FERTILE WOEKERS. 35 



continually moved their antennge caressingly. Thia 

 sort of attention continued until the queen, escorted bji 

 workers, disappeared in one of the galleries. She was

 The workers were fresh from their own natural home, and 

 the queen had been in an artificial home for a month.' 



In no case, however, when I have put a queen into 

 one of my nests has she been accepted. 



Possibly the reason for the difference may be that 

 the ants on which I experimented had been long living 

 in a republic ; for, I am informed, that if bees have been 

 long without a queen it is impossible to induce them to 

 accept another. 



Moreover, I have found that when I put a queen 

 with a few ants from a strange nest they did not 

 attack her, and by adding others gradually, I succeeded 

 in securing the throne for her. 



It is generally stated that among ants the queens 

 only lay eggs. This, however, is not correct. 



Denny ' and Lespes ^ have shown that the workers
