Winslow —The Mapping of Missouri. 73 
in 1775. A reduced copy-of portions of his map of North 
America is contained in Vol. I of the 100th Merid. Reports, 
opposite p. 512. It contains little detail of interest hére. 
The general course of the Mississippi river adjacent to Mis- 
souri is fairly well shown, though the stream is located about 
100 miles too far west. The latitudes of the mouths of the 
Ohio and of the Missouri are approximately correct.

Fie. 9. WINTERBOTHAM’S MAP — 1795. 
Initial Merid., presumably ai Greenwich. 
In Winterbotham’s History of 1795, published in New 
York, is a map of which Lieut. Warren, in the report of the 
United States Pacific Railway Surveys,* introduces a reduced 
copy as exhibiting the knowledge possessed of the territory 
west of the Missiasippi, before the Lewis and Clarke explor- 
ation of 1803-1806. A sketch is shown here of a portion of 
this map relating to Missouri and adjacent country. The 
courses of the Mississippi and Missouri rivers within the State 
approximate the locations as known to-day. The longitude of 
the former stream is at points nearly correct, and in this re- 
spect the map is much in advance of the others preceding it 
* Vol. XI, p. 16.
