As a general remark, then, it may be observed that whenever from circumstances of soil, climate, and production, there is need of economy, skill, and careful industry in the cultivation of the ground; wherever nature, not yielding her fruits to indolent hands, has to be overcome by sturdy efforts, by labor directed by intelligence and aided at every turn by the appliances of art which inventive genius has discovered and adapted to use--there Slavery can not permanently exist, because it is incompatible with such conditions. In this view it may be seen how it has happened that Slavery, once adopted in the northern States, failed to flourish there--how it was cast out as an uncongenial element. In this same view it may be seen also that Slavery must, by and by, cease to exist in Maryland. It has brought sterility already upon whole districts; it rests like a paralysing spell upon the enterprise and the active energies of the commonwealth. Of this, more as we proceed. In the sugar and cotton growing States the products of the soil are so rich and abundant, that Slavery can exist in spite of the slovenly and wasteful manner in which its agency is employed. Yet even under these circumstances its profits are for the most part fallacious. No portion of the United States suffered so severely under the commercial revulsion of 1837 as the cotton and sugar growing region. The statistics of bankruptcies in Jamaica, as exhibited in reports to Parliament from time to time, show the same fact. Again, the use of slave labor is deemed essential in hot climates. The productiveness of the British West India Islands certainly was impaired by the abolition of Slavery; nor can it be disguised that the British government is now attempting to substitute another species of Slavery, or Slavery under another name, in place of that which was abolished. If the emancipated slaves had shown a willingness to work; if they had been sufficiently advanced to appreciate freedom so far as to know that in their own industry lay the real elements of independence--the result of the Emancipation Act of the British Parliament would have been different from what it has thus far appeared to be. There would have been laborers enough; but laborers of such a sort that the white proprietors, a handful in the general population, would have been supplanted--and that ere now. The energy which would have impelled the Jamaica negroes to work of their own accord; the spirit which would have sustained them; if that energy and spirit had existed; would have made them masters of the island.
