Cumberland was now hunting down the fugitives on all sides. He posted himself at Fort Augustus, which the insurgents had blown up before leaving it, and from that centre he sent out his myrmidons in every direction to hunt out the Highlanders, and shoot them down on the spot or bring them in for execution. Everywhere the unhappy clans were pursued by their hereditary enemies, the Whig clans, especially by the men of Argyllshire, and massacred with the most atrocious cruelty. They stripped their houses and then burned them down, drove away the cattle, and tracking the miserable families into dens and caves, smothered them with burning heather, or thus forced them to rush out upon their bayonets. In all these diabolical proceedings, the Duke of Cumberland and the brutal General Hawley were foremost. "After all," Cumberland (whose wicked work earned him the name of "The Butcher") wrote to the Duke of Newcastle from Fort Augustus, "I am sorry to leave this country in the condition it is in, for all the good that we have done has been a little blood-letting, which has only weakened the madness, but not at all cured it; and I tremble for fear[108] that this vile spot may still be the ruin of this island and our family."Sandy regretted his ruse presently, because he heard a boat and realized that he could not see who occupied it: furthermore, while his position would enable him to be hidden and to go along if Jeff took off, he would be helpless in case of an accident to the craft.
In 1720 Colin Maclaurin, the successor of James Gregory in the mathematical chair at Edinburgh, published his "Geometrical Organica," a treatise on curves; in 1742 his admirable treatise on Fluxions; and in 1748 his treatise on Algebra. Dr. Robert Simson, professor of mathematics at Glasgow, published a restoration of the "Loci" of Apollonius, and an English translation of Euclid, which continued down to a late period in use, both in Scotland and England. In 1717 James Stirling published a Latin treatise on lines of the third order, and another on Fluxions, called "Methodus Differentialis," in 1730. William Emerson, a mathematician and mechanist, wrote on fluxions, trigonometry, mechanics, navigation, algebra, optics, astronomy, geography, dialling, etc., but a considerable portion was only in part published during this period. Thomas Simpson, a weaver, of Market Bosworth, at the age of seven-and-twenty suddenly discovered himself as an extraordinary mathematician, and went on till his death, in 1761, publishing works on fluxions, the nature and laws of chance, on mixed mathematics, on the doctrine of annuities and reversions, on algebra, elementary geometry, trigonometry, etc. James Ferguson, also, the son of a day-labourer, in Banffshire, studied mathematics whilst tending sheep, and published a number of works on the phenomena of the harvest moon, astronomy, mechanics, hydrostatics,[154] pneumatics, and optics. Ferguson had a remarkably lucid and demonstrative style, both in writing and lecturing, and his example excited a keen spirit of inquiry amongst the working classes, so that he is said to have diffused the knowledge of physical science amongst the class from which he sprang more than any other man."I don't mind, and neither does Captain Landor." Her guardian had recently gotten his captaincy."I don't know anything whatever about it," he answered; "that is none of my affair. I should be surprised if he were, and I must say I am inclined to think he is not."
