Since the abolition of slavery in the British dominions, no trouble has arisen, no danger been feared or apprehended. A thousand John Browns, each with nineteen white men and five black men, could not cause any tumult in any part of the British West Indies. Why is it, then, that one John Brown and company have created so wide-spread an alarm and consternation throughout the Slave States? The Governor of South Carolina has sent a dispatch (Nov. 21) to Gov. Wise, tendering any amount of _military aid to the defence of Virginia!_ Gov. Wise had several companies of the military present on the day of the execution of John Brown and others, and assured the Governor of South Carolina that Virginia is able to defend herself. What causes all this tumult and apprehension? SLAVERY! And yet, strange as it may seem, the Virginians, with a stupidity and infatuation which no language can describe, are seriously discussing the propriety of enslaving the free negroes of that State. Such a proceeding would resemble a physician who should order a dose of arsenic to cure a patient who had taken strychnine, or attempt to extinguish a conflagration by throwing oil on the flames. How the consequences of abolishing slavery would be dreadful and horrible, neither history nor experience informs us. Let us, then, see what they tell us of the consequences of holding men in bondage. In every instance which has fallen under my notice, insurrections have always been projected and carried on by slaves, and never (with the exception of Denmark Vesey in 1822, in Charleston, S. C.) by the free blacks. The contest between truth and falsehood, right and wrong, justice and injustice, has always continued from the earliest ages to the present moment. More especially is it true concerning American slavery, that "sum of all villanies," a crime which involves the continual violation of every one of the Ten Commandments. I propose, therefore, to give, with other incidents, an abstract of some of the attempts of the oppressed to throw off the yoke which held them, or threatened to hold them, in bondage. The first instance which has come to my knowledge in this country of an insurrection on a small scale, occurred on Noddle's Island, now East Boston, in 1638. In John Josselyn's account of his first voyage to New England may be found the following. Having previously stated that he was a guest of "Mr. Samuel Maverick, the only hospitable man (as he says) in all the country, giving entertainment to all comers gratis," he thus writes:--
