Our preparations were soon completed. Igubo gave his son charge to behave well, and to bring no discredit upon his white friends. Kate urged us all to take care of ourselves, and not to run into unnecessary danger. The whole party accompanied us down to the canoe. We had chosen the _Gazelle_, as the best of the two. As the wind was fair, we hoisted our sail and steered merrily down the river towards the lake. We had no difficulty, as we passed along, in supplying ourselves with food. Wild ducks of all sorts abounded. Among them were numbers of the Egyptian goose. We saw several of them ahead, and made chase. Being heavy of wing, we found they could not rise out of the water, and we caught four or five with our hands as we passed by. A little further on we neared a bank on which a large flock of ducks were seated. Leo and I fired at the same time, and on landing we picked up a dozen ducks and three geese which we had knocked over. Among them was a large black goose, which we saw in great numbers walking slowly about and picking up their food. The specimen we killed had a small black spur on its shoulder--as has the armed plover--and as strong as that on the heel of a cock; but the birds, it is said, never use them except in defence of their young. They are said always to choose ant-hills for their nests. The ants cannot hurt the eggs, and the material of which the hills are composed assists probably in hatching the eggs, as the sand does those of the ostrich. I had hitherto held very little conversation with Mango. He had, however, picked up enough English to make himself understood, and during this trip I was able to ascertain some of his peculiar notions. We kept for some time along the north shore of the lake. We were nearing a point when we saw a beautiful water-antelope, known under the name of _mochose_. Before I could stop him, Leo had lifted his rifle and fired. The poor animal was hit, and, as is always the case, instead of flying along the shore, leaped into the water and began to swim across the lake. We immediately made chase, for though we had ducks enough for food, venison was not to be despised. I saw Mango waving his hands and muttering in a peculiar manner. The mochose swam well, but we soon gained upon it; and I was anxious to put it out of its sufferings, for a red mark which appeared in its wake showed that it must have been badly wounded. Just as we neared it, a long snout projected above the water. It was that of a crocodile. The next instant the poor mochose and the hideous monster sank together. Mango uttered an expression of disappointment; and when I questioned him, he said that he had been praying to his fetish, who was himself a crocodile, that we might obtain the venison, but that the fetish would not hear him.
