This stream of life has grown in force and volume with the passage of ages. It has always set from shore to sea in countless currents of adventure and speculation; but it has set most strongly from East to West. On its broad bosom the seeds of life and knowledge have been carried throughout the world. It brought the people of Tyre and Carthage to the coasts and oceans of distant worlds; it carried the English from Jutland across cold and stormy waters to the islands of their conquest; it carried the Romans across half the world; it bore the civilisation of the far East to new life and virgin western soils; it carried the new West to the old East, and is in our day bringing back again the new East to the old West. Religions, arts, tradings, philosophies, vices and laws have been borne, a strange flotsam, upon its unchanging flood. It has had its springs and neaps, its trembling high-water marks, its hour of affluence, when the world has been flooded with golden humanity; its ebb and effluence also, when it has seemed to shrink and desert the kingdoms set upon its shores. The fifteenth century in Western Europe found it at a pause in its movements: it had brought the trade and the learning of the East to the verge of the Old World, filling the harbours of the Mediterranean with ships and the monasteries of Italy and Spain with wisdom; and in the subsequent and punctual decadence that followed this flood, there gathered in the returning tide a greater energy and volume which was to carry the Old World bodily across the ocean. And yet, for all their wisdom and power, the Spanish and Portuguese were still in the attitude of our primitive man, standing on the sea-shore and looking out in wonder across the sea.
