THE NATURALIST'S VISION 363 



The field in which I have endeavored to awaken 

 interest by pointing out the way seems a fitting 

 culmination of the others. Obviously, things 

 must be named, and something of their relation-

I wish it were in my power to picture with 

 vividness, to give an impression of the conditions 

 that obtain in my tentative laboratory. Imagine a 

 room some twenty feet square, where over a hun-

 year, from January until late in August, their 

 song is incessant. Here are thrushes from Eu- 

 rope and the starling that characterizes that re- 

 gion ; a number of kinds of starlings from India,
