It is not questionable that the productions and general prosperity of the island decreased under Boyer's administration. The blacks needed the stringent policy of some such tyrant as Christophe. And the popularity of Boyer was greatly lessened by his approval or direct negotiation of a treaty with France, by which he agreed to pay to that country an indemnity of 150,000,000 of francs, in five annual instalments. The French Government recognized the independence of Hayti, but it was impossible for Boyer to meet his engagements. He however conducted the administration with industry, discretion, and repose, for fifteen years, when a long-slumbering opposition, for his presumed preference of the mulatto to the black population in the dispensations of government favor, began to exhibit itself openly. When this feeling was manifested in the second chamber of the Legislature, in 1843, the promptness and decision with which he attempted to suppress it, induced an insurrection among the troops, and he was compelled to fly, with about thirty followers, to Jamaica. He afterward proceeded to London, and finally to Paris, where he lived quietly in the Rue de Madeline, enjoying the respect of many eminent men, and surrounded by attached followers who shared his exile, until the 10th of July. On the 12th he was buried with appropriate funeral honors. * * * * * THE DUKE OF CAMBRIDGE. The death of the Duke of Cambridge, brother of the late William IV., occurred the 8th of July, and was quite sudden. He was the seventh son of George III., was born in 1774, received his earliest education at Kew, and finished his studies at Gottingen. He entered the army, and experiencing much active service, was promoted, until in 1813 he attained the distinction of Field Marshal. He soon afterward became Governor-General of Hanover, and continued to fill that post until the accession of the Duke of Cumberland, in 1839. His subsequent life presented few features of much interest. His name was to be found as a patron and a contributor to many most valuable institutions, and he took delight in presiding at benevolent festivals and anniversary dinners, when, though without the slightest pretension to eloquence, the frankness and _bonhommie_ of his manners, and his simple straight-forward earnestness of speech, used to make him an universal favorite. He took but little part in the active strife of parties. He died in his seventy-seventh year, leaving one son, Prince George of Cambridge, and two daughters. * * * * * GEORGE W. ERVING. This distinguished public man died in New York, on the 22d ult. A correspondent of the _Evening Post_ gives the following account of his history:
