Today the traveller on the Nile enters a wonderland at whose gates rise the colossal pyramids of which he has had visions perhaps from earliest childhood.

There is but little room for doubt that Egypt led the way in the creation of the earliest known group of civilizations which arose on both sides of the land bridge between Africa and Eurasia in the fourth millennium B.C.

It is this conception of the unity of the human career which is perhaps the greatest achievement of historical study, since it gained a place analogous to that of natural science.

By 3000 B.C. the art of Egypt was so ripe and so far advanced that it is surprising to find any student of early culture proposing that the crude contemporary art of the early Babylonians is the product of a civilization earlier than that of the Nile.

In any case, in so far as our knowledge of the universe carries us, the advent of civilization for the first time on our globe represents the highest ascent of the life processes to which evolution had anywhere attained.

But it is obvious that our fathers, whose efforts have planted these great and prosperous cities along the once lonely trails of our own broad land, received all the fundamentals of civilization as a heritage from their European ancestors.
