 of colored plates, from drawings by Louis Agassiz Fuertes and Bruce 

 Horsfall, accurately representing all the plumages of North American

 W. W. Cooke, from records in the Biological Survey. It gives the aver- 

 age migration dates of Warblers at hundreds of localities, often for long 

 periods of time. Tne data for the Redstart, for example, represent the 

 work of over 50 observers for a total of 427 years !

 of our December, 1903, issue, containing the first ttvo col- 

 ored Warbler plates, to all subsa-ibers to Vol. VI of BIRD-
