Lord Grey addresses his letter to the Prince, and not to the King; though the King, as well as the Prince, had commissioned him to put down the rising disturbances in his neighbourhood.[95] Some, perhaps, may think this intelligible on the ground that Lord Grey wrote to Henry as Prince of Wales, and therefore more immediately (p. 086) intrusted with the preservation of its peace. But his suggestion to the Prince to take the advice of the King's council,--"with advice of our liege lord his council,"--is scarcely consistent with the idea of the King himself being at hand to give the necessary directions and a "more plainer commission." [Footnote 91: Chroniclers give an account of an extraordinary instrument of death laid in Henry's bed by some secret plotter against his life. The Sloane Manuscript describes it as a machine like the engine called the Caltrappe; and the Monk of Evesham says that it was reported to have been laid for Henry by one of Isabella's household.] [Footnote 92: Modern writers have erroneously referred to this year Monstrelet's account of Henry of Monmouth's expedition to Scotland.] [Footnote 93: A curious item in the Pell Rolls (14 December 1401) intimates that Henry IV. amused himself with the sports of the field, and at the same time tells us that such amusements were by no means unexpensive in those days: "Sixteen pounds paid by the King to Sir Thomas Erpyngham as the price of a sparrow-hawk."] [Footnote 94: June 14, he wrote to his council from Clipstone in Nottinghamshire: July 4th, he was at York.--Min. Council.] [Footnote 95: "By our liege Lord his commandment, and by yours."] * * * * *
