_29th May, 1869._--Many people went off to Unyembé, and their houses were untenanted; I wished one, as I was in a lean-to of Zahor's, but the two headmen tried to secure the rent for themselves, and were defeated by Mohamad bin Saleh. I took my packet of letters to Thani, and gave two cloths and four bunches of beads to the man who was to take them to Unyanyembé; an hour afterwards, letters, cloths, and beads were returned: Thani said he was afraid of English letters; he did not know what was inside. I had sewed them up in a piece of canvas, that was suspicious, and he would call all the great men of Ujiji and ask them if it would be safe to take them; if they assented he would call for the letters, if not he would not send them. I told Mohamad bin Saleh, and he said to Thani that he and I were men of the Government, and orders had come from Syed Majid to treat me with all respect: was this conduct respectful? Thani then sent for the packet, but whether it will reach Zanzibar I am doubtful. I gave the rent to the owner of the house and went into it on 31st May. They are nearly all miserable Suaheli at Ujiji, and have neither the manners nor the sense of Arabs. [We see in the next few lines how satisfied Livingstone was concerning the current in the Lake: he almost wishes to call Tanganyika _a river_. Here then is a problem left for the future explorer to determine. Although the Doctor proved by experiments during his lengthy stay at Ujiji that the set is towards the north, his two men get over the difficulty thus: "If you blow upon the surface of a basin of water on one side, you will cause the water at last to revolve round and round; so with Tanganyika, the prevailing winds produce a similar circulation.". They feel certain there is no outlet, because at one time or another they virtually completed the survey of the coast line and listened to native testimony besides. How the phenomenon of sweet water is to be accounted for we do not pretend to say. The reader will see further on that Livingstone grapples with the difficulty which this Lake affords, and propounds an exceedingly clever theory.] Tanganyika has encroached on the Ujiji side upwards of a mile, and the bank, which was in the memory of men now living, garden ground, is covered with about two fathoms of water: in this Tanganyika resembles most other rivers in this country, as the Upper Zambesi for instance, which in the Barotsé country has been wearing eastwards for the last thirty years: this Lake, or river, has worn eastwards too. _1st June, 1869._--I am thankful to feel getting strong again, and wish to go down Tanganyika, but cannot get men: two months must elapse ere we can face the long grass and superabundant water in the way to Manyuema.
