In the spring of 1890, a _firman_ having been obtained, Mr Flinders Petrie went to excavate at _Umm Lakis_ and _Ajlan_, the supposed sites of Lachish and Eglon, two of the five strongholds of the Amorites (Josh. x. 5). As soon as he arrived and could examine the ground, he saw, from his Egyptian experience, that the two sites named were only of Roman age and unimportant; while _Tell Hesy_ and _Nejileh_ in the same neighbourhood promised better results. _Tell Hesy_ is a mound of ruins 60 feet high and about 200 feet square, and one side of it has been washed away by the stream, so that a clear section is afforded from top to base. The generally early age of it was evident from the fact that nothing later than good Greek pottery was found at the top of it, while near the middle, and from that to three-quarters of the height, was found Phœnician ware, which is known in Egypt to date from 1100 B.C. The foundation seems to date from about 1500 B.C., agreeing nearly with the beginning of the Egyptian raids under Thothmes I. The actual remains of _Tell Hesy_ consist of a mound which is formed of successive towns, one on the ruins of another, and an enclosure taking in an area to the south and west of it. This enclosure is nearly a quarter of a mile across in each direction, and is bounded by a clay rampart still 7 feet high in parts, and in one place by a brick wall. This area of about 30 acres would suffice to take in a large quantity of cattle in case of a sudden invasion; and such was probably its purpose, as no buildings are found in it, and there is but little depth of soil. The city mound is about 200 feet square, and rests on natural ground 45 to 58 feet above the stream in the _wady_ below. The earliest town here was of great strength and importance, the lowest wall of all being 28 feet 8 inches thick, of clay bricks, unburnt; and over this are two successive patchings of later rebuilding, altogether 21 feet of height remaining. “Such massive work” (says Mr Petrie) “was certainly not that of the oppressed Israelites during the time of the Judges; it cannot be as late as the Kings, since the pottery of about 1100 B.C. is found above its level. It must, therefore, be the Amorite city, and agrees with the account that ‘the cities were walled and very great’ (Num. xiii. 28), ‘great and walled up to heaven’ (Deut. i. 28), and also with the sculptures of the conquests of Rameses II. at Karnak, where the Amorite cities are all massively fortified.” Mr Petrie feels little doubt that _Tell Hesy_ is Lachish and _Tell Nejileh_, 6 miles south of it, Eglon. There are no sites in the country around so suited to the importance of Lachish and Eglon as these two _tells_; they command the only springs and water-course which exist in the whole district, and it is certain that the positions must have been of first-rate importance from the time of the earliest settlements.
