CAPTAIN TUCKEY’S NARRATIVE. 185 
I this day visited the valley of Kincaya, where I was 
told a man had canoes to sell; but he was gone into the 
country. ‘The structure of the valley we found to consist 
of a vast mass of slate, the strata dipping 45° to the S.W. 
The hills on each side were also composed of slate, with 
masses ot quartz. Here I purchased some smoked fish. 
Here also I again met the Embomma slave trader. |The 
manner of conducting the traffic in slaves, we found to be 
thus: The slave merchant quits Embomma with three 
men, each carrying a jar of brandy, and a piece of cloth; 
on a bargain for a slave being concluded, a jar of brandy 
is then drunk, and a proportion of the cloth is given to the 
Chenoo and other great men as presents; the seller then 
sends one of his own men back with the trader to receive 
the price of the slave at Embomma, or at any intermediate 
place that the feuds or other impediments to tranquillity 
may render expedient. 
August 27. ‘This morning the gangam kissey returned, 
and we learnt that he had denounced three men of another 
village as the poisoners of the man that died, and that the 
accused were immediately to undergo the ordeal of chewing 
poisonous bark, which, if they were guilty, they would re- 
tain in the stomach, and thus it would occasion their 
death ; but if innocent, they would vomit it up again
