that these clays' journeys were journeys on foot. Let us 
work on these data, and see whether they confirm the 
course of the river drawn from the itinerary of M. CailUe. 
Can these days* journeys be computed at more than 
twenty-one geogi-aphical miles ? This can scarcely be ad- 
mitted ; but should they even be extended to twenty-two 
miles and in a direct line, it would be on the whole two 
hundred and twenty miles, which in the above direction 
would not reach the ninth meridian west of Paris. 
While M. Caillie was at Kiebala, he was told the 
distances and bearings of Sego, which differ very little 
from the position resulting from that of Elimane in the 
opposite direction ; and if the river was here carried 
eastward, as it is found in all the maps calculated from 
Park's travels, there would no longer be any agreement 
between these two different sources of information. If, 
on the contrary, these respective data are preserved, they 
naturally harmonize, and the northerly course of the 
stream is confirmed. 
Besides, the latitude of Sego, although not yet ob- 
served, cannot greatly differ from that of Sami, which 
is near it : the observation there made by Mungo Park 
gives thirteen degrees seventeen minutes, and this is 
perhaps, a little too northerly. The approximative position 
of Sego, resulting from various data, and which I have 
adopted as a medium, would thus be, latitude thirteen 
degrees longitude, nine degrees west.
