at 1s. 1d. per lb. (7s. 7d.) The late Lord Rolle married the last of that branch of the Waldron family. The house remains about ten miles west of Lyme. The sugar-loaf was charged at a high rate, considering the greater value of money in Queen Mary's reign. This article began to be highly prized. The sugar-cane, which had been grown from the year 1148 in Sicily, had been imported into Madeira A.D. 1419. About the year 1503 the art of refining sugar, before called "blanch powdre," was discovered by a Venetian; before which the juice, when selected instead of honey for sweetening, was used as it came from the cane. Only twenty-seven years from this date, in 1526, it was imported from St. Lucar in Spain by Bristol merchants. Let not the present of the Mayor of Lyme be considered as a cheap article produced in abundance in the islands of the West Indies. The sugar-cane was not imported thither into Barbadoes from the Brazils till the year 1641. How surprising the result of official inquiries in the year 1853 into the consumption of sugar! It amounted to 7,523,187 cwts., or 30 lbs. each individual of the United Kingdom. SUSPENSION BRIDGES AT FREYBOURG.
