It will be readily understood, however, that these crude materials and primitive methods could not long keep pace with the steady march of progress. The peoples of the earth were increasing rapidly; they were advancing in the arts and sciences, and in the experiences that inspire thought, poetry, and philosophy; they had a heritage of knowledge to which they were constantly adding, while business transactions, together with other deeds worthy of record, had greatly multiplied. It was but natural that the materials which had once been entirely adequate should now be discarded as cumbersome and unfitted to the new conditions. The sands in the hour-glass were beginning to run golden; time was taking on a value unknown before. A deed of land written in clay and put away to bake might answer the purpose when real-estate transfers were infrequent and attended with much ceremony. A clay tablet might serve in a marriage proposal by a king who had the power to meet and vanquish all rivals, but terra-cotta was not suited either for the record of numerous and rapid business transactions or for the writing of books. The biography of one man, or a single treatise in philosophy, would have required a whole building, while a library of modern dimensions, as to the number of books, would probably have left little room in a city for the dwellings of its inhabitants. ♦Discovery of papyrus♦ What was to take the place of the old and cumbersome materials? Even at a very early date men were asking this question, and it was the good fortune of Egypt to be able to give answer. Along the marshy banks of the Nile grew a graceful water-plant, now almost extinct, which was peculiarly fitted to meet the new demands, as we shall see in the succeeding chapter. The discovery of its value led to an extensive industry, through which the land of the Pharaohs was enabled to take high rank in letters and learning, and, to maintain a position of wealth, dignity, power, and influence that otherwise would have been impossible, even in those remote days when printing was still many centuries beyond the thoughts or dreams of men.
