pure water to the Nile valley by canal. It seems that the precise date when the encroachments upon the supply and extension of cultivation in the northern basin localised its benefits may be fixed between the visits of Mutianus and Pliny.

This requires more elaborate argument and illustration, but see the folios passim, and of Rome, 1478, Venice, 1511, and the text, Wilberg, 1830, pp. 279, 282.

' eroded,' as the ancient authors uniformly stated. The Xous of Herodotus is the equivalent of "un terrain si peu compacte et aussi friable." L. de B. (1873) p. 55. (36).

The "canal of Joseph" is a misconception. (37). The depth of the lake was 'shown by two pyramids, somewhere near the middle, in its deepest part.' The stones at Bihamu are not pyramids, they stand near the limit of the highest plateau, and may be of Roman date. M Jomard objected that a structure would not prove the depth of an excavation. He failed to consider with the statement of Herodotus the succinct account of Diodorus : “Ο δ' οὖν βασιλεὺς ὀρύττων ταύτην κατέλιπεν ἐν μέση τόπον, ἐν ᾧ τάφον ὠκοδόμησε καὶ δύο πυραμίδας, τὴν μὲν ἑαυτῶν τὴν δέ τῆς γυναικός, σταδιαίας τὸ ὕψος. As in the Latomia del Paradiso of Syracuse, in modern French quarries, and in the East, a squared mass of the natural rock was left standing to show the amount of stone removed. As the hollow in this case was filled with water, two piles above marked the depth beneath. Against (i) them were colossal statues. On the well-established Eastern principle, si monumentum quæris,' the king also constructed a tomb in the noble challenge which he offered to all potentates from |
