 crossing (see Fig. 1216), where it is round and at right angles to that of the choir, from which it is cut off and separated by the tower arch. The springing of the tower arches is kept below that of the vault over the crossing, as is usually done, in similar circumstances, in late structures, so as to avoid the difficulties of groined vaulting. The roof covering of the choir is of large overlapping stones, wrought after the manner so often found in the castles and churches of the fifteenth century. A wide gutter runs along the eaves (Fig. 1218), from which the water escapes by numerous gargoyles.

In the opposite wall a door leading to the cloisters has the reverse arrangement, being round-arched in the inside and lintelled on the exterior, where, on its west jamb, there is a Maltese cross. A similar cross is visible on the west side of the transept near the south end. There was a door into the cloisters from the crossing (see Fig. 1215) and another existed from the nave.

The windows of the choir (Figs. 1222 and 1223) are all pointed, and filled with the simplest tracery. Those of the nave and transept (Figs. 1224 and 1225) have square heads formed of straight arches, as shown in the detailed drawings. These windows have cusped tracery, which, in the nave, remained entire to the last, while that of the transept window
