Art. XV. Professor Bigelow on the comparative For- 

 wardness of the Spring in different Parts of the United 

 States, in 1817. 



W E have been favpured with an ingenious memoir on this 

 subject, by the author. Professor Bigelow of Boston ; it is a 

 part of the fourth volume of the Memoirs of the American 

 Academy of Arts and Sciences. 



Professor Bigelow, availing himself of a hint given him 

 some years ago by the late venerable Dr. Muhlenberg of 

 Pennsylvania, ascertained, through the medium of corres- 

 pondence with accurate observers in different parts of North 

 America, the time of flowering, for "1817, of the common 

 fruit-trees and a few other plants" — " found in most parts of 

 the United States." 



The peach-tree was the one most uniformly returned, and 

 the following table exhibits the time of its flowering, in places 

 sufficiently numerous and remote, to afford a fair specimen of 

 these observations : 



Places. Xiot Long. Peach-tree in blossom.
