A New-York ship, the Flying Cloud, made the passage round the Horn to San Francisco in ninety days--shorter than any voyage on record. Her fastest day's run was 374 miles, beating the fleetest of Collins's steamers by fifty miles. In three successive days she made 992 miles. At this rate she would cross the Atlantic in less than nine days. Discouraging accounts have been received respecting the whale fleet in the North Pacific Ocean. After wintering in the gulf of Anadir, the fleet attempted to pass into the Arctic Ocean, when it became surrounded with fields of ice, by which not less than eight vessels are known to have been destroyed, and it was supposed that upwards of sixty others had experienced the same fate. Some of the crews of the lost ships reached the main land, but afterwards got into difficulty with the natives and in consequence many of them were killed. The whale fishing, during the season, is said to have been an entire failure, and a number of vessels were on their return to the northwest coast, in the hope of retrieving their ill fortune. Several disastrous "accidents" have recently happened in various parts of the country. On the 21st September, the steamer James Jackson, exploded near Shawneetown in Illinois, killing and wounding 35. On the 26th September, the Brilliant exploded near Bayou Sara, killing a yet larger number; and many such events of less importance, but probably involving more or less criminality, have occurred on steamboats and railroads in various parts of the country. The most destructive fire since the completion of our last number was one at Buffalo, commencing on the 25th September, and continuing until 200 buildings, on more than 30 acres, were destroyed, and an immense number of poor families were made homeless. The fire extended over the meanest part of the town, but the loss is estimated at $300,000. For several days a destructive gale prevailed along the eastern coast, producing an immense loss of life; a large number of dead bodies were taken from the holds of vessels. Great excitement has prevailed in Gloucester, Newburyport and other towns, a large portion of whose populations were exposed to the fury of the storm. Further east, on the coast of Nova-Scotia, the remains of sixty persons, lost during the storm, are said to have been buried in one grave. No less than 160 vessels, of all kinds, are reported to have been wrecked. The Grand Jury sitting at Philadelphia have found bills of indictment against four white men and twenty-seven negroes, for treason, in participating in the outrage at Christiana, in the state of Pennsylvania. At Syracuse on the 1st of October an attempt was made to rescue a slave, but he was captured and his abettors arrested and conveyed to Auburn for examination.
