Lastly, it may be mentioned tliat the approval of the leaders of ornitholo- 

 gy in this country has been heartily given to the plan of this work, and im- 

 portant assistance offered by them in the way of access to unique specimens 

 in cabinets, notes from private journals, etc. Among these may be men- 

 tioned Dr. Elliott Coues, Naturalist of the United States Geological Sur- 

 vey; Prof. J A. Allen, of the Museum cf Comparative Zoology at Cam- 

 bridge, Mass.; Captain Charles Bcndiro, U. S. A., prominent members of 

 the Nuttall Ornithological Club, and other gentlemen very well known. 



It is safe to assume, therefore, that this book will take the place cf a 

 standard work, and become a necessary part of the library of every lover of 

 birds, or student of th.eir nests and eggs. 



N"OTE. — !\Ioinoranda sent to the author upon any occurrences related to 

 the subject, us outlined above, would be highly valued. Nothing ought to 

 be thought too insignificant, — merely a careful record of dates of nest-build- 

 ing and egg-laying actually observed in any one locality, for example, being 

 of importance. The author will take pains to give due thanks and credit 

 for all such information.
