The London _Herald_ declares that 'America is a nuisance among nations!' When they undertake to meddle with us, they will find us one. We would not leave them a ship on the sea or a seaboard town un-ruined. The whole world would wail one wild ruin, and there should be the smoke as of nations, when despotism should dare to lay its hand on the sacred cause of freedom. For we of the North are living and dying in that cause which never yet went backward, and we shall prevail, though the powers of all Europe and all the powers of darkness should ally against us. Let them come. They do but bring grapes to the wine-press of the Lord; and it will be a bloody vintage which will be pressed forth in that day, as the great cause goes marching on. * * * * * Let no one imagine that our military draft has been one whit too great. Our great folly hitherto has been to underrate the power of the enemy. In the South every male who can bear arms is now either bearing them or otherwise directly aiding the rebellion. When the sheriffs of every county in the seceding States made their returns to their Secretary of War, they reported one million four hundred thousand men capable of bearing arms. And they have the arms and will use them. It is 'an united rising of the people,' such as the world has seldom seen. But then it is _all_ they can do--it is the last card and the _last_ man, and if we make one stupendous effort, we must inevitably crush it. There is no other course--it is drag or be dragged, hammer or anvil now. If we do not beat _them_ thoroughly and completely, they will make us rue the day that ever we were born. The South is stronger than we thought, and its unity and ferocity add to its strength. It will never be conciliated--it must be crushed. When we have gained the victory, we can be what our foes never were to us--generous and merciful. * * * * * A GENTLEMAN of Massachusetts, who has held a position in McClellan's army that gave him an opportunity to know whereof he speaks, states that for weeks, while the army on the Peninsula were in a grain-growing country, surrounded by fields of wheat and oats belonging to well-known rebels, the Commissary Department was not allowed to turn its cattle into a rich pasturage of young grain, from the fear of offending the absent rebel owners, or of using in any way the property of Our Southern Brethren in arms against us. The result was, that the cattle kept with the army for the use of our hard-worked soldiers, were penned up, and half-starved on the forage carried in the regular subsistence trains, and the men got mere skin and bones for beef. * * * * *
