The Master never held up his head again, "and now, as formerly, by his affable and obliging carriage, he had procured the epithet of the Good Master of Somerville, so from henceforth he might have been called the Sad and Sorrowful Brother; for it was observed from the very moment of that unhappy accident, until his death, which fell out about three years thereafter, he never enjoyed a comfortable hour, but was still sad and melancholy."

In January 1592, the Master died from the effects of a fever, acting on a low and broken spirit; and with him perished all the hope and expectation of the house of Cowthally. Well might their ancient retainer, as the corpse passed the outer gate, smite on his breast and cry aloud, "This day the head is clean taken off the house of Cowthally, as you would strike off the head of a sybba!"[27]

The extravagance of Gilbert, the succeeding Lord Somerville, dissipated all the family property in Lanarkshire; and the lands of Gilmerton and the Drum remained the sole possession of a family which was now so poor that the head of it dropped his ancient title and held it in abeyance.

The house of the Drum, which had been burnt soon after its completion, then rebuilt in greater splendour, and again burnt in 1629, was left in a ruinous state till 1730-40, when James, the thirteenth Lord Somerville, pulled it down, and built an entirely new house, from Adam's designs. This Lord Somerville revived the title and restored the fortunes of the family. He was assisted in this by his own wise and prudent conduct, and by the advantages he gained from two rich marriages. He was an ardent Hanoverian; therefore, when in 1745 Prince Charles was holding his court at Holyrood, with a strong army in possession of the capital, Lord Somerville felt his position at the Drum, only four miles from Edinburgh, was an unpleasant one.

One night, when the family were at supper, word was brought in that the Highlanders were seen advancing up the avenue. All were in consternation. The plate was instantly thrown out of the window into the grass, which luckily was high; and Lady Somerville entrusted a casket of diamonds to her step-daughter, Anne (afterwards Mrs. Burges), with directions to conceal them. Miss Somerville ran out of the house into the deer-park, and, making a hole at the root of a tree, buried the diamonds, and crept back to the house unperceived. In the meantime, Lord and Lady Somerville had locked themselves into a closet in one of the garrets, and effectually concealed themselves. The Highlanders, about forty in number, broke into the house, and, not finding Lord Somerville, contented themselves with feasting on whatever they could get in the kitchen and cellars, and then carried off everything movable of any value. By this time a servant had escaped to the village of Gilmerton, and roused the inhabitants, who sallied forth to Lord Somerville's rescue. Half-way between the village and the house they met the Highlanders. A bloody conflict ensued, in which three of the former and five of the latter were killed. It ended in the Highlanders relinquishing their booty and beating a retreat. Next day the Prince, with his usual generosity, and out of respect for Lord Somerville's high character, sent an officer's guard to protect him.

Eight months later, when the royal cause was defeated and lost, Lady Somerville bethought herself of her diamonds. Her step-daughter readily undertook to restore them, but when she went into the park, she found it by no means so easy a task as she expected. There were hundreds of trees growing there, and in the hurry and agitation of the moment, she had not observed exactly beneath which she had hidden them. She was afraid to confide her difficulties to her father, and did not think it advisable to trust in any of the servants. Finally she told her brother, and night after night the two went into the wood and hunted for the lost diamonds. At last, after much anxiety, they came upon them lying safely in the earth, the casket having completely mouldered away.[28]

In the year 1800, John, fifteenth Lord Somerville, sold the Drum to Mr. More Nisbett, to whose family it now belongs. The house was originally intended by Adams to have another wing; but the death of James, Lord Somerville, putting an end to the works, the eastern wing was never built.

We now leave the Drum on our right and proceed northwards on the main road leading from Newbattle to Edinburgh. After passing through the village of Gilmerton, we descend a long hill, and, looking over the wall to our left, perceive the venerable sycamores and chestnuts, and the high holly hedges, which hide the house of Moredun.

This place, which is of great antiquity, was originally known as Goodtrees,—corrupted by the vulgar to Gutters,—and formed part of the great Somerville property. During the minority of John, fifth Lord Somerville, these lands were alienated by his uncle and guardian, Sir John of Quathquan, who contrived to get a fresh grant from James IV., and had them settled on himself and his heirs, the Cambusnethan branch of the family. The story of how they were recovered is a curious instance of how frequently designing persons outwit themselves.
