330 LIVINGSTONE'S LAST JOURNALS. [Chap. XII. 



inundation to its having its source in the ocean : Herodotus 

 and Pliny to evaporation following the course of the sun. 



1st September, 1868. — Two men come from Casembe — I 

 am reported killed. The miningo-tree distils water, which 

 falls in large drops. The Luapula seen when the smoke 

 clears off. Fifty of Syde bin Omar's people died of small- 

 pox in Usafa. Mem. Vaccine vieus. We leave on the 

 25th, east bank of Moisi River, and cross the Luongo on the 

 28th, the Lofubu on the 1st October, and the Kalongosi on 

 the 7th. 



[Dr. Livingstone seems to have been unable to find 

 opportunity to make daily entries at this period. All was 

 turmoil and panic, and his life appears to have been in 

 imminent danger. Briefly we see that on his way back 

 from the Lake he found that his Arab associates of the last 

 few months had taken up Casembe's cause against the 

 devastating hordes of Mazitu, who had swept down on these 

 parts, and had repulsed them. But now a fresh complication 

 arose ! Casembe and Chikumbi became alarmed lest the 

 Arabs, feeling their own power, should turn upon them and 

 possess the whole country, so they joined forces and stormed 

 Kombokombo, one of the leading Arabs, and with what suc- 

 cess we shall see. It is a fair specimen of the unaccount- 

 able complications which dog the steps of the traveller, 

 where war is afoot, and render life a misery. He writes as 

 follows on the 5th October : — ] 



I was detained in the Imbozhwa country much longer 

 than I relished. The inroad of the Mazitu, of which 

 Casembe had just heard when we reached the Mofwe, was 

 the first cause of delay : he had at once sent off men to 

 verify the report, and requested me to remain till his 

 messengers should return. This foray produced a state 

 of lawlessness in the country, which was the main reason of 

 our further detention.
