now Earl of Leven, Scottish commander-in-chief for the third time, and tolerably well acquainted already with the North of England? Second in command to him, as Lieutenant-general of the Foot, was William Baillie, of Letham, in this post for the second time; and the Major-general, with command of the horse was David Leslie, a third Gustavus-Adolphus man, and, though a namesake of the commander-in-chief, only distantly related to him. The marquis of Argyle accompanied the invaders, nominally as Colonel of a troop of horse; and among the other colonels of foot or horse were the Earls of Cassilis, Lindsay, Loudoun, Buccleugh, Dunfermline, Lothian, Marischal, Eglinton, and Dalhousie. The expenses of the army, averaging 1,000_l._ per diem (6_d._ a day for each common foot-soldier, 8_d._ for a horse-soldier, and so on upwards) were, by agreement, to be charged to England. [Footnote: Rushw. V. 604-7; Parl. Hist. III. 200, 201; Baillie, II. 100 and 137.] The condition on which the Scots had consented thus to aid the English Parliament must not be forgotten. It was the agreement of the two nations in one and the same religious Covenant. In all the negotiations that had been going on between London and Edinburgh, the Scots had always assumed the fulfilment of this condition on the part of the English. And, so far, we have seen, it had already been fulfilled. Since September 1643, when Henderson's Covenant had first been proposed to the English Parliament and the Westminster Assembly, and the Commons and the Westminster Divines had set the example by swearing to it collectively in one of the London churches, "the Covenant" had been a phrase familiar to the English mouth. In all the miscellaneous activity of the Parliament for the detection and disabling of "Malignants," there had been no instrument more effective or more commonly used. There were other tests and oaths by which the "malignants" might be distinguished from the "well-affected"; but the taking or not taking of the Solemn League and Covenant was the test paramount. Wherever the Parliament had power it had been in operation. Since December 20, for example, it had been the law that no one could be a Common Councilman of the City of London who had not subscribed to the Covenant. Still, in this matter of subscription to the Covenant, the English, both as the larger nation and as the less accustomed to Covenants, had remained considerably in arrear of the Scots; and, when the Scots actually did make their appearance in England, there was a sudden refreshing of the memory of the English Parliament on the subject, and a sudden exertion to make up the arrears. "The Scots are among us on the supposition that we have all taken the Covenant; and lo! we have not yet all taken it," was virtually the exclamation of the Parliament. Accordingly, that all might be brought in, that there might be no escape, and that there might remain to all time coming a vast register of the
