New Jersey, and the more frequent occurrence there of the 

 irregular winter visitants. As yet there is little or no detailed 

 information of the migration in this remote section, some of 

 which is still unvisited at any season of the year. Large 

 areas are relatively difficult of access, and some primeval 

 timber still remains. Discoveries of interest undoubtedly 

 await those who will take the trouble to go there. 



In most of the area observation is so incomplete compared 

 with Englewood that migration dates are given only when 

 better than those obtained at this station.

 arranged in the order followed in this book, will enable the
