But on watching Pyjalé it appeared that it did not stick to naked human feet to anything like the same extent. Pyjalé told me, and I afterwards saw it actually done, that it was possible to run down ostrich and the heavy antelope, such as eland, when the ground was in this state.

Returning we found the boys well on with their chopping out. Towards evening we started for home, being much troubled with swollen rivers. Most of the boys walked through the rivers when we could find a place where the current was not too strong. The heavy tusks, of course, kept them on the bottom. But it was a curious sight to see them calmly marching in deeper and deeper until their heads went right under, reappearing again close to the other bank. Of course, the distance they thus traversed was only a few yards, but for fellows who cannot swim it was not bad.

One camp from home (the safari) we slept near some flooded wells. The boys took their tusks to scrub them with sand and water, the better to make an appearance on the morrow when we should rejoin the safari. This is always a source of joy to Wanyamwezi, to carry ivory to the base. When allowed to do so they will spend hours dancing and singing their way into the camp. The women turn out, everybody makes a noise of some kind, from blowing a reed pipe, to trumpeting on a water buck horn or beating a drum or a tin, in fact anything so that it produces noise.

While they were scrubbing the tusks one of these slipped from the boy’s hands into a well. I heard of it and went to see what could be done. To test the depth I tried one of Pyjalé’s 9 ft. spears. No good. Then I tied another to it, but even then I could not touch bottom. Pyjalé said the bottom was very far. Then I looked at one of my boys squatting on the edge of the well. He had been a coast canoe-man shark-fisher—than whom no finer watermen exist—and knew what I meant without a word passing. He tied his cloth between his legs and stripped his upper body. Then jumping into the air he twisted half round and went down head first into the very middle of the well. It seemed ages before his head reappeared. At last it did so, but only for an instant. Down again; apparently he had not found it the first time. After another long wait he came up with the tusk and swimming or treading water. Eager hands clutched the tusk and drew it out, the boy crawled out himself. This particular tusk weighed 65 lb., the length being almost the diameter of the well, so it had to be brought up end on. How he did it I cannot imagine. The water was the colour of pea-soup, and a scrubbed tusk is like a greasy pole to hold. Of course, it would not weigh 65 lb. when submerged, but it was a pretty good effort I thought. I know I would not have gone 20 ft. or 30 ft. down that well for any number of tusks.

These boys have the most extraordinary lungs. I once sent one of them down to disentangle the anchor of a motor launch, which had got foul of something. There were about four fathoms of chain and the boy went down this hand over hand. I only wanted him to clear the anchor, when we would heave it up in the ordinary way. But presently up the chain came the boy and the anchor.

On the morrow we entered Bukora again, with fourteen fine white tusks. We had a great reception at our camp. The natives, too, were rather astonished at our rapid success. Pyjalé stalked along without any show of feeling.

The boys who had stayed behind had nothing to report except the loss of three of our sheep by theft. Now it was essential to nip this kind of thing in the bud. I did nothing that day, merely sending Pyjalé to his home with a handsome present. I knew he would put it round as to the kind of people we were. Natives always exaggerate enormously when back from a scurry in the bush, and his account of our doings would probably have made me blush had I heard it.

Next day when Pyjalé came with a pot of fresh cow’s milk as a present, I asked him if he had heard anything about our sheep. He said no. I asked him to point me out the village which had stolen them. He said they would kill him if he did so. Therefore he knew. I then said that he need not go with me, if only he would indicate it. He said the village with the three tamarind trees was where the thieves lived.

I went over quietly, as if looking for guinea-fowl, in the evening. The village was quite close to our camp. When their stock began to come in I signalled up some boys. We walked up deliberately to the herds, no one taking any great notice of us. I separated out a mob of sheep and goats and we started driving them towards camp, but very quietly and calmly. It is wonderful how imitative Africans are. If you are excited they at once become so. If you are calm and deliberate, so are they.
