The _Post-Office_, which is the agent not only of commerce, but of civilization, joins in the uniform testimony. According to the tables for 1859, the postage collected in the Free States was $5,581,749, and the expense of carrying the mails $6,945,545, leaving a deficit of $1,363,796. In the Slave States the amount collected was only $1,936,167, and the expense of carrying the mails $5,947,076, leaving the enormous deficit of $4,010,909,--the difference between the two deficits being $2,647,113. The Slave States did not pay one third of the expense in transporting their own mails; and not a single Slave State paid for transporting its own mails, not even the small State of Delaware. Massachusetts, besides paying for hers, had a surplus larger by one half than the whole amount collected in South Carolina. According to the census of 1850, the value of _churches_ in the Free States was $66,177,586; in the Slave States, $20,683,265. The _voluntary charity_ contributed in 1855, for certain leading purposes of Christian benevolence, was, in the Free States, $955,511; for the same purposes in the Slave States, $193,885. For the Bible cause the Free States contributed $321,365; the Slave States, $67,226. For the Missionary cause the former contributed $502,174; and the latter, $101,934. For the Tract Society the former contributed $131,972; and the latter, $24,725. The amount contributed for Missions by Massachusetts was greater than that contributed by all the Slave States, and more than eight times that contributed by South Carolina. Nor have the Free States been backward in charity for the benefit of the Slave States. The records of Massachusetts show that as long ago as 1781, at the beginning of the Government, there was a contribution throughout the Commonwealth, under the particular direction of that eminent patriot, Samuel Adams, for the relief of inhabitants of South Carolina and Georgia.[49] In 1855 we were saddened by the prevalence of yellow fever in Portsmouth, Virginia; and now, from a report of the Relief Committee of that place, we learn that the amount of charity contributed by the Slave States, exclusive of Virginia, the afflicted State, was $12,182; and including Virginia, it was $33,398; while $42,547 was contributed by the Free States. In all this array we see the fatal influence of Slavery. But its Barbarism is yet more conspicuous, when we consider its _Educational Establishments_, and the unhappy results naturally ensuing from their imperfect character.
