crossing are of equal size--an unusual arrangement, as the nave is generally the longest division of the church. This was part of the original design, as the western doorway is one of the most prominently Norman portions of the edifice, and no satisfactory explanation has yet been given of the shortness of the Kelso nave. The upper portion of the west front has been in the transitional style, and the Norman arcading, which runs round the interior of the nave, was continued across the west end. The nave, north and south transepts, contain each four stories in height, consisting of an interlacing arcade of Norman work in the interior of the ground level, and three stories of windows above. The upper arcades of the choir do not extend round the nave and transepts, except in a portion of the south transept. The windows in the different stories have all round arches, both inside and outside, and the exterior is marked at each angle by broad and shallow Norman buttresses, with nook shafts in the angles, and an interlacing arcade round the lower story, both internally and externally. In the facades of the west end and north transept the windows of the different stories have been grouped so as to form distinct designs. "In the west end, over the great west doorway, there has been an arrangement of tall windows of apparently lancet form, having on either side an interlacing arcade of round arches, supported on tall, bended shafts. This is now, unfortunately, greatly destroyed. Above the arcade there runs a horizontal flat cornice, enriched with several rows of carved ornaments, and this was surmounted by a large opening of quatrefoil shape, surrounded with numerous mouldings and enrichments. The angle buttresses have been crowned with octagonal turrets."[424] The north wall of the north transept has a fine transitional door-piece, occupying the two lower stories. The next two stories have each two windows, separated by a small buttress, and the upper story has three arches in the interior. "Above these stories is a small circular window with a curious saving arch over it, and the whole is crowned with a top story, containing three round-headed openings, and a gable with a small circular aperture. The buttresses at the angles are crowned with circular turrets, which have been finished with a projecting parapet, the corbels for carrying which still survive. The upper part of the gable shows signs of having been altered."[425]
