EXPERIMENT WITH AN ATT A 177 



pilosa, belonging to a nest which I had bi ought back 

 witli me from Algeria. She was out hunting abouh 

 six feet from home, and I placed before her a large 

 dead bluebottle fly, which she at once began to drag 

 to the nest. I then pinned the fly to a piece of cork, 

 in a small box, so that no ant could see the fly until 

 she had climbed up the side of the box. The ant

 trying in every way to move it. Finding this still 

 impossible, she again returned to the nest, not chancing 

 to meet any of her friends by the way. Again she 

 emerged in less than a minute with 8 friends, and
