It will be agreed by all those who know Egypt that a great dam was necessary, and it will be admitted that no reach of the Nile below Wady Halfa could be converted into a reservoir with so little detriment to _modern_ interests as that of Lower Nubia. Here there were very few cultivated fields to be inundated and a very small number of people to be dislodged. There were, however, these important ruins which would be flooded by such a reservoir, and the engineers therefore made a most serious attempt to find some other site for the building. A careful study of the Nile valley showed that the present site of the dam was the only spot at which a building of this kind could be set up without immensely increasing the cost of erection and greatly adding to the general difficulties and the possible dangers of the undertaking. The engineers had, therefore, to ask themselves whether the damage to the temples weighed against these considerations, whether it was right or not to expend the extra sum from the taxes. The answer was plain enough. They were of opinion that the temples would not be appreciably damaged by their flooding. They argued, very justly, that the buildings would be under water for only five months in each year, and for seven months the ruins would appear to be precisely as they always had been. It was not necessary, then, to state the loss of money and the added inconveniences on the one hand against the total loss of the temples on the other. It was simply needful to ask whether the temporary and apparently harmless inundation of the ruins each year was worth avoiding at the cost of several millions of precious Government money; and, looking at it purely from an administrative point of view, remembering that public money had to be economised and inextravagantly dealt with, I do not see that the answer given was in any way outrageous. Philae and the other temples were not to be harmed: they were but to be closed to the public, so to speak, for the winter months. [Illustration: PL. XXV.
