'We think the annual increase, as computed by Capt. Stuart, too low by 10 or 15,000. The estimate also of the expense of transportation is much below the actual cost. Besides, there is no provision made for the support of these helpless beings after their arrival in Africa, until they could provide for their own wants. Double the cost of transportation would be required for their subsistence till they could maintain themselves, without making any provision for implements of husbandry, mechanics' tools, &c. &c. without which they would all perish, even without the help of a pestiferous climate. But yet the table shows at one view the utter futility of the whole scheme of African Colonization. Slavery can no more be removed by these means than the waters of the Mississippi can be exhausted by steam engines. And the removal of slavery is the great consummation to which all benevolent efforts for benefitting the African race in this country, should ultimately tend. All schemes that do not promote this end will prove futile, and will end in disappointment. The axe must be laid to the root of the corrupt tree. It is a system that admits of no palliation, no compromise.'—['Herald of Truth,' Philadelphia.]
