APPENDIX. 



For the use of beg-inners who do not collect and have not access to 

 collections of skins, and who may consequently find the technical keys 

 difficult, the following- color key has been made to the more conspicuous 

 birds one meets in the field. Its use by any one who has skins to consult 

 is earnestly deprecated, as it is much better to work a little harder and 

 learn more — to begin at the beginning-, with " Keys to Orders,' and follow 

 through to the species, so learning- something- of the classification of birds, 

 something of their fundamental relations, rather than to find their mere 

 names arbitrarily by the use of purely superficial characters.
