Long after this period—in 1738—the Earl of Ilay, writing to Sir Robert Walpole from Edinburgh, said: ‘I am forced to send this letter by a servant twenty miles out of town, _where the Duke of Argyle’s attorney cannot handle it_.’ It sounds strangely that Lord Hay should thus have had to complain of his own brother; that one who was supreme in Scotland, should have been under such a difficulty from an opposition noble; and that there should have been, at so recent a period, a disregard to so needful a principle. But this is not all. Lord Ilay, in time succeeding his brother as Duke of Argyle, appears to have also taken up his part at the Edinburgh Post-office. In March 1748, General Bland, commander of the forces in Scotland, wrote to the Secretary of State, ‘that his letters were opened at the Edinburgh Post-office; and I think this is done _by order of a noble duke_, in order to know my secret sentiments of the people and of his Grace. If this practice is not stopped, the ministers cannot hope for any real information.’ Considering the present sound administration of the entire national institution by the now living inheritor of that peerage, one cannot without a smile hear George Chalmers telling[323] how the Edinburgh Post-office, in the reign of the second George, was ‘infested by two Dukes of Argyle!’ It will be heard, however, with some surprise, that the Lord Advocate may still be considered as having the power, in cases where the public interests are concerned, to order the examination of letters in the Post-office. So lately as 1789, when the unhappy duellist, Captain Macrae, fled from justice, his letters were seized at the Post-office by order of the Justice-clerk Braxfield. The sport of cock-fighting had lately been introduced into Scotland, and a cock-pit was now in operation in Leith Links, where the charges for admission were 10_d._ for the front row, 7_d._ for the second, and 4_d._ for the third. Soon after, ‘the passion for cock-fighting was so general among all ranks of the people, that the magistrates [of Edinburgh] discharged its being practised on the streets, on account of the disturbances it occasioned.’[324] [Sidenote: 1702.] William Machrie, who taught in Edinburgh what he called ‘the severe and serious, but necessary exercise of the sword,’ had also given a share of his attention to cock-fighting—a sport which he deemed ‘as much an art, as the managing of horses for races or for the field of battle.’ It was an art in vogue over all Europe—though ‘kept up only by people of rank, and never sunk down to the hands of the commonalty’—and he, for his part, had studied it carefully: he had read everything on the subject, conversed and corresponded on it with ‘the best cockers in Britain,’ carefully observing their practice, and passing through a long experience of his own.
