The passage of the bill for employing the services of 300,000 slaves as soldiers, has alarmed the Yankees beyond measure. Nothing could exceed the exultation of the New editors when it failed, on the first trial, and nothing can surpass their chagrin at present. The New York Herald rails against the law in its usual style of exaggeration, quoting from Senator Hunster, whom it holds to be the true representative of the genuine secession party. It is very kind of the Herald, to take our affairs into its own keeping; but we beg leave to decline its interference. It asks, what we are now fighting for, since the nigger has been turned into a soldier? We are fighting to drive from our soil the most infamous race that God, in His wrath with mankind, ever permitted to cumber the earth. We are fighting to get rid of the Yankees? Surely, that is enough. The thieves and freebooters whom the Yankees facetiously style soldiers, are still thick around us as autumn leaves in Valambrosa. Therefore we are fighting.
