DRAINS IN ELLIPTICAL TEMPLE
DRAINS through main walls:—
1. At (352 ft.);[43] from Parallel Passage to exterior of temple; has a decided fall outwards; curves round at half through towards south; covered with large slabs; inner hole 1 in. below granite cement floor of passage, which slopes downwards from either side towards hole; interior opening 14 in. high, 9 in. wide; exterior opening, 12 in. high, 6 in. wide.
Between Nos. 1 and 2 drains the cement floor rises a few inches to a raised step-barrier 4 in. high, 3 ft. 10 in. broad, from which the flooring slopes down to No. 2 drain, thus forming catchment areas for each drain to clear off rain-water, so that each drain only had such an area to clear which its capacity would allow.
2. At (391 ft.); from Parallel Passage to exterior of temple; decided fall outwards; curves towards north-east; covered with large slabs; cement floor of passage level with floor of drain; interior opening 11 in. high, 11 in. wide; exterior opening 17 in. high, 11 in. wide.
[Facing this drain and on the west side of the passage is the drain (No. 7) from No. 14 Enclosure, described later.]
3. At (442 ft.); from Parallel Passage to Outer Parallel Passage; fairly straight; steep fall outwards; covered with large slabs; interior opening 12 in. high, 8 in. wide; exterior opening 15 in. high, 6 in. wide. [It was from this drain that fragments of cement lining were taken.]
4. At (476 ft.); from Parallel Passage to Outer Parallel Passage; partially obstructed at half-way through by stones and dirt; very decided fall outwards; curves slightly towards east; covered with large slabs; interior opening 11 in. high, 7 in. wide; exterior opening 10 in. high, 10 in. wide.
5. At (515 ft.); from Parallel Passage to Outer Parallel Passage; interior opening buried in débris supporting wall threatening to collapse; exterior opening 10 in. high, 6 in. wide; covered with large slabs; exterior portion shows decided fall outwards; clear for 8 ft., probably further.
