CHAPTER III. 
Construction of the Geography of Mr. Park's Expedition into Africa. 
I NEXT proceed to the detail of Mr. Park's geographical materials. Should 
it be objected that I have been too diffuse and particular, in this part, 
I can only say, that since the information itself ccmld not, from its na- 
ture be correct, it became the more necessary to investigate it closely, and 
also to place, not only the result but the detail of the investigation, together 
with the original documents themselves,' in the form of notes, in the hands 
of the public, that the true grounds of the construction, might be known. 
For whether it may happen, that no further lights should ever be obtained, 
concerning the subject ; or whether some other traveller, more fortunate 
(for he cannot possess more zeal, enterprize, temper, or firmness) should 
complete Mr. Park's v/ork; in either case, the original documents, as well as 
the mode of working them up, should be recorded ; in the former, that we 
may know how to appreciate them ; in the latter, how best to improve them. 
The successor of Mr. Park, cannot have too extensive a knowledge of the 
detail of his predecessor's work ; in order that he may know what parts re- 
quire correction ; and how to avoid delays, from a useless attention to 
objects, that are already attained. 
Two new Maps have been constructed for the occasion. The one con- 
tains the Progress of Discovery and Improvement in various 
parts of North Africa ; the other, the Geography of Mr. Park's Expe- 
dition, as well as the result of his particular inquiries in the same quarter; 
on a more extended scale. The present remarks and discussions refer par- 
ticularly to the latter. 
In the construction of this map, it is first required to state those points, 
on which Mr. Park's outset depends ; as also those vt'hich affect the posi-
