division between chancel and nave. The western bay of the south aisle was set out about the same time, and there was, no doubt, an intention of proceeding with the rest on the same lines as in the north aisle. There can also be little doubt that the builders intended to take down the old arcades, and build new arcades, with spacing corresponding to that of their aisles, and to lengthen the chancel eastwards, while bringing its western portion into the nave. The tower and north aisle were built on the intended scale; and, when the tower had risen to a certain height, the ambition of the builders was fired to add to it an extra stage, hitherto uncontemplated, below the spire with which it was to be crowned. This project of giving their church a tower and stone spire, which remained, for many years, the loftiest in England, evidently curtailed the full accomplishment of their earlier plan. The columns of the old arcades were kept, and the tower was connected by arcades of two bays with the angles of the west wall of the old church; while an arch was pierced through the north wall of the chancel, to give access to the east bay of the new aisle. The new arches were pointed: in order to match them, the older round-headed arches were taken down, and pointed arches built, which cut into and blocked the clerestory windows. This change was made with great economy of material, the springing stones of some of the old arches being kept to afford footing for the new. When the south aisle was seriously begun, about 1300, similar economy was shown. Four bays, in addition to the western bay, were spaced out, without regard to the plan of the north aisle. The fourth bay from the west was covered by a porch, smaller than that on the north side; and the east wall of the aisle was probably built on a line with the division between nave and chancel. Half a century later, the east wall was taken down, and the south aisle was extended to the full length of the chancel; but this later development was not contemplated by the thirteenth century builders. These hesitations and changes, consequent upon the expense entailed by the north aisle and by the alteration in the elevation of the tower and spire, make Grantham second to no English church in interest.
