An old Greek historian once said, "Egypt is the gift of the Nile," and it is perfectly true. We have seen how the great river made the country to begin with, cutting out the narrow valley through the hills, and building up the flat plain of the Delta. But the Nile has not only made the country; it keeps it alive. You know that Egypt has always been one of the most fertile lands in the world. Almost anything will grow there, and it produces wonderful crops of corn and vegetables, and, nowadays, of cotton. It was the same in old days. When Rome was the capital of the world, she used to get most of the corn to feed her hungry thousands from Egypt by the famous Alexandrian corn-ships; and you remember how, in the Bible story, Joseph's brethren came down from Palestine because, though there was famine there, there was "corn in Egypt." And yet Egypt is a land where rain is almost unknown. Sometimes there will come a heavy thunder-shower; but for month after month, year in and year out, there may be no rain at all. How can a rainless country grow anything? The secret is the Nile. Every year, when the rains fall in the great lake-basin of Central Africa, from which one branch of the great river comes, and on the Abyssinian hills, where the other branch rises, the Nile comes down in flood. All the lower lands are covered, and a fresh deposit of Nile mud is left upon them; and, though the river does not rise to the higher grounds, the water is led into big canals, and these, again, are divided up into little ones, till it circulates through the whole land, as the blood circulates through your arteries and veins. This keeps the land fertile, and makes up for the lack of rain. Apart from its wonderful river, the country itself has no very striking features. It is rather a monotonous land--a long ribbon of green running through a great waste of yellow desert and barren hills. But the great charm that draws people's minds to Egypt, and gives the old land a never-failing interest, is its great story of the past, and all the relics of that story which are still to be seen.
