we secure representative collections of bird food material iron: this 
region in order that the fragments in these stomachs may oe success- 
fully identified. It is important to visit at least one inland and 
one coastal locality in making these collections. 
Upon completion of this work you should return to ITorfolk, 
Virginia and from there visit Currituck Sound for the purpose of 
securing information on the disease of swans and other water fowl 
known as "kern:". In the vicinity of Knotts Island and Swan Island a 
number of birds are found each year in early spring suffering from 
this peculiar malady. Sportsmen and others are much interested in 
this and it is desirable to ascertain the nature of this affection 
and its cause. 
Upon completion of this work, unless otherwise directed, 
you should return to the Washington office. 
With best wishes. 
Very truly yours. 
Chief of Bureau.
