“...the Perdrix. It was the custom, in those troubled days of warfare, for boats to row backwards and forwards across the harbour during the hours of night, the sailors of the different ships in the dock, headed by one of their officers, taking it by turns to keep this watch ; and the sleeper might often be roused from his dreams as the deep-toned " All's well" resounded through the still night air. Lord Camelford and Lieutenant Peterson were, unhappily, at variance ; and, perhaps to mortify his rival, Lord Camelford ordered Mr. Peterson to take the watch upon the very evening that a gay ball was to be given at Black’s Point to the naval officers.

Des- salines was made Governor for life, but later in the year he proclaimed himself Emperor. He was assassinated in 1806, and two rival chiefs, Cristophe and Pétion, established themselves in the north and south respectively; while the Spaniards took the eastern portion óf the island, which they called Santo Domingo. Pétion died in 1818, and, Cristophe having committed suicide in 1820, General Boyer became master of the whole of the western end of the island, and in 1822, taking advantage of dissension in the Spanish part, he invaded it and captured the whole of it. The entire island was then called Haiti, but in 1843 Boyer was driven out by a revolution, and in 1844 the people in the eastern part established the Dominican...”
