inherent in the general character of the region, partly adventitious or accidental, contributed at an early date, and until very recently, to emphasize and enlarge the importance consequent upon the geographical situation and physical conformation of this narrow barrier between two great seas. For centuries the West India Islands, circling the Caribbean, and guarding the exterior approaches to the Isthmus, continued to be the greatest single source of tropical products which had become increasingly necessary to the civilized nations of Europe. In them, and in that portion of the continent which extended on either side of the Isthmus, known under the vague appellation of the Spanish Main, Great Britain, during her desperate strife with the first Napoleon,—a strife for very existence,—found the chief support of the commercial strength and credit that alone carried her to the triumphant end. The Isthmus and the Caribbean were vital elements in determining the issue of that stern conflict. For centuries, also, the treasures of Mexico and Peru, upon which depended the vigorous action of the great though decadent military kingdom of Spain, flowed towards and accumulated around the Isthmus, where they were reinforced by the tribute of the Philippine Islands, and whence they took their way in the lumbering galleons for the ports of the Peninsula. Where factors of such decisive influence in European politics were at stake, it was inevitable that the rival nations, in peace as well as in open war, should carry their ambitions to the scene; and the unceasing struggle for the mastery would fluctuate with the control of the waters, which, as in all maritime regions, must depend mainly upon naval preponderance, but also in part upon possession of those determining positions, of whose tenure Napoleon said that "war is a business of positions." Among these the Isthmus was chief.

The wild enterprises and bloody cruelties of the early buccaneers were therefore not merely a brutal exhibition of unpitying greed, indicative of the scum of nations as yet barely emerging from barbarism. They were this, doubtless, but they were something more. In the march of events, these early marauders played the same part, in relation to what was to succeed them, as the rude, unscrupulous, lawless adventurers who now precede the ruthless march of civilized man, who swarm over the border, occupy the outposts, and by their excesses stain the fair fame of the race whose pioneers they are. But, while thus libels upon and reproaches to the main body, they nevertheless belong to it, share its essential character, and foretell its inevitable course. Like driftwood swept forward on the crest of a torrent, they betoken the approaching flood. So with the celebrated freebooters of the Spanish Main. Of the same general type,—though varying greatly in individual characteristics, in breadth of view, and even in elevation of purpose,—their piratical careers not only evidenced the local wealth of the scene of their exploits, but attested the commercial and strategic importance of the position upon which in fact that wealth depended. The carcass was there, and the eagles as well as the vultures, the far-sighted as well as the mere carrion birds of prey, were gathering round it. "The spoil of Granada," said one of these mercenary chieftains, two centuries ago, "I count as naught beside the knowledge of the great Lake Nicaragua, and of the route between the Northern and Southern seas which depends upon it."
