In the foundation, on the south side of Mustafa Bey's house, at a depth of 22 feet, a quantity of water had appeared during the night and filled the hole. The master-mason and the owner, the sole architects, believed that it had filtered through from some cistern in the neighbourhood, and therefore set to work to bale it out. When this was done they were very much surprised to see that a thin stream of water, coming from the north-west, continued to fill the place; they therefore deepened the excavation a little, and widened the opening, but they were unable to account for the abundance of the water, which hindered their work. On arriving at the spot I suggested excavating, but the fear of the increased expenditure kept them from agreeing to this; so that, under the circumstances, I had no other means of ascertaining anything, than examining a number of cisterns which were in the neighbourhood; and after tasting the water in them, and comparing it with that in the hole, I found that the latter was of the same quality as that in the _Hammam es-Shefa_ and the Fountain of the Virgin; and then I began to believe that it came from a spring. The owner of the place consented to suspend the works in this part for eight days, but I could not prevail on him to permit me to make any excavation near the place on the north-west; and during this time the water flowed through a canal which I had constructed for it. After building two massive piers on each side of the stream and turning a strong arch over it, the works proceeded; so that the stream ran away to the south, without our having found a solution of the problem; but I have no doubt that careful investigation would have revealed the spring-head close by on the north-west. The discovery of June 12th, and the identity in taste and colour between the water then found and that of which I have spoken, caused me to examine the part of the city between the two points; and though the Arab houses in this district caused many difficulties, I succeeded in ascertaining that in this direction there were cisterns, into which water found its way, similar to that at the spring, and consequently not fit for all the purposes of life. From this I concluded that the two springs must be connected, and the upper supply the lower. But still there was the question, what became of all the water which issued from the spring at the Convent of the Daughters of Sion? At the first moment I was disposed to think that it flowed into the subterranean gallery, in the direction of the north-west corner of the _Haram es-Sherîf_; but my observations have brought me to the conclusion that it goes into the well of the _Hammam es-Shefa_, as I will now shew.
