"I shall not imitate the example of other gentlemen by making professions of my love of liberty and abhorrence of slavery, not, however, because I do not entertain them. I am an enemy to slavery." THE VOICE OF MARYLAND. Slavery has little vitality in Maryland. Baltimore, the greatest city of the South--greatest because freest--has a population of more than two hundred thousand souls, and yet less than three thousand of these are slaves. In spite of all the unjust and oppressive statutes enacted by the oligarchy, the non-slaveholders, who with the exception of a small number of slaveholding emancipationists, may in truth be said to be the only class of respectable and patriotic citizens in the South, have wisely determined that their noble State shall be freed from the sin and the shame, the crime and the curse of slavery; and in accordance with this determination, long since formed, they are giving every possible encouragement to free white labor, thereby, very properly, rendering the labor of slaves both unprofitable and disgraceful. The formation of an Abolition Society in this State, in 1789, was the result of the influence of the masterly speeches delivered in the House of Delegates, by the Hon. William Pinkney whose undying testimony we have already placed on record. Nearly seventy years ago, this eminent lawyer and Statesman declared to the people of America, that if they did not mark out the bounds of slavery, and adopt measures for its total extinction, it would finally "work a decay of the spirit of liberty in the free States." Further, he said that, "by the eternal principles of natural justice, no master in the State has a right to hold his slave in bondage a single hour." In 1787, Luther Martin, of this State, said:-- "Slavery is inconsistent with the genius of republicanism, and has a tendency to destroy those principles on which it is supported, as it lessens the sense of the equal rights of mankind, and habituates us to tyranny and oppression."
