_May 31, 1806._ _A Diving Machine on a New Construction._ Published by T. Rowlandson, 1 James Street, Adelphi.--The unpopular increase of Taxation, levied under the Broad-bottom'd auspices, was severely dealt with by the satirists. In the present version, the Ministers are represented as the crew of a diving-barge, _The Experiment_. Fox is the diver, and a noble wreck, the 'Constitution cutter, John Bull commander,' has gone down to the bottom of the 'Ocean of Taxation.' Her commander is done for; amidst the spoils of the shipwreck, the Diver (Fox) is securing certain weighty additions to his treasury: pig-iron, Beer Tax, and heavy chests, '10 per cent.' are among the spoils. A rope is secured to the ponderous Property Tax; Fox is giving the word to 'Haul up;' Petty, Sheridan and others are hauling away at the ropes; their lighter is nearly filled with the precious wreckage they have been able to secure. _June 20, 1806._ _The Acquittal, or upsetting the Porter Pot._ Published by T. Rowlandson, 1 James Street, Adelphi.--Lord Melville and his counsel are exulting over the results of his acquittal by his peers of the charge of investing the public funds for his personal advantage, as far as the interest was concerned, a perquisite previously allowed to the Treasurer of the Navy. When Lord Melville, then Henry Dundas, filled the post of Treasurer to the Navy, he brought in an act for the better regulation of that office, making such employment of the funds in hand a misdemeanour; Whitbread, (at the head of the advanced Liberals, or 'Radical Reformers,' who began to make his party dreaded as formidable opponents of the old-fashioned Whig section, from which his supporters had receded), and Wilberforce, as the enemy of all corruptions, were the principal movers of Melville's impeachment, for the alleged breach of his own act. The two Scots, Melville and Trotter, who are dressed in Highland garb, are embracing fraternally; at the same time, Melville is giving a sly backward kick to a huge pewter pot, bearing the face of the disconcerted mover of the charges. _Whitbread's Entire Butt_ is knocked over, its contents _Impeachments_, _High Crimes_, _Misdemeanours_, and _Peculation_, are flowing away unheeded; 'What is life without a friend?' cries the ex-Minister on his acquittal; his counsel, Trotter, is assuring his relieved patron, 'I'll _trot_ for you! I'll gallop for you all over the globe. O happy day for Scotland! and see how pleased John Bull looks--ah Johnny, Johnny, this is indeed a glorious triumph.' But Mr. Bull declines to be soft-sawdered: his face is wearing anything but a satisfied expression; he significantly keeps his hands in his pockets, and is grumbling, 'I say nothing,' as if he could say a great deal if he were disposed to express his honest opinion of the entire transaction.
