The mound of Kalah Sherghat having been very imperfectly examined during my former residence in Assyria[96], I had made arrangements to return to the ruins. All my preparations were complete by the 22d of February, and I floated down the Tigris on a raft laden with provisions and tools necessary for at least a month's residence and work in the desert. I had expected to find Mohammed Seyyid, one of my Jebour Sheikhs, with a party of the Ajel, his own particular tribe, ready to accompany me. The Bedouins, however, were moving to the north, and their horsemen had already been seen in the neighbourhood of Kalah Sherghat. Nothing would consequently induce the Ajel, who were not on the best terms with the Shammar Arabs, to leave their tents, and, after much useless discussion, I was obliged to give up the journey. Awad, with a party of Jehesh, had been for nearly six weeks exploring the mounds in the plain of Shomamok, the country of the Tai Arabs, and had sent to tell me that he had found remains of buildings, vases, and inscribed bricks. I determined, therefore, to spend a few days in inspecting his excavations, and in carefully examining those ruins which I had only hastily visited on my previous journey. I accordingly started from Nimroud on the 2d of March, accompanied by Hormuzd, the doctor, and Mr. Rolland. We descended the Tigris to its junction with the Zab, whose waters, swollen by the melting of the snows in the Kurdish mountains, were no longer fordable. Near the confluence of the streams, and on the southern bank of the Zab, is the lofty mound of Keshaf, where are the remains of a deserted fort, commanding the two rivers. It was garrisoned a few years ago by an officer and a company of irregular troops from Baghdad, who were able from this stronghold to check the inroads of the Bedouins, as well as of the Tai and other tribes, who plundered the Mosul villages. Since it has been abandoned, the country has again been exposed to the incursions of these marauders, who now cross the rivers unmolested, and lay waste the cultivated districts. The tents of the Howar were about five miles from Keshaf. Since my last visit, he had become once more the acknowledged chief of the Tai. Faras had, however, withdrawn from his rival, and, followed by his own adherents, had moved to the banks of the Lesser Zab. The Shammar Bedouins, encouraged by the division in the tribe, had, only three days before our visit, crossed the Tigris and fallen suddenly upon the Kochers, or Kurdish wanderers, of the Herki clans. These nomades descend annually from the highest mountain regions to winter in the rich meadows of Shomamok. They pay a small tribute to the Tai for permission to pasture their flocks, and for protection against the desert Arabs. The Howar was consequently bound to defend them; but in endeavoring to do so, had been beaten with the loss of forty of their finest mares.
