A very interesting discovery of an example of the use of the stone battle-axe, or celt, is thus described in a letter from Captain Denniston to Mr. Train. About the year 1809, Mr. M'Lean of Mark found it necessary, in the course of some improvements on his farm, to remove a large cairn on the Moor of Glenquicken, Kirkcudbrightshire, which popular tradition assigned as the tomb of some unknown Galwegian king, styled Aldus M'Galdus:--"When the cairn had been removed, the workmen came to a stone coffin of very rude workmanship, and on removing the lid, they found the skeleton of a man of uncommon size. The bones were in such a state of decomposition, that the ribs and vertebræ crumbled into dust on attempting to lift them. The remaining bones being more compact, were taken out, when it was discovered that one of the arms had been almost separated from the shoulder by the stroke of a stone axe, and that a fragment of the axe still remained in the bone. The axe had been of green stone, a species of stone never found in this part of Scotland. There were also found with this skeleton a ball of flint, about three inches in diameter, which was perfectly round and highly polished, and the head of an arrow, also of flint, but not a particle of any metallic substance."[163] Many of the most highly-finished celts and hatchets found in Scotland are made of the same green stone, which is susceptible of a beautiful polish. Other implements of this period are chisels of flint, nearly resembling those of Norway and Denmark. Several examples are in the Scottish Museum; and a curious instance of a perforated chisel, similar to those frequently found in Denmark, was turned up in 1841, in trenching a piece of ground near the Church of Lismore, Argyleshire. It is of the usual square form, measuring four inches long, and is described in the New Statistical Account as a stone needle.[164] Another and larger class of Scottish implements are cylindrical or oval perforated stones, of which no examples, I believe, have yet been found in Denmark or Sweden. The woodcut represents one of these implements, measuring 8¼ inches in length, found in a cist near North Berwick Abbey, East-Lothian, where many primitive remains have been discovered. It is flattened at the end where it is perforated, and is made of a very hard polished stone. Another was found in 1832, in the parish of Lumphanan, Aberdeenshire; and similar implements are occasionally mentioned among the contents of Scottish tumuli. In a cist, discovered under a barrow, in Kirkurd parish, Peeblesshire, there were various weapons of flint and stone, including one described as resembling the head of a halbert, another of a circular form, and the third of a cylindrical shape; in all probability a celt, a spherical flint or stone, and one of the implements now referred to, which may be conveniently designated as _flail-stones_.[165] On levelling a large tumulus a few years
