Mochokotsa, a messenger from Sekeletu, met us on the 17th, with another request for the Doctor to take ivory and purchase a horse. He again declined to interfere. None were to come up to Sekeletu but the Doctor; and all the men who had had smallpox at Tette, three years ago, were to go back to Moshobotwane, and he would sprinkle medicine over them, to drive away the infection, and prevent it spreading in the tribe. Mochokotsa was told to say to Sekeletu that the disease was known of old to white men, and we even knew the medicine to prevent it; and, were there any danger now, we should be the first to warn him of it. Why did not he go himself to have Moshobotwane sprinkle medicine to drive away his leprosy. We were not afraid of his disease, nor of the fever that had killed the teachers and many Makololo at Linyanti. As this attempt at quarantine was evidently the suggestion of native doctors to increase their own importance, we added that we had no food, and would hunt next day for game, and the day after; and, should we be still ordered purification by their medicine, we should then return to our own country. The message was not all of our dictation, our companions interlarded it with their own indignant protests, and said some strong things in the Tette dialect about these "doctor things" keeping them back from seeing their father; when to their surprise Mochokotsa told them he knew every word they were saying, as he was of the tribe Bazizulu, and defied them to deceive him by any dialect, either of the Mashona on the east, or of the Mambari on the west. Mochokotsa then repeated our message twice, to be sure that he had it every word, and went back again. These chiefs' messengers have most retentive memories; they carry messages of considerable length great distances, and deliver them almost word for word. Two or three usually go together, and when on the way the message is rehearsed every night, in order that the exact words may be kept to. One of the native objections to learning to write is, that these men answer the purpose of transmitting intelligence to a distance as well as a letter would; and, if a person wishes to communicate with any one in the town, the best way to do so is either to go to or send for him. And as for corresponding with friends very far off, that is all very well for white people, but the blacks have no friends to whom to write. The only effective argument for the learning to read is, that it is their duty to know the revelation from their Father in Heaven, as it stands in the Book. Our messenger returned on the evening of the following day with "You speak truly," says Sekeletu, "the disease is old, come on at once, do not sleep in the path; for I am greatly desirous (_tlologelecoe_) to see the Doctor."
