NOTES ON THE STONE MONUMENTS IN THE ISLE OF MAN. Historic Period is represented by structural and monumental remains, dating from the introduction of Christianity to the earlier Celtic inhabitants in the sixth or end of the fifth century. Among these remains are a number of inscribed stones and incised and carved Cross-slabs; and the ruins and foundations of early Keeils, Cells, or Churches. Keeil Woirrey, in Corna Valley, Maughold, measures (inside) 12 feet by 9 feet, the walls over 3 feet thick and 4 feet high, but 2 feet high outside. The floor shows signs of pavement. The doorway is at the S.W. corner. Among the stones of the ruined wall was one bearing a very simple form of cross, which judging from its appearance may be earlier than the seventh century . Near this keeil, an interesting discovery was made some years ago by the Rev. S. N. Harrison, who came across a rough unhewn slate slab, used at a well beside the little stream below, which bears an inscription in the ordinary Manks runes with a formula differing from any previously met with, namely Krist, Malaki, and Patrick (and) Adamnan. Unal (O'Neal's) shepherd Juan carved this in Kurna dale. Probably it was cut in the 13th century by Juan of the sheep, while watching his master's flock in the valley, and he was thus distinguished from another, namely, " Juan the Priest," who about the same time carved runes on a somewhat similar rough slab at the parish church. On Balla-fayle, in the same parish, overlooking the sea at the south end of Port Mooar, are the remains of Keeil Casherick, or Keeil Chiggyrt, as it is also called. In the surrounding burial ground was found a wheel-headed cross-slab, now to be seen at the parish church. Sculptured on one face is an equal-limbed cross with knot-work decoration, below which is a, human figure probably intended for Christ. .On Ballingan, Marown, are the ruins of a keeil and burial ground. The enclosure is 108 feet long by 63 feet broad. In the south-east part lies the keeil, its walls about four feet high by three thick. In the west end has been a window; the doorway is in the south-east angle, built of rubble stone work with two monolithic jambs inclining. The font measures 1 foot 11 inches long by 102 inches broad. .One of the most interesting of these early keeils is that known as St. Luke's (St. Luac), on the lonely shore at the western foot of Cronk-ny-Irree-Laa. It is traditionally known as the Church and Cemetery of the Danish Kings. .Burial, in the ancient cemeteries round these keeils, was in " lintel-graves," about 3ft. deep and 2ft. wide, dug east and west, and lined with small flagstones to the height of 15 inches. The corpse was wrapt in a mort-cloth, and the top closed in by similar, sometimes rather larger flags. No implements or relics have been found in any of these graves. Three or four such graves may be seen in section at Kilkellane, Lonan, where the electric tram road has cut through a burial ground. Sometimes such early cemeteries are found where now there is no trace or tradition remaining of the keeil which must once have stood there, as at the Flagstaff above Glen Wyllin, Michael, and by the old Castletown road from Foxdale, on Barrule Farm. Occasionally these lintel-graves are met with even in the Parish Churchyards, having continued in use until the commencement of the seventeenth century. It is in connection with these old keeils and the later Parish Churches, some of which are on the ancient sites, that those carved stone monuments have been found in which the Isle of Man is so peculiarly rich.
