8 WORLD'S CONGRESS ON ORNITHOLOGY. 
of the Congress will doubtless be largely composed of those 
who, through esthetic feelings and humane sympathy, rather 
than intellectual apprehension, have been attracted to the 
subject, and they will prove a ready means of popularizing 
the science. 
Under the head of aviculture, the economist will be given 
the best results and profitable advice of those who have 
paid special attention to cultivation of the birds which 
have proved useful, or otherwise practically interesting to

specimens needed by scientists.

these divisions of the subject will largely depend the success 
of the Congress.

few years is forcing the truth of such conclusions upon us. 
The connection is not remote between the destruction of 
birds and the recent alarming increase of insect life that has 
been so ruinous to fruit and grain. - 
The study of birds opens so wide a field of interest and 
importance that we feel justified in believing that this Con-

minds. 
The date assigned for this Congress is the during week 
beginning October 16th. Several sessions will be held, in 
Hall No. 23 of the Memorial Art Palace, at 2 P. M., on 
successive days to be determined hereafter. The interven-
