That we may learn something of the importance of cities in general, let us look for a moment at the great capitals of the world. What would England be without London? What would France be without Paris? What would Turkey be without Constantinople? Or, to come nearer home, what would Maryland be without Baltimore? What would Louisiana be without New Orleans? What would South Carolina be without Charleston? Do we ever think of these countries or States without thinking of their cities also? If we want to learn the news of the country, do we not go to the city, or to the city papers? Every metropolis may be regarded as the nucleus or epitome of the country in which it is situated; and the more prominent features and characteristics of a country, particularly of the people of a country, are almost always to be seen within the limits of its capital city. Almost invariably do we find the bulk of the floating funds, the best talent, and the most vigorous energies of a nation concentrated in its chief cities; and does not this concentration of wealth, energy, and talent, conduce, in an extraordinary degree, to the growth and prosperity of the nation? Unquestionably. Wealth develops wealth, energy develops energy, talent develops talent. What, then, must be the condition of those countries which do not possess the means or facilities of centralizing their material forces, their energies, and their talents? Are they not destined to occupy an inferior rank among the nations of the earth? Let the South answer. And now let us ask, and we would put the question particularly to Southern merchants, what do we so much need as a great Southern metropolis? Merchants of the South, slaveholders! you are the avaricious assassinators of your country! You are the channels through which more than one hundred and twenty millions of dollars--$120,000,000--are annually drained from the South and conveyed to the North. You are daily engaged in the unmanly and unpatriotic work of impoverishing the land of your birth. You are constantly enfeebling our resources and rendering us more and more tributary to distant parts of the nation. Your conduct is reprehensible, base, criminal.
