The mound _H_ describes about two-thirds of a circle. Its base at the south is 6 m.--20 ft.--from E. to W.; its diameter, 6.85 m.--23 ft; its actual height, about 1.5 m.--5 ft. It is conical, and appears to be a round heap of earth and rocks encased with neat and judicious piling of well-selected stones. This naturally gave the stone-work a slanting surface; the higher it reaches, however, the more it becomes vertical, until at last it juts out above the surface of the mound like a circular breastwork, or a hollow round tower on a conical base. I refer to Pl. X. for an excellent view of its vertical aspect and structure. This mound, or tower, while it commands an extensive view to the west, north, and even north-east, is also the most northerly "spur" of the western wing of the great house _A_. This wing extends in an unbroken length of 62 m.--203 ft.--from the base line of _H_ to the entrance _N_, and is divided into 3 transverse sections, all connected, and all having 3 longitudinal rows of rooms or cells. The width of each cell is the same in every section, to wit, from E. to W. 2.58 m., 2.58 m., and 3.22 m.--8 ft. 6 in., 8 ft. 6 in., and 10 ft. 6 in., respectively. Section _k l l m_ has 3 × 5 apartments; in length from N. to S., 2.51 m., 3.86 m., 2.35 m., 3.71 m., and 3.72 m.--8 ft., 13 ft., 8 ft., 12 ft., and 12 ft. It was therefore 16.15 m. × 8.38 m.--53 ft. × 27 ft. Probably all the ground-floor cells were on the same level. Section _l l h h_ has 3 × 12 apartments, each 2.53 m.--8 ft.--long. Consequently, it was a rectangle of 30.36 m. x 8.38 m.--100 ft. × 27 ft. The eastern row of chambers was on the slope. Section _h h N_ 3 × 4 long, respectively 2.77 m.--9 ft. each, therefore 10.98 m. × 8.38 m.--36 ft. × 27 ft. There were two eastern rows on the slope.
