On the Climate of the 



this, however, no argument can be drawn in regard to the climate, 

 for it flourishes also in the vicinity of Philadelphia,* New-York,! 

 and Albany ; the last of which is in latitude 42° 39* N., about nine 

 minutes north of the northern boundary of the state of Illinois. It 

 is moreover cultivated with success in different parts of Europe. 



But admitting as has been asserted by some authors, that this 

 tree is indigenous to the United States, it can easily be made ap- 

 parent that this affords no proof, that in the basin of the Missis- 

 sippi the temperature of the climate is higher than on the Atlantic 



According to the younger Michaux,| " in the Atlantic states, 

 the Catalpa begins to be found in the forests on the banks of the 

 river Savannah, near Augusta, in Georgia ; and west of the Alle- 

 ghanies, on those of the Cumberland, between the 35th and 36th 

 degrees of latitude. Further south it is more common, and abounds 

 near the borders of all the rivers which empty into the Mississip- 

 pi, or which water the province of West Florida." He further re- 

 marks : " I have been assured that it is particularly abundant on the 

 Escambia or Conechu, which discharges itself at Pensacola. It is 

 remarkable that the Catalpa should not exist in the lower part of 

 the Carolinas and of Georgia and East Florida, which lie so near 

 the country of its natural growth, and where stocks that have 

 been planted for ornament about the houses shoot with extraordin- 

 ary vigour." 



In treating of this tree, Mr. Elliott, in his " Sketch of the Bot- 

 any of South Carolina and Georgia," observes that it grows in the 

 middle and upper parts of these states, along the margins of riv 

 ers.§ 



The Catalpa, therefore, if at all indigenous to the United States, 

 is extremely circumscribed rh its locality, and its appearance 

 depends upon causes in no way connected with climate ; for on 

 the sea-coast it is not observed north or south of South Carolina 

 and Georgia, whereas in the interior, it is found on the Wabash 

 river, at least six or seven degrees farther north. Certainly there 

 can be no similarity of climate between these two sections of our
