163 REMARKS ON TRAVELS 
rich plains of the Wassoulo. Proceeding towards the 
east, and leaving the Dhioliba to the left, the traveller 
reached Tim^. 
The situation of Time is determined by two data : 
the one, that the march, throughout its whole length from 
Kakondy, was the same ; the caravan was equally nume- 
rous, and if the country is less mountainous, the travel- 
lers were more fatigued, which forms a compensa- 
tion : the other is furnished by the meridian altitude of 
the sun, twice taken at Time, by means of the length of 
the shadow. Imperfect as this observation probably was, 
we ought to have some respect for it, when it coincides 
with the data of the itinerary ; I shall soon resume this 
subject. 
To conclude the examination of this first part of 
the itinerary, I shall make some remarks on the situation 
of the country, which appears to be the spot where the 
waters of this portion of the African continent separate. 
The first great line of partition is that which divides the 
waters of the Senegambia from those of the Soudan. The 
mountains which form it have their nucleus at Timbo, 
where their distinction into separate ranges is totally lost. 
Thence one range diverges to the north, and another 
to the east, and it is remakable that the divisions of the 
countries or states correspond with the physical regions. 
Thus in the country called Fouta-Dhialon, Timbo and its 
mountains are the sources of the Rio - Grande, the 
Gambia, the Faleme, the Senegal, &c. The Soulimana
