I examined carefully the whole alimentary canal, in order to see if there were any peculiarity which might account for the fact that this animal can subsist for months together without drinking, but found nothing. Other animals, such as the duiker ('Cephalopus mergens') or puti (of the Bechuanas), the steinbuck ('Tragulus rupestris') or puruhuru, the gemsbuck ('Oryx capensis') or kukama, and the porcupine ('Hystrix cristata'), are all able to subsist without water for many months at a time by living on bulbs and tubers containing moisture. They have sharp-pointed hoofs well adapted for digging, and there is little difficulty in comprehending their mode of subsistence. Some animals, on the other hand, are never seen but in the vicinity of water. The presence of the rhinoceros, of the buffalo and gnu ('Catoblepas gnu'), of the giraffe, the zebra, and pallah ('Antilope melampus'), is always a certain indication of water being within a distance of seven or eight miles; but one may see hundreds of elands ('Boselaphus oreas'), gemsbuck, the tolo or koodoo ('Strepsiceros capensis'), also springbucks ('Gazella euchore') and ostriches, without being warranted thereby in inferring the presence of water within thirty or forty miles. Indeed, the sleek, fat condition of the eland in such circumstances would not remove the apprehension of perishing by thirst from the mind of even a native. I believe, however, that these animals can subsist only where there is some moisture in the vegetation on which they feed; for in one year of unusual drought we saw herds of elands and flocks of ostriches crowding to the Zouga from the Desert, and very many of the latter were killed in pitfalls on the banks. As long as there is any sap in the pasturage they seldom need water. But should a traveler see the "spoor" of a rhinoceros, or buffalo, or zebra, he would at once follow it up, well assured that before he had gone many miles he would certainly reach water.
In the evening of our second day at Serotli, a hyaena, appearing suddenly among the grass, succeeded in raising a panic among our cattle. This false mode of attack is the plan which this cowardly animal always adopts. His courage resembles closely that of a turkey-cock. He will bite, if an animal is running away; but if the animal stand still, so does he. Seventeen of our draught oxen ran away, and in their flight went right into the hands of Sekomi, whom, from his being unfriendly to our success, we had no particular wish to see. Cattle-stealing, such as in the circumstances might have occurred in Caffraria, is here unknown; so Sekomi sent back our oxen, and a message strongly dissuading us against attempting the Desert. "Where are you going? You will be killed by the sun and thirst, and then all the white men will blame me for not saving you." This was backed by a private message from his mother. "Why do you pass me? I always made the people collect to hear the word that you have got. What guilt have I, that you pass without looking at me?" We replied by assuring the messengers that the white men would attribute our deaths to our own stupidity and "hard-headedness" (tlogo, e thata), "as we did not intend to allow our companions and guides to return till they had put us into our graves." We sent a handsome present to Sekomi, and a promise that, if he allowed the Bakalahari to keep the wells open for us, we would repeat the gift on our return.
After exhausting all his eloquence in fruitless attempts to persuade us to return, the under-chief, who headed the party of Sekomi's messengers, inquired, "Who is taking them?" Looking round, he exclaimed, with a face expressive of the most unfeigned disgust, "It is Ramotobi!" Our guide belonged to Sekomi's tribe, but had fled to Sechele; as fugitives in this country are always well received, and may even afterward visit the tribe from which they had escaped, Ramotobi was in no danger, though doing that which he knew to be directly opposed to the interests of his own chief and tribe.
