Figure 44.—Unorthodox arrangement of arches:

the lower series of three arches below the middle arch (1) rested in the normal way on the curb plate (2). Above the middle arch, the curb (3) was laid horizontally with its ends touching the end rafters (4). It resembled an upper curb plate, not only as regards direction, but also because 2 arches (5 and 6) had their ends resting on it. The uppermost fau tali 'aso (7) was normal in position. Two pieces like the lower limbs of an incomplete arch (8) filled the space between the end rafters and the middle arch. It was not an improvement in appearance, but it is figured, as new inventions are discovered through such departures from the normal.
