The present structure is evidently, from its style, of a late date. The construction of the vaulting, with its low arches at the crossing, and pointed vault covered with stone roof over the choir; the plain outline of the tower and walls, without buttress or break of any kind; and the square lintelled windows, are all indications of a date about the end of the fifteenth or beginning of the sixteenth century.

ST. BOTHAN’S COLLEGIATE CHURCH, Yester, Haddingtonshire.

A structure partly old and partly new, which stands beside the mansion house of Yester, the seat of the Marquis of Tweeddale. Its position is very fine, situated as it is by the side of a clear flowing stream, and surrounded by splendidly wooded braes.

The construction of the old part of the building, as seen in the interior, is very massive and, considering its small dimensions, imposing, and it remains in a good state of preservation.

The edifice (Fig. [1232]) consists of a choir and transepts. Of the nave hardly anything exists, and there is nothing to indicate that it ever was built. The present west wall is modern, probably of this century. The choir measures, internally, 13 feet from east to west by 18 feet 6 inches wide. The total length across the transepts is about 53 feet 6 inches from north to south by 13 feet in width, all inside dimensions. It will be observed that the nave and choir are not quite in the same line.

The crossing (Fig. [1233]) is covered with a pointed barrel vault in continuation of that of the choir, and is supported at the springing by very massive low round arches, which span the entrance to each transept. The choir vault is separated from the crossing by a late arch, supported on pillasters of a Renaissance form, and it has been emphasised by having ribs on the surface of the vault, as shown on the Plan by dotted lines, but these do not now exist. The transepts are also vaulted with plain pointed vaults carried to a considerable height, but cut off from the crossing, as at Ladykirk and Queensferry, by the arches introduced to carry the central vault of the crossing. As the church was without buttresses, the walls are of considerable thickness (not less than 4 feet) in order to resist the pressure of the arches. In the north wall of the south transept, near the apex of the roof (see Fig. [1233]), there is a small door, now built up, which probably gave access to a small chamber in the haunch of the vault over the crossing.
