The rhinoceros would be even easier of approach than he is were it not for his attendant bird, a black slim-built fellow very like the king crow of India, who, in return I take it for his food, the parasitic insects on the chukuru, watches over his fat friend and warns him of the coming danger by springing up in the air and alighting smartly again with a peck on his back or head. This puts him on the alert, and he does his best, by sniffing and listening, to find out the point from which he is threatened, for his ears are quick and his scent excellent; but, as you are below wind of him, sound and smell travel badly, and his vision is by no means first rate. The natives by a figure transfer the connection between the bird and the beast to themselves, and when they wish to emphasise the great affection they bear you, or the great care they intend to take of you, address you as ‘my rhinoceros,’ an elliptical expression by which they mean to convey that they are your guardian birds. They are not always quite unfailing. Going out from Kolobeng after elephants I had heard of in the neighbourhood, I passed an old rain-doctor, whom I knew well, making rain with his pot on the fire, and his herbs and charms on the bubble. ‘Chukuru ami, where are you going?’ he asked. ‘To shoot elephants,’ I replied. ‘I was just making rain, but as you are my chukuru, I put it off till to-morrow.’ Is it necessary to say I was wet through in half an hour? A fine heavy thunderstorm was brewing whilst he was boiling. This rain-making is the Kafir’s pet superstition--the power is hereditary--believed in by the maker and his fellow-countrymen. Conditions difficult to keep are imposed, such as that the women are not to speak one word when at work in the fields: if the rain fails, why of course the women spoke!
