ASTOUNDING DEVELOPMENTS—ENGLISH FOREIGN POLICY—SYSTEM OF ESPIONAGE—MELANCHOLY RESULTS OF ABOLITION.

The rapid decline of the once flourishing Island of Jamaica—the immense demoralization of its once comparatively happy negro race, and their present depravity and idleness, resulting in the destruction of the fine town of Jamaica, are melancholy results of the sickly attempts at elevating a class of beings above their natural position, on the part of the British oligarchy. The £15,000,000, or $75,000,000, paid by the British people in 1835, as an indemnity to the planters of Jamaica, forms but a small portion of the losses sustained by the British empire, in an attempt to counteract the decrees of Providence. That insidious government does not, however, rest quiet under the severe blow which it has inflicted upon itself, but endeavors to counteract it by bringing similar disasters upon rival powers. Its emissaries have long been tampering with the slave population of Cuba, and some of them have been ejected the island by the authorities.

The attempts of England to separate the northern from the southern sections of the Union, have been as old as our government. The movements of the recent agents of the English government, in endeavoring to sow disaffection among the States, and of fomenting resistance to the authorities of the Union, were carried on to such an extent just previous to the last war, particularly with the State of Massachusetts, as to be the subject of a special message of President Madison, March 9, 1812.—The refusal of Massachusetts and Connecticut to answer the call for arming the militia, after that war was declared, was undoubtedly the result of that recent influence. The Hartford Convention and its alleged objects, are evidences of the lingering remnants of those attempts, and when during the war, the Governor of Bermuda promulgated a British order in council, authorizing trade under special licenses with the eastern cities only, her leading policy of seeking to conquer the United States, by sowing dissensions between the north and south, was proclaimed to the world. The unexpected result of that war, in which her hitherto unconquerable navy met with disaster in every engagement, put a new face on the matter. Until within a few years those attempts have been apparently at rest, recently, however, swarms of incendiary agents have spread themselves over the face of the continent, creating disaffection under the plea of philanthropy. Some twelve months since, secret government instructions were sent to every consul and British employee on this continent, to spy into and report upon the condition and strength of the black population in the minutest details. This espionage is now going forward with the greatest activity, spreading its ramifications into all sections. Coupling this with the recent declaration of the person M'Cauley, in the British Parliament, "that England should treat with the Northern States only," we have a demonstration that requires the utmost vigilance from every friend of his country. The recent interference of that proverbially treacherous government with our national institutions, with the view of creating disunion, was one of the leading causes that led to the late war, and was frequently alluded to in the communications of President Madison to Congress. In addition to these particulars, we have other information of a most important character, not yet ready for the public eye, but which will send a thrill through the continent, and startle the friends of their country at the dangers by which she is beset.
