Mathews once personated a Spanish Ambassador; a frolic enacted by him at an inn at Dartford. An account of the freak was written by Tom Hill, who took part in the scene, acting as Mathews's interpreter. He called it his "Recollections of his Excellency the Spanish Ambassador's visit to Captain Selby, on board the _Prince Regent_ one of his Majesty's frigates stationed at the Nore, by the Interpreter." The party hired a private coach, of large capacity, and extremely showy, to convey them to Gravesend as the _suite_ of Mathews, who personated an ambassador from Madrid to the English Government, and four smart lads, who were entrusted with the secret by the payment of a liberal fee. The drivers proved faithful to their promise. When they arrived at the posting-house at Dartford, one of the drivers dismounted, and communicated to the inn-keeper the character of the nobleman (Mathews) inside the coach, and that his mission to London had been attended with the happiest result. The report spread through Dartford like wildfire, and in about ten minutes the carriage (having by previous arrangement been detained) was surrounded by at least two hundred people, all with cheers and gratulations, anxious to gain a view of the important personage, who, decked out with nearly twenty different stage jewels, representing sham orders, bowed with obsequious dignity to the assembled multitude. It was settled that the party should dine and sleep at the Falcon Tavern, Gravesend, where a sumptuous dinner was provided for his Excellency and _suite_. Previously, however, to dinner-time, and to heighten the joke, they promenaded the town and its environs, followed by a large assemblage of men, women, and children at a respectful distance, all of whom preserved the greatest decorum. The interpreter (Mr. Hill) seemed to communicate and explain to the Ambassador whatever was of interest in their perambulation. On their return to the inn, the crowd gradually dispersed. The dinner was served in a sumptuous style, and two or three additional waiters, dressed in their holiday clothes, were hired for the occasion.
