the place of a hundred musketeers in battle. However, there is no evidence that he actually produced any of these devices. In 1627, however, he seems to have been home for a short time, as, in that year, he appears in the entirely new character of the holder of a patent for the construction of military machines, entitled "Litera Magistri Gulielmi Drummond de Fabrica Machinarum Militarium, Anno 1627". In 1630 Drummond again began to reside permanently at Hawthornden, and in 1632 he married Elizabeth Logan, by whom he had five sons and four daughters. In 1633 Charles made his coronation-visit to Scotland; and Drummond's pen was employed in writing congratulatory speeches and verses. He was involved in organising the King's triumphal procession through Edinburgh. As Drummond preferred High Church Episcopalianism to Presbyterianism, and was an extremely loyal subject, he supported King Charles's policy of spreading Laudianism, though he protested against some of the methods employed to enforce it. When Lord Balmerino was put on trial for the capital offense of retaining in his possession a petition regarded as a libel against the King, Drummond in an energetic "Letter" (1635) urged the injustice and folly of the proceedings. About this time a claim by the earl of Menteith to the earldom of Strathearn, which was based on the assertion that King Robert III, husband of Annabella Drummond, was illegitimate, roused the poet's pride of blood and prompted him to prepare an historical defence of his house. Partly to please his kinsman the earl of Perth, and partly to satisfy his own curiosity, the poet made researches in the genealogy of the family. This investigation was the real secret of Drummond's interest in Scottish history; and so we find that he now began his History of Scotland during the Reigns of the Five Jameses, a work which did not appear till 1655, and is remarkable only for its good literary style. His next work was called forth by the king's enforced submission to the opposition of his Scottish subjects. It is entitled Irene: or a Remonstrance for Concord, Amity, and Love amongst His Majesty's Subjects (1638), and embodies Drummond's political creed of submission to authority as the only logical refuge from democracy, which he hated. In 1639 Drummond grudgingly signed the Covenant solely for self-protection, but was uneasy under the burden, as several political squibs by him testify. In 1643 he published
