flock of eighty Bank Swallows and twelve Purple Martins. After this 

 date only the usual summer numbers of the breeding species were seen; 

 there were no more migrants. The I'lirple Martin which seemed to be 

 less affected by weather conditions after arrival than the other species, 

 was orthodox in its arrival which occurred on a cloudy morning after a 

 clear night. 



There is no other record so complete; and it can not be stated whether 

 this relation Ijetween weather and migration is a fixed one, but in regard 

 to the migratory movements of Swallows in 1903, it may be said that the 

 relation was so close that one could predict the numbers to l^e found on 

 any day from the condition of the weather.
