“Of the chapels, the largest is externally 20 feet in length,”[71] with small flat-headed windows--west end blank. Of the two other chapels, the largest is 19 feet 4 inches in length, with flat-topped window. The other (now removed), 17 feet 7 inches long externally, by 11 feet 6 inches wide; walls rudely built. The doorway, _with inclining jambs and flat head_, was in the east end; above, in gable, a flat-headed window, 14 inches long by 3 inches wide. [Illustration: FIG. 34.--Howmore. East Window.] KILBAR, BARRA. In a burying-ground, “three dilapidated chapels, resembling very much those at Howmore. The largest (Fig. 35) (supposed to be that of St. Barr), (1) is externally 42 feet in length; the end walls nearly away, the north and south walls nearly entire. The north side has a rude triangular-headed doorway (Fig. 36) enclosed in a semi-circular arch, and a triangular-headed window on its east. In the south wall there are three windows of the same form--two of them together near its east end, and one near the west end. Against the east end the altar remains almost entire. The next largest chapel (2) is externally 30 feet in length; it is divided by a dead wall into two unequal apartments, each having a flat-headed doorway on the south. The east end contains a flat-headed window 16 inches in length by 3½ inches wide, and there are windows of like kind in the side walls, the west one blank. Of the third and smallest chapel (4), externally 18 feet 3 inches in length, very little is left. At my first visit (July 1855) both ends were entire, the east one containing a small flat-topped window, the west one blank; now (July 1866) the only detail is a narrow window at the eastern extremity of the north wall, the head round, and formed of one stone.”[72] Another chapel at a little distance has been removed.

We shall now consider Mr. Muir’s descriptions of the rude hermitages which he discovered on some of the remotest rocks round the coast. THE CHAPEL OF ST. RONAN, NORTH RONA. The small solitary island of Rona lies about thirty-eight miles north-eastwards from the Butt of Lewis, and about the same distance from Cape Wrath. It is about one mile long and the same in width. Such an island, so far from land, formed a meet spot for the dwelling of an early Anchorite, and here is still preserved the Chapel of St. Ronan. The island was twice visited by Mr. Muir, who thus describes the chapel:--
