12. Through south entrance to South Passage; discovered by Sir John Willoughby; under centre of steps; outlet on lower face of steps. 13. Under step and parallel with wall at entrance to Sacred Enclosure (west) from No. 9 Enclosure; two similar drains on Acropolis. _Drains through an outer wall_:— 14. On north-west side of southern end of North-East Passage; through base of wall 4 ft. 6 in. wide; eastern exterior opening 8 in. high, 9 in. wide; covered with lintels; clear for 3 ft.; extended eastwards as an open drain 8 in. wide towards foot of steps of north entrance to the temple. 15.

[Illustration: EXTERIOR OF A DRAIN, ELLIPTICAL TEMPLE] [Illustration: MONOLITHS ON THE PLATFORM, ACROPOLIS (_Also see p. 315_)] DRAINS AT ACROPOLIS RUINS 16. In Western Temple, in divisional wall “A” (see plan and description); drain-hole passes 5 ft. from north to south; northern opening 9 in. high, 11 in. wide; impossible to state the fall owing to stones and dirt inside; fragments of cement lining were found here in 1891, 1892, and 1902. [The interior of this temple was on the north side of wall “A,” as well as on the south side of wall “D,” much higher than between these two walls, which form a small amphitheatre (Bent) within and at the west end of the larger amphitheatre formed by the main walls of the temple. This is obvious to anyone examining the interior. Practical builders have recently stated their belief that when the lower and western side of this smaller amphitheatre is cleared of débris drains will be found at the base of the main west wall, which, so far as discoveries have been made, is the widest ancient wall in Rhodesia. The whole interior of the temple, and the formation rock over which, but not upon which, it is built, slant at all points downwards to the foot of the inner face of the main wall.] 17. On west side of Upper Passage and leading from _Little Enclosure_; exterior opening 9 in. high, 6 in. wide; clear for 3 ft. inwards; interior opening covered with débris. 18. East corner of South Enclosure A; through south wall; 4 ft. long; fall outwards; covered with large slabs; exterior opening 12 in. high, 8 in. wide; interior opening dilapidated. 19. East entrance of Eastern Temple leading from temple to Gold Furnace Enclosure; under pavement of entrance; still 5 in. deep. DRAINS IN VALLEY OF RUINS 20.
