What then must be done to avert the dread catastrophe? Action, immediate and energetic action, in the field and in Congress. Winter is the best season for a campaign in the South. On--on--on with the banner of the Republic, by land and sea, and with all the reinforcements, from the Ohio and Potomac to the Gulf. On, also, with the necessary measures in Congress to save our finances from ruin, arrest the depreciation of our national currency, and restore the public credit. We are upon the verge of ruin. We are hanging over the gulf of an irredeemable paper system, and its spectral shade, repudiation, is seen dimly in the dark abyss. The present Congress may save us; but what of the next? Would they, if they could? Who can answer? Can they, if they would? No! no! It will then be _too late_. Never did any representative assembly encounter so fearful a responsibility as the present Congress. Each member must vote as if the fate of the Union and of humanity depended upon his action. He must rise above the passing clouds of passion and prejudice, of State, local, or selfish interests, into the serene and holy atmosphere, illumined by the light of truth, and warmed by the love of his country and of mankind. His only inquiry must be, What will save the nation? The allegiance to the Union is paramount, its maintenance 'the supreme law,' the _lex legum_, of highest obligation, and he who, abandoning this principle, follows in preference any real or supposed State policy, is a secessionist in action, and a traitor to his country and mankind. Should the catastrophe happen, no such paltry motives will save him from disgrace and infamy; and, if he be snatched from oblivion, his only epitaph will be: Here lies a destroyer of the American Union. He did not destroy it by bullets, but by votes. He did not march against it with armed battalions; but, a sentinel, he slept on the post of duty, and--his country fell. What, then, can Congress do? They can consider _at once_ this great financial question, uninterrupted by any other measure, until there shall have been action complete and decisive. But two months more remain of the session. Not another day nor hour must be lost. All admit that something must be done, and done quickly.
