Now, looking up again, I saw several of them. How high they were! At times they would appear to be quite still in the air; at other times they would soar. They were so high that I do not see how they could possibly see the trees; every thing must have been in a haze to them; monkeys, of course, could not be seen. They were, no doubt, amusing themselves, and I wonder if they tried to see how near they could go to the sun. Some at times flew so high that I lost sight of them. Oh, how I longed to kill a guanionien; but I never was able to do it. Once I examined one, but it was dead, and had been killed by spears as it had come down and seized a goat. The natives had kept it for me; but when I returned to the village it was quite spoiled and decomposed, the feathers having dropped out. Several times I was on the point of killing one, but never was in time. My men went hunting that morning, while I remained alone in the camp, for I felt tired, and wanted to write up my journal, and to describe all the things I had seen or heard during the past few days. In the afternoon I thought I would ramble round. I took a double-barreled smooth-bore gun, and loaded one side with a bullet in case I should see large game; the other barrel I loaded with shot No. 2. Then I carefully plunged into the woods till I reached the banks of a little stream, and there I heard the cry of the mondi (_Colobus Satanus_), which is one of the largest monkeys of these forests. From their shrill cries, I thought there must be at least half a dozen together. I was indeed glad that I had one barrel loaded with big shot. If the mondis were not too far off, I would be able to get a fair shot, and kill one. I advanced very cautiously until I got quite near to them. I could then see their big bodies, long tails, and long, jet-black, shining hair. What handsome beasts they were! what a nice-looking muff their skins would make! I thought. Just as I was considering which of them I would fire at, I saw some big thing, like a large shadow, suddenly come down upon the tree. Then I heard the flapping of heavy wings, and also the death-cry of a poor mondi. Then I saw a huge bird, with a breast spotted somewhat like a leopard, raise itself slowly into the air, carrying the monkey in its powerful finger-like talons. The claws of one leg were fast in the upper part of the neck of the monkey; so deep were they in the flesh that they were completely buried, and a few drops of blood fell upon the leaves below. The other leg had its claws quite deep into the back of the monkey. The left leg was kept higher than the right, and I could see that the great strength of the bird was used at that time to keep the neck, and also the back of the victim, from moving. The bird rose higher and higher, the monkey's tail swayed to and fro, and then both disappeared. It was a guanionien. Its prey was, no doubt, taken to some big tree where it could be devoured.
