“I know nothing that distinguishes the uncontaminated African from other degraded peoples more than their entire reasonableness and good sense. It is different after they have had wives, children, and relatives kidnapped, but that is more than human nature, civilized or savage, can bear. In the chase in question indiscriminate slaughter, capture, and plunder took place. A very large number of very fine young men were captured and secured in chains and wooden yokes. “I came near the party of Syed Ben Habib, close to a point where a huge rent in the Mountain of Rua allows the escape of the great river Lualaba out of Lake Moora, and here I had for the first time an opportunity of observing the difference between slaves and freemen made captive. When fairly across the Lualaba, Syed Ben Habib thought his captives safe, and got rid of the trouble of attending to and watching the chained gangs by taking off both chains and yokes. All declared joy and a perfect willingness to follow Syed to the end of the world or elsewhere, but next morning twenty-two made clear of two mountains. “Many more, seeing the broad Lualaba roll between them and the homes of their infancy, lost all heart, and in three days eight of them died. They had no complaint but pain in the heart, and they pointed out its seat correctly, though many believe the heart situated underneath the top of the sternum, or breast bone. This to me was the most startling death I ever saw. They evidently die of broken-heartedness, and the Arabs wondered, seeing they had plenty to eat. “I saw others perish, particularly a very fine boy ten or twelve years of age. When asked where he felt ill, he put his hand correctly and exactly over the heart. He was kindly carried, and, as he breathed out his soul, was laid gently on the side of the path. The captors are not unusually cruel. They were callous. Slaving hardened their hearts.
