Returning to the nearer of the two cisterns on the north of the mosque, I went along the conduit, rising to the west, for a distance of 12 feet, beyond which I could not advance because of the soil in it. It runs exactly in the direction of the cistern, which is situated very near to the north-west corner of the net-work on the Plan[370]: this I afterwards endeavoured to enter, but found it filled with earth. The other opening, on the east side of the first-named cistern, is that of a descending conduit (about 3 feet wide and high), which I traversed for some distance, until I was eventually stopped by a number of obstacles; however, I ascertained clearly that it went towards the east.
The above observations are the results of three visits, in which the short time I was allowed to stay, the frequent summons to depart, coupled with not a few threats when I resisted, prevented me from making farther investigations; but there is nothing more to be found there of greater importance than the things I have mentioned.
On entering the cistern, excavated in the rock on the west of the Golden Gate, I found that it was 20 feet deep, and that on the west side was the mouth of the conduit, which I partially examined from the cistern north of the mosque _es-Sakharah_. I was able to pass along it for some distance on this side also, and found it to be 3-1/4 feet wide and 3 high. The only thing that now remained to be done was to find the conduit leading out of the cistern towards the east: and after a long search I had begun to despair, when a labourer, who was working at the south side of the chamber, told me that there were signs of an opening there; in a few minutes it was uncovered, and through it I entered into another cistern, whose floor was 4 feet below the level of the former; and on the east side of this was a conduit, 3-1/2 feet wide and 3 high, running towards the _Haram_ wall, which must have communicated with that the ruins of which I had found outside the east wall. I had thus completed a chain of evidence, which established the course of the conduit for blood, as laid down by me, at every point.
Marks of another opening appeared above the soil on the south side of the same chamber, but I had not time to uncover it, being recalled into the first cistern by the discovery of another passage on its north side; through this I entered a series of cisterns, on a level of 3-1/4 feet above the central. In the last of these, at the north end, was the entrance to a conduit (2-1/2 feet wide and high), which sloped upwards in the direction of the Pool of Bethesda. It was impossible to follow it up, but from its direction, level, and design (as I will presently shew), it must have corresponded with the opening (walled up) to which I called attention at the south-east corner of the above Pool.
