WATCHING BIRDS AT A STRAW-STACK 219

 of the phenomena how are we to account for their 

 simultaneousness, and the other special features 

 belonging to them? 



It would seem as though either one and the same 

 idea were flashed suddenly into the minds of a 

 number of birds in close proximity to each other at 

 one and the same instant of time, or that this same 

 idea, having originated or attained a certain degree 

 of vehemence, at some one point or points repre-

 both the one and the other, for that individual birds 

 are capable of withstanding the collective influence 

 of the flock of which they form a part, I have ample 

 evidence. The old Athenians though slave-holders,
