BLUE JAY. 197 



continued to see Blue Jays for six hundred miles up the Mis- 

 souri.* From these accounts it follows, that this species occupies, 

 generally or partially, an extent of country stretching upwards 

 of seventy degrees from east to west, and more than thirty 

 degrees from north to south; though, from local circumstances, 

 there may be intermediate tracts in this immense range, which 

 they seldom visit. 



* This fact I had from Captain Lewis.
