Your young military men, who want to reap the harvest of laurels, don't care (I suppose) how many seeds of war are sown; but for the sake of humanity it is devoutly to be wished, that the manly employment of agriculture and the humanizing benefits of commerce, would supersede the waste of war and the rage of conquest; that the swords might be turned into plough-shares, the spears into pruning hooks, and, as the Scripture expresses it, "the nations learn war no more."
