The walls surrounding Mosul are very old. They were built, in the first instance, about 2000 years ago by a man named Marvan, one of the kings of a tribe called "Umayya." They were repaired 170 years ago by Hadji Hussein Pasha, one of the Abdul Jaleel family. They are now in many places fast falling into ruin, and are in great need of restoration. These walls are pierced by about twelve gates, which are shut at sunset or soon after. About five hours' journey from Mosul is the little village of Elkosh, believed by many to have been the birthplace of the prophet Nahum, and also the scene of his life-work and burial. This village, now inhabited by Chaldeans, is reverenced by Moslems and Christians alike, but more especially is it looked upon as a holy place by the Jews. There is a synagogue in which is supposed to lie the tomb of the prophet; to this the Jews flock for the yearly pilgrimage, having done so from time immemorial. Kalah Shurgat is another interesting place, situated two days' journey from Mosul. It consists of an old Assyrian ruin, said to be the remains of the ancient city of Asshur. The Germans have been excavating there for some years, and are doing it very thoroughly. The whole ground floor of the palace and temple are laid bare, and are in a wonderful state of preservation. One of the excavators pointed out to us the "bathroom" of the palace, running through which was a mono-rail, evidently having been constructed for the purpose of conveying water from the reservoir to the bath. This tram-line must have been one of the first ever invented! It was simply a groove cut in the marble floor, on which probably a one-wheeled trolley ran. The climate of Mosul is a very variable one, the summers being excessively hot and the winters cold. During the hot months all the inhabitants sleep at night on their roofs, starting about the 1st of June, and continuing to do so for five months, or till the first rains come. Many of the houses are provided with "sirdabs" or underground rooms, for use during the middle part of the day. The marble from which most of the houses are built retains the heat of the sun so long that they do not cool down in the evenings; on account of this, as the summer wears on, the houses become almost unbearable with accumulated heat. For this reason we generally try to go away somewhere for a month's holiday in August or September. There are no cool places near Mosul, and to find a suitable summer retreat it is necessary to go three or four days' journey. For two years we only went to a large house about three miles from Mosul, kindly lent us by a patient of my husband's. Here the heat was intense during the day, but the evenings were delightfully cool as a rule, for the river ran at the foot of the garden.
