DESCRIBING THE SOUTH IN TWELVE LINES, DEFINING THE CITIZEN'S FIRST DUTY, AND RECITING A PARODY. WASHINGTON, D.C., April --, 1861. The chivalrous South, my boy, has taken Fort Sumter, and only wants to be "let alone." Some things of a Southern sort I like, my boy; Southdown mutton is fit for the gods, and Southside particular is liquid sunshine for the heart; but the whole country was growing tired of new South wails before this, and my present comprehensive estimate of all there is of Dixie may be summed up in twelve straight lines, under the general heading of REPUDIATION. 'Neath a ragged palmetto a Southerner sat, A-twisting the band of his Panama hat, And trying to lighten his mind of a load By humming the words of the following ode: "Oh! for a nigger, and oh! for a whip; Oh! for a cocktail, and oh! for a nip; Oh! for a shot at old Greeley and Beecher; Oh! for a crack at a Yankee school-teacher; Oh! for a captain, and oh! for a ship; Oh! for a cargo of niggers each trip." And so he kept oh-ing for all he had not, Not contented with owing for all that he'd got. In view of the impending conflict, it is the duty of every American citizen, who has nothing else to do, to take up his abode in the capital of this agonized Republic, and give the Cabinet the sanction of his presence. Some base child of treason may intimate that Washington is not quite large enough to hold every American citizen; but I'm satisfied that, if all the democrats could have one good washing, they would shrink so that you might put the whole blessed party into an ordinary custom house. Some of the republicans are pretty large chaps for their size, but Jeff Davis thinks they can be "taken in" easily enough; and I know that the new tariff will be enough to make them contract like sponges out of water. The city is full of Western chaps, at present, who look as if they had just walked out of a charity-hospital, and had not got beyond gruel diet yet. Every soul of them knew old Abe when he was a child, and one old boy can even remember going for a doctor when his mother was born. I met one of them the other day (he is after the Moosehicmagunticook post-office), and his anecdotes of the President's boyhood brought tears to my eyes, and several tumblers to my lips. He says, that when Abe was an infant of sixteen, he split so many rails that his whole county looked like a wholesale lumber-yard for a week; and that when he took to flat-boating, he was so tall and straight, that a fellow once took him for a smoke-stack on a steamboat, and didn't find out his mistake until he tried to kindle a fire under him. Once, while Abe was practising as a lawyer, he defended a man for stealing a horse, and was so eloquent in proving that his client was an honest victim of false suspicion, that the deeply-affected victim made him a present of the horse as soon as he was acquitted.
