Stanley once penetrated into one of these great forests and was so overwhelmed by the majesty and solemn stillness of the scene, that he forgot where he was, and his imagination went back to the primeval days when that great, still forest was sown, till the silent trees seemed monuments of past history. But still, this district of Manyema (pronounced in various ways), he does not think so interesting as that of Uregga. In speaking of the Lualaba, after describing the various ways in which it is spelled and pronounced, he says if he could have it his own way he would call it "Livingstone River, or Livingstone's Lualaba," to commemorate his discovery of it and his heroic struggles against adversity to explore it. The letter in which he thus speaks of this region is dated November 1st, 1876. In three days he says he is going to explore this mysterious river to the utmost of his power. Two days previous to this letter, he wrote a long one on the horrors of the slave-trade that casts a pall as black as midnight over all this tropical beauty. He says that from Unyanyembe to Ujiji one sees horrors enough, but in this region they are multiplied tenfold. The traffic in slaves is so profitable and keeps up such a brisk trade with Zanzibar and the interior of Africa, that the native chiefs enter into it on the grandest scale, or rather it is more accurate to say, banditti under the leadership of so-called chiefs enter into it thus, and carry it on with remorseless zeal. Raids are made on small independent villages, the aged are slain and hung up to terrify other villages into a meek acquiescence in their demands, and young men, young women, and children are marched off to Ujiji, from whence they are taken to Zanzibar, becoming, by their cruel treatment on the route, living skeletons before they reach their destination. Gangs, from one hundred to eight hundred, of naked, half-starved creatures Stanley met in his travels, and he wonders that the civilized world will let insignificant Zanzibar become the mart of such an accursed, cruel traffic. There are regular hunting-grounds for slaves. When the business is dull, the inhabitants are left to grow and thrive, just like game out of season in a gentleman's park; but when the business begins to look up, the hunt begins, and the smiling villages become arid wastes. The country, long before he reached Nyangwe, was a wilderness, where a few years before dwelt a happy population. Stanley gives extracts from his diary, showing up the horrors of this system, which make the heart sicken as it thinks of what is daily transpiring in this unknown land. Livingstone saw enough when he was at this place to awaken his deepest indignation, but since that time the Arabs have pushed further inland, and swept, with the besom of destruction, districts that in his time had been but slightly touched.
