"Disable my Patapsco!" exclaimed the indomitable old Neptune, in his iron-plated manner, "the insects have tied us fast,--bend my turrets if they haven't." At this time, my boy, the concentrated fire of the Fort was terrific, six horse-pistols being in full play at once, and the Mackerel with the quart measure amidships reporting that the turret of the "Shockingbadhat" had been hit three quarts of times in thirty seconds. Such being the case, and the European delegation having gone home with a view to shaking off their inclination to fall asleep, the stern old commander ordered a wet blanket to be thrown over his swivel-gun, and such of the iron-plated squadron as had not sunk were immediately run ashore. The affair had been merely a reconnoissance. Shortly after the conclusion of this terrible artillery duel, and a few minutes subsequent to a touching exchange of congratulations between the unconquerable Rear-Admiral and his venerable grandmother, there hastily arrived from Paris an obese middle-aged chap, in black cotton gloves and a scratch wig, and says he to the Admiral: "Allow me to bless you, Sir,--My name is Hunter, Sir,--for your excellent iron-clad conduct. We should all be grateful, sir, that you have passed safely through 'a concentric fire that has never heretofore had a parallel in the history of warfare.'" Never heretofore had a parallel! What could he have meant, my boy? How could a _concentric_ fire have a _parallel_ at any time? Yours, questioningly, ORPHEUS C. KERR. LETTER XCIII.
