upon plantations, and upon great public works. It was revived—but against great opposition. From the beginning of the revival there were protests, and they grew. The revival was counter to the new conscience of mankind. In some respects the new gang slavery was worse than anything in the ancient world. Peculiarly horrible was the provocation by the trade of slave wars and man hunts in Western Africa, and the cruelties of the long transatlantic voyage. The poor creatures were packed on the ships often with insufficient provision of food and water, without proper sanitation, without medicines. Many who could tolerate slavery upon the plantations found the slave trade too much for their moral digestions. Three European nations were chiefly concerned in this dark business, Britain, Spain, and Portugal, because they were the chief owners of the new lands in America. The comparative innocence of the other European powers is to be ascribed largely to their lesser temptations. They were similar communities; in parallel circumstances they would have behaved similarly.
Throughout the middle part of the eighteenth century there was an active agitation against negro slavery in Great Britain as well as in the States. It was estimated that in 1770 there were fifteen thousand slaves in Britain, mostly brought over by their owners from the West Indies and Virginia. In 1771 the issue came to a conclusive test in Britain before Lord Mansfield. A negro named James Somersett had been brought to England from Virginia by his owner. He ran away, was captured, and violently taken on a ship to be returned to Virginia. From the ship he was extracted by a writ of habeas corpus. Lord Mansfield declared that slavery was a condition unknown to English law, an "odious" condition, and Somersett walked out of the court a free man.
The Massachusetts constitution of 1780 had declared that "all men are born free and equal." A certain negro, Quaco, put this to the test in 1783, and in that year the soil of Massachusetts became like the soil of Britain, intolerant of slavery; to tread upon it was to become free. At that time no other state in the Union followed this example. At the census of 1790, Massachusetts, alone of all the states, returned "no slaves."
The state of opinion in Virginia is remarkable, because it brings to light the peculiar difficulties of the southern states. The great
