COMMENTS ON MR. ROCKWELL'S OBSERVATIONS 

 By EDWARD R. WARREN 



Colorado Springs, Colorado 



The preceding notes were written by Mr. Rockwell at my 

 request after he had told me about the occurrence in conver- 

 sation, as it seemed so interesting as to be worthy of record. 



The animal seems to have been unable to realize that the 

 cots, which had not only supported the mattress in which the 

 nest was, but also covered the hole in the floor by which she 

 had entered the room, were missing. One would think she 

 would have noticed their absence at once, as heretofore they 

 had been there when she went to and fro. It is possible that 

 being a diurnal animal, her confusion may have been due to 

 being disturbed in the night, and that she was even unable to see 

 # well by such light as my friend may have had there, though 

 this last would not account for her actions. It is an interesting 

 speculation as to whether she would have acted as she did if it 

 had been davlight.
