[28] Mr. R. Brown, jun., F.S.A., in his _Earlier History of Barton-on-Humber_, vol. i. p. 12, supposes that this road kept to the heights, leaving Yarborough to the east, and ended at South Ferriby. But if the Barton earthwork be really Roman, as Yarborough unquestionably is, a road connecting both with Caistor seems not unlikely. [29] Geoffrey gives its British name as “Caer Corrie”—strangely corrupted by Camden into “Caer Egarry.” The name suggests a connection with the Coritani; but it occurs only in this mass of fantastic legend. [30] E. A. Freeman, _English Towns and Districts_, 1883, pp. 210, 211. [31] The Church of St. Peter “ad Fontem,” which Picot, son of Coleswegen, gave to St. Mary’s Abbey at York (see notice of grant _ap._ Dugdale, _Mon. Angl._, ed. Caley, &c., 1846, vol. iii. p. 549), was in the eastern suburb of the city. Here, then, we must place that “wasta terra” which King William gave to Coleswegen, and the two churches which Coleswegen endowed there (_Domesday Book_, Lincolnshire _fac-simile_, f. 2_b_). [32] See plan of Barton-on-Humber and conjectural elevation of the original building, _ap._ Baldwin Brown, _Arts in Early England_, 1903, vol. ii. p. 210. An account of Broughton, with views of the tower arch, follows, pp. 211 _sqq._ [33] The wooden stair at Brigstock has been replaced by a ladder, but the holes for the stair-logs remain in the inner wall of the turret. The stone stair at Broughton has been supposed to be an afterthought of the builders, but the present writer is very doubtful about this. [34] An illustration and description of this tower will be found in _Assoc. Archit. Societies’ Reports_, vol. xxix., 1907, p. 70, at the end of an article in which the present writer has collected the results of his observation of towers in the neighbourhood of Grimsby and Caistor. [35] The present belfry stage of the tower is of the fifteenth century, and is built on piers and arches placed against the inner face of the older tower walls. For plan of the older tower, see Baldwin Brown, _op. cit._, ii. 240. [36] Twenty-six is the exact number of towers which may be said to be unquestionable members of the group. But the number may be raised by the inclusion of a few more possible examples. [37] The roof-line, visible on the eastern wall of the tower, is that of the mediæval church before the addition of the clerestory. [38] Hough-on-the-Hill, as noted later, is the only example in which the details of the quoining really approximate to those at Barton; but at Hough there is no strip-work.
