8 WORLD'S COiVGRESS 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

 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.

 Hall No. 23 of the Memorial Art Palace, at 2 P. m., on 

 successive davs to be determined hereafter. The interven-
