694 APPENDIX. 



Brewster has suggested to me that both the dark and light forms of the Great Horned Owls which occasion- 

 ally ooour in Massachusetts, are birds which have been raised there. If this is so we must consider them as 

 specimens that have reverted toward the original stock which once oocufiied this section in common when 

 both B. V. arotious and B. v, saturatus followed up the retreating ice sheet of the glacial period.
