The manifesto had its effect, for it is a remarkable fact that they who promise more than it is possible to perform, find the greatest favour with the populace; for an undertaking to do what cannot be done always affords something to look forward to. Expectation is generally disappointed by fulfilment, and the most successful impostors are consequently those who promise the most impracticable things without ever doing anything. The imposition cannot be detected until the impossibility of the thing promised is demonstrated; and this does not often happen, for the difficulty of proving a negative is on all hands admitted. It was therefore a happy idea of Hereford, as a political adventurer, to promise a redress of every grievance; and if he could have added to his pledge of interference _de omnibus rebus_ an assurance of his ultimately applying his panacea to _quodam alia_, there is little doubt that he would have been even more successful than he was in augmenting the number of his followers. By the time he reached London he had got sixty thousand men of all sorts and sizes about him, for the people in those days were fond of changing their leaders, and Hereford was popular as the latest novelty. The Duke of York--the king's uncle--moved to the West End, as Henry and his forces entered at the East; but Henry of Bolingbroke--alias Hereford, who was also the nephew of York--invited the latter to a conference. After talking the matter over, the worthy couple agreed to a coalition; the conduct of York being very like that of an individual left to guard a house, and joining with the thief who came to rob the premises.
