,i CHAPTER 111. 
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 could not, from its nature 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 con- ' 
cerning the subject ; or whether some other traveller, more fortunate (for 
he cannot possess more zeal, enterprize, temper, or firmness) should com- 
plete Mr. Park's work ; 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 require 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 Expedi- 
tion, 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 which affect the position
