Madame Redbelt 



I 



where their nests are, familiarizing themselves 

 with all its features. Any disturbance of these 

 is sure to be noticed ; but experiments designed 

 to ascertain how much of their behavior in this 

 respect arises from discriminating memory and 

 intelligence have had varying results. 



Prof. Jacques Loeb tells how an Ammophila 

 laden with a caterpillar too heavy to lift off 

 the ground went around the wall she was ac- 

 customed to flying over and worked her way 

 afoot to her nest by an unknown route, then 

 betrayed much stupidity because the hole had 

 been concealed by a clover-blossom. But other 

 individuals have been more clever at detecting 

 deceits practiced upon them by inquisitive natu- 

 ralists. 



Madame Redbelt carried her captive to the 

 mouth of the fourth hole, and, letting it drop, 

 hastily entered the nest, where she at once ran 

 against my fallen pebble, and pulled it out with- 

 out more ado. 



Doubtless she thought it a mere accident, 

 not noticing, or caring nothing for, any odor 

 of my hand that may have lingered about it.
