Four men were tried at Perth for theft by the commissioners [Sidenote: 1701.] for securing the peace of the Highlands, and, being found guilty, were liable to the punishment of death. The Lords, however, were pleased to adjudge them to the lighter punishment of perpetual servitude, not in the plantations, as we have seen to be common, but at home, and the panels to be ‘at the court’s disposal.’ One of them, Alexander Steuart, they bestowed as a gift on Sir John Areskine of Alva, probably with a view to his being employed as a labourer in the silver-mine which Sir John about this time worked in a glen of the Ochils belonging to him.[297] Sir John was enjoined to fit a metal collar upon the man, bearing the following inscription: ‘Alex^r. Steuart, found guilty of death for theft, at Perth, the 5th of December 1701, and gifted by the justiciars as a perpetual servant to Sir John Areskine of Alva;’ and to remove him from prison in the course of the ensuing week.[298] The reality of this strange proceeding has been brought home to us in a surprising manner, for the collar, with this inscription, was many years ago dredged up in the Firth of Forth, in the bosom of which it is surmised that the poor man found a sad refuge from the pains of slavery. As a curious memorial of past things, it is now preserved in our National Museum of Antiquities. The reader will perhaps be surprised to hear of a silver-mine in the Ochils, and it may therefore be proper, before saying anything more, that we hear what has been put on record on this subject. ‘In the parish of Alva, a very valuable mine of silver was discovered about the commencement of the last century[299] by Sir James [John] Erskine of Alva, in the glen or ravine which separates the _Middle-hill_ from the _Wood-hill_. It made its first appearance in small strings of silver ore, which, being followed, led to a large mass of that metal. A part of this had the appearance of malleable silver, and was found on trial to be so rich as to produce twelve ounces of silver from fourteen ounces of ore. Not more than £50 had been expended when this valuable discovery was made. For the space of thirteen or fourteen weeks, it is credibly affirmed that the proprietor obtained ore from this mine to the value of £4000 per week. When this mass was exhausted, the silver ore began to appear in smaller quantities; [Sidenote: 1701.] symptoms of lead and other metals presented themselves, and the search was for the present abandoned.’[300] It is related that Sir John, walking with a friend over his estate, pointed out a great hole, and remarked: ‘Out of that hole I took fifty thousand pounds.’ Then presently, walking on, he came to another excavation, and, continued he: ‘I put it all into _that_ hole.’
