The Delaware Valley Ornithological Club.—Recognizing 
the advantages to be gained by combined work, a number of ornitholo- 
gists residing in the vicinity of Philadelphia have organized the Dela- 
ware Valley Ornithological Club, for the study of the birds of south- 
eastern Pennsylvania and southern New Jersey, with especial reference 
to their migration in the valley of the Delaware River. The active 
membership of the club is limited, and consists only of those who have 
had considerable experience in field work, and are known to be 
thoroughly reliable. An associate membership has been added to 
include beginners in the study who can furnish data subject to the 
approval of the active members, and in return can receive the benefit 
of their experience. 
The following is a brief outline of the methods of work of the 
club: Daily field notes are taken by the members, and recorded 
systematically on monthly charts containing vertical columns for the 
days and horizontal ones for the birds in the order of their occurrence 
during the month. The spaces are sufficiently large for recording the 
number of birds seen (as recommended by Mr. Batchelder, in the 
April number of 7 he Auk), and short abbreviated notes as to singing,
