Afterwards Amenj with 600 warriors had conveyed the produce of the goldmines from the canton of Hermopolis to the stronghold of Coptus. He had loved his canton; and all the works required for the house of the king he had carried out in his canton by his own arm, and had paid in the tribute. He had laboured, and the canton had been in full activity. He had not afflicted the children, or ill-treated the widows; he had not disturbed the fishermen, or hindered the herdsmen. Famine had never prevailed, because every plot had been planted. He had caused the inhabitants to live, had given gifts without regarding the great before the small.[158] The fragment of a seated colossus of Sesurtesen I., of black granite, is to be seen in the museum at Berlin; his colossus of red granite is at Tanis. A third statue of this king has been found at Abydus.[159] Amenemha II. and Sesurtesen II. carried on the campaigns of the first Sesurtesen in the south of Egypt. A monument in the valley of Hamamat exhibits battles with the Punt, _i.e._ with the tribes of the Arabians and the negroes.[160] Sesurtesen III., who succeeded Sesurtesen II., completed the subjugation of Lower Nubia. To protect the new border of the kingdom, he caused fortresses to be erected a little above the falls of the Wadi Halfa, at Semne and Kumne, about 250 miles south of Syene. A pillar discovered in this district has the following inscription:--"Southern border; erected in the eighth year, under the rule of his holiness King Sesurtesen III., who gives life for all eternity. No negro shall pass over it on his way, except the boats laden with the oxen, goats, and asses of the negroes."[161] The third Sesurtesen was followed by the third Amenemha (2221 to 2179 B.C.). Inscriptions in the Wadi Maghara, in the peninsula of Sinai, tell us that Amenemha III. caused the copper to be conveyed from the mines there by 734 soldiers, in the second year of his reign; and inscriptions in the valley of Hamamat show that the quarries there were frequently used by this king.[162] Near the fortifications of his predecessor, on the rocks of Semne and Kumne, are found numerous records of the height reached by the Nile in the reign of Amenemha III. Here we read--"Level of Hapi (the Nile) in the fourteenth, sixteenth, thirtieth years, &c., under his holiness King Amenemha III., who lives for ever." From these observations we find that the average height of the inundations at that time was more than twenty-four feet higher than at present; and the greatest height reached under Amenemha III. was twenty-seven feet above the greatest height of modern times.[163]
