The season which the author has in mind, in 

 beginning the following descriptions, is for the 

 latitude of southern Oregon, January 20th ; for 

 Portland, February ist ; and for northern Wash- 

 ington, February loth to 15th. 



The seasons are supposed to move on, in the 

 book, with the months, till one arrives at the 

 "Winter Birds." We should remember, how-

 part, to be observed by July ist.

 referred to the last chapter of the book, "A

 in some part of the territory for which this book 

 is prepared.
