The connection of Portugal with Africa is an old, and--at least it was at first--an honorable one. The voyages of the Portuguese were the first to enrich geography with a knowledge of the African coasts, and so early as 1497 they took possession of the eastern shore by founding the colony of Mozambique. This rule, however, though nominally extending from Delagoa Bay to as far north as Cape Delgado, was confined to two or three isolated points, and nowhere, except on the Zambesi, affected more than the mere fringe of land bordering the Indian Ocean. On the Zambesi the Portuguese established stations at Senna, Tette, and Zumbo, which were used, though on the most limited scale, as missionary and trading centres; but these are at present all but abandoned and in the last stages of decrepitude. The right of Portugal to the lower regions of the Zambesi, notwithstanding its entire failure to colonize in and govern the country, can never be disputed by any European Power, though the Landeens, or Zulus, who occupy the southern bank, not only refuse to acknowledge the claim, but exact an annual tribute from the Portuguese for their occupation of the district. No one has ever attempted to define how far inland the Portuguese claim, founded on coast-possession, is to be considered good; but that it cannot include the regions north of the Zambesi--the Shiré Highlands and Lake Nyassa--is self-evident. These regions were discovered and explored by Livingstone. They have been occupied since his time exclusively by British subjects, and colonized exclusively with British capital. The claim of England, therefore--though nothing but a moral claim has ever been made--is founded on the double right of discovery and occupation; and if it were a question of treaty with the natives, it might possibly be found on private inquiry that a precaution so obvious had not been forgotten by those most nearly interested. On the other hand, no treaties exist with Portugal; there is not a single Portuguese in the country, and until the other day no Portuguese had even seen it. The Portuguese boundary-line has always stopped at the confluence with the Shiré of the river Ruo, and the political barrier erected there by Chipitula and the river Chiefs has been maintained so rigidly that no subject of Portugal was ever allowed to pass it from the south. Instead, therefore, of possessing the Shiré Highlands, that is the region of all others from which the Portuguese have been most carefully excluded.
