While this statement might be true of many instances, there can be no doubt that public wells were dug even in those remote times. Indeed, the first mention made of a well, in the Book of Genesis, would indicate that its waters were free to all. Abraham's oldest servant, Eliezer, had been entrusted with the duty of selecting a wife for Abraham's son, Isaac. The servant journeyed to the ancient city of Nahor, and there "he made his camels to kneel down without the city by a well of water at the time of the evening that women go out to draw water." And he said: "Behold, I stand here by the well of water; and the daughters of the men of the city come out to draw water, and let it come to pass that the damsel to whom I shall say, Let down thy pitcher, I pray thee, that I may drink; and she shall say, Drink, and I will give thy camel drink also; Let the same be she that Thou hast appointed for thy servant, Isaac. And it came to pass that Rebekah came out, and the damsel was very fair to look upon, and she went down to the well and filled her pitcher, and the servant said, Let me I pray thee drink a little water of thy pitcher. And she said, Drink, my lord, and when she had done giving him drink, she said, I will draw water for thy camel also. And she hastened to empty her pitcher in the trough and ran again unto the well to draw water for all the camels." In Assyria and Persia from earliest times, water has been conveyed to towns from astonishing distances in open channels, and in Egypt, also in China, gigantic works for conveying water both for domestic use and for irrigation have been in existence from remote antiquity. In China, a knowledge of the art of well drilling has existed for centuries. Travelers speak of wells drilled by Chinese, centuries ago, to a depth of 1,500 feet. In the valley of the Nile are many famous wells. Joseph's Well[1] at Cairo, near the Pyramids, is perhaps the most famous of ancient wells. It is excavated in solid rock to a depth of 297 feet and consists of two stories or lifts. The upper shaft is 18 by 24 feet and 165 feet deep; the lower shaft is 9 by 15 feet and reaches to a further depth of 132 feet. Water is raised in two lifts by means of buckets on endless chains, those for the lower level being operated by mules in a chamber at the bottom of the upper shaft, to which access is had by means of a spiral stairway winding about the well.
