Meanwhile, there were trials for high treason at Westminster Hall; trials of rioters at York and Derby; and at the latter town, on the 7th of November, three miserable men were hung. Among the witnesses at these trials appear to have been two men named Castle and Oliver: and it came out that these fellows, with two other Government spies, named Edwards and Franklin, had been among the chief fomenters by speeches and writings of the seditions in the Metropolis and northern counties. The disclosures made by these scoundrels produced of course a great sensation and numerous satires. One of these, entitled, _More Plots!!! More Plots!!!_ published by Fores in August, 1817, is "dedicated to the inventors, Lord S [idmouth] and Lord C [astlereagh]." It is divided into four compartments. In the first we see four foxes (typifying no doubt the four informers) watching the movements of a flock of geese. "'Tis plain," says one of the former, "there is a plot on foot; let's seize them, Brother Oliver." "I have no doubt of it: I can smell it plainly," answers his companion. In the second, a couple of fierce nondescript beasts are regarding a number of innocent lambs: "These bloodthirsty wretches," remarks one of the two, "mean to destroy man, woman, and child, I know it to a certainty; for they carry sedition, privy conspiracy, and rebellion in their looks." "And I'll swear it, Brother Castle," says his companion; "let's dash at them." In the third, a cat watches the movements of some unsuspecting mice: "There's a pretty collection of rogues gathered together," observes Grimalkin; "if there is not a plot among them, burn my tail and whiskers." In the last, we behold a Kite just about to pounce on some chicken: "The world's over-run with iniquity," says the bird of prey; "and these troublesome miscreants will not let honest hawks sleep in security." We shall return to the subject of these Government spies and the troubles of 1817 in the graphic satires of George Cruikshank. EDMUND KEAN AND BOOTH.
