Nor did he neglect that naval arm which has been of so great service to many countries. Prussia's desire to have a navy has raised many smiles, and caused much laughter, in this century, as if it were something new; whereas it is an ancient aspiration, and one which all Prussian sovereigns and statesmen have experienced for two hundred years, though not strongly. The Great Czar, who came upon the stage just after the Great Elector left it, did not long more for a good sea-coast than that Elector had longed for it. Frederick William could not effect so much as Peter effected, but he did something toward the creation of a navy for Prussia. His reluctance in parting with a portion of Pomerania was owing to his commercial and maritime aspirations. "Of all the princes of the house of Brandenburg," says Ranke, "he is the only one who ever showed a strong predilection for maritime life and maritime power. It was the dream of his youth that he would one day sail along shores obedient to his will, all the way from Custrin, out by the mouths of the Oder, across to the coast of Prussia. His sojourn in the Netherlands had strengthened, though it had not inspired, his love of the sea. The best proof how painful this cession was to the Elector is the fact that he shortly afterward offered to the crown of Sweden, not alone the three sees of Halberstadt, Minden, and Magdeburg, but a sum of two millions of thalers in addition, for the possession of Pomerania." The same writer says of the Great Elector elsewhere, that "his mind had a wide grasp; to us it may seem almost too wide, when we call to mind that he brought the coast of Guinea into direct communication with Brandenburg, and ventured to compete with Spain on the ocean." When he died, the population of his dominions amounted to one million five hundred thousand.
