We have already made the reader acquainted with the heroic and more successful efforts of Colonel Baker, Pasha, in the same direction. He was not so much of a religious enthusiast as Colonel Gordon, did not rely on fate, but thought an imposing, organized force the best way to strike terror into these piratical traders, and at the same time inspire the negro races with better views of self protection. In the long and brilliant record which Colonel Baker made in Africa, the honors he gathered as a military hero bent on suppressing the slave trade will ever be divided evenly with those acquired as a dauntless traveller and accurate scientific observer. Let it not be thought that slave catching and selling is now extinct. True, the care exercised in the waters of the Red Sea and Indian Ocean, makes it difficult to run slave cargoes into Arabia and the further east. True, Baker’s expedition broke up a force of some two thousand organized kidnappers on the Upper White Nile, but these piratical adventurers are still abroad in more obscure paths and compelled to rely more on guile and cunning than on force for securing their prey. But let us pursue our journey from Kartoum toward the “Springs of the Nile.” We do not take the Blue Nile. That comes down from the east, and the Abyssinian mountains. We take the White Nile, which is the true Nile, and comes up from the south or southwest. And we must suppose we are going along with Colonel Baker on his first journey, which was one in search of the Nile sources. It was a scientific tour, and not an armed one like his second expedition. Entering the White Nile, we plunge into a new world——a region whose climate and animal and vegetable life, in brief, whose whole aspect and nature, are totally unlike those of the desert which stretches up to the walls of Kartoum. We are within the zone of regular rainfall, an intermediate region that extends to the margin of the great lakes, where we meet with the equatorial belt of perennial rains. Henceforth we have not only heat but moisture acting upon the face of nature. [Illustration: SWAMPS OF THE WHITE NILE.]
