We have recently conversed with two gentlemen who, to save themselves from the poverty and disgrace of slavery, left North Carolina six or seven years ago, and who are now residing in the territory of Minnesota, where they have accumulated handsome fortunes. One of them had traveled extensively in Kentucky, Missouri, Ohio, Indiana, and other adjoining States; and, according to his account, and we know him to be a man of veracity, it is almost impossible for persons at a distance, to form a proper conception of the magnitude of the difference between the current value of lands in the Free and the Slave States of the West. On one occasion, embarking at Wheeling, he sailed down the Ohio; Virgina and Kentucky on the one side, Ohio and Indiana on the other. He stopped at several places along the river, first on the right bank, then on the left, and so on, until he arrived at Evansville; continuing his trip, he sailed down to Cairo, thence up the Mississippi to the mouth of the Des Moines; having tarried at different points along the route, sometimes in Missouri, sometimes in Illinois. Wherever he landed on free soil, he found it from one to two hundred per cent. more valuable than the slave soil on the opposite bank. If, for instance, the maximum price of land was eight dollars in Kentucky, the minimum price was sixteen in Ohio; if it was seven dollars in Missouri, it was fourteen in Illinois. Furthermore, he assured us, that, so far as he could learn, two years ago, when he traveled through the States of which we speak, the range of prices of agricultural lands, in Kentucky, was from three to eight dollars per acre; in Ohio, from sixteen to forty; in Missouri, from two to seven; in Illinois, from fourteen to thirty; in Arkansas, from one to four; in Iowa, from six to fifteen. In all the old slave States, as is well known, there are vast bodies of land that can be bought for the merest trifle. We know an enterprising capitalist in Philadelphia, who owns in his individual name, in the State of Virginia, _one hundred and thirty thousand acres_, for which he paid only _thirty-seven and a half cents_ per acre! Some years ago, in certain parts of North Carolina, several large tracts were purchased at the rate of _twenty-five cents_ per acre! Hiram Berdan, the distinguished inventor, who has frequently seen freedom and slavery side by side, and who is, therefore, well qualified to form an opinion of their relative influence upon society, says:
