A.D. 1791, a tremendous earthquake was felt in Sicily, which destroyed many lives and much property; it was equal in severity to the shock experienced the year before at Borgo di San Sepolcro, during which an opening in the earth swallowed up many houses with their inhabitants. On the 2nd of February, this year, the Thames rose to an extreme height, and overflowed many parts of Westminster. A.D. 1792. This was a pestilential year in Egypt; it is recorded that 800,000 persons died from plague. The winter of the previous year, 1791, was very severe, and the spring wet and rainy in the southern parts of the United States; the summer was cold up to June, cold north-west winds prevailing. In May and June, locusts appeared in the State of New York, and devoured the grain; the wheat insect continued its ravages with great destruction to the crops in Long Island and also in Maryland and north of the Elk ridge. In the month of July, yellow fever raged terribly, causing great mortality in the city of Charleston. A kind of caterpillar destroyed the lime-trees in Philadelphia, and in the month of August, scarlet fever carried off numbers in that city, as well as in New York, and in a place called Bethlem. A.D. 1793, the spring was dry, the summer intensely hot and showery, with hail, and the autumn dry and cold. A fatal dysentery swept off vast numbers in Georgetown, Coventry; a nervous fever was prevalent at a place called Fairfield. Yellow fever raged to an alarming extent in Philadelphia, carrying off in the course of four or five months upwards of 4000 persons: it was also fatal in Boston. In the following year it prevailed in Baltimore, and at Norfolk in Virginia. About this period a similar epidemic caused great destruction in the island of Dominica and other of the West Indian islands: in Dominica it continued for three years, until 1796.
