per acre if the sparrows are included. The 

 total number of species observed was 38, and 

 the number of birds identified was 4,257. 

 Fifty-nine per cent, of the individuals seen 

 were bronzed grackles, 13.3 per cent, were 

 English sparrows, 12.5 per cent, were cow- 

 birds, 2.5 per cent, were mourning-doves, and 

 2.3 per cent, were meadow-larks. Nearly 90 

 per cent, of all the birds on the farm thus 

 belonged to these five species, and to them was 

 due virtually all the impression which was 

 being made by birds on the plant and insect 

 life of this tract. 



THE INTERNATIONAL CONGRESS OF 

 AMERICANISTS. 



We have already called attention to the 

 fact that the fifteenth International Congress 

 of Americanists will be held at Quebec from 

 September 10 to 16 of next year. The regula- 

 fions adopted by the committee of organization 

 are as follows: 



Papers will be listed on receipt of title. 



Papers will not be assigned a place on the pre- 

 liminary daily program unless an abstract has 

 been received, as required by the rules and regu- 

 lations of the congress. 



Papers to be read will be arranged according to 

 subject-matter, in a number of divisions corre- 

 sponding to those of the general program; and 

 papers belonging to the same division will be pre- 

 sented, so far as feasible, on the same day. 



Papers in each division will take precedence in 

 the order of the receipt of abstracts. 



Authors who intend to submit more than one 

 paper to the congress are requested to designate 

 the paper they desire to read first. The rest of 

 their papers will be placed at the end of the pre- 

 liminary program of the respective divisions. 



In order to insure the prompt publication of the 

 proceedings of the congress, the committee recom- 

 mends to the congress to set the latest date for 

 the receipt of completed manuscripts and of notes 

 of discussions, October 1, 1906.
