But there are two Niles. One runs through the continent of Africa, and empties into the Mediterranean Sea. Another begins in the very earliest dawn of history, and runs through the human story of thought, feeling, and life. Along the banks of this Nile, in history, we see how human life was developed; all human life beginning away back there, so far back we cannot count it by years; when man made knives of flints and hatchets of stone. And then, because the Nile gently overflowed its banks two or more times a year, leaving after each freshet a soft layer of fertile mud on either side, primitive man began to plant his seed in this field plowed by a river, and to raise his millet, and peas, and beans, and some kind of wheat and corn. He was able to feed his cattle, and to raise chickens and geese along the banks of this river, which was only a green ribbon, from six to ten miles wide, four or five hundred miles long. On this green ribbon a great civilization, so great and so wonderful that only very learned men can understand how wonderful and how great it was, grew up. Find out something about the pyramids. Look up pictures of the ruins of the Temple of Karnak; and that great stone image, carved out of a hill, higher than a five-story building, with a head so large that if a man stood on the top of one ear he could hardly reach the top of the head with his outstretched hand. The Greeks called this great stone image, with the body of a lion and the head of a man, a sphinx; but the Egyptians called it the "Hor-em-khoo," the "Horus-on-the-horizon;" and Horus was the god-child they most loved, the child of Osiris, the great sun-divinity, and of Isis, the beautiful mother of heaven. All this civilization along the Nile would have been impossible had it not been for the Nile. The great stones that went into the pyramids were floated down the river. Soldiers and workingmen were transported on the river. The fields were made fertile by the river, and the leisure and the wealth that were made possible by the fertile fields on the river's bank gave men time to think and to feel, to invent the beautiful picture writings, to cut out the great tomb temples, and to think the great thoughts of religion, God-thoughts, love-thoughts, and duty-thoughts.
