Thus during these three hours only six strangers 

 came. The raisin must have seemed almost inexhaust- 

 ible, and the watched ants in passing and repassing 

 went close to many of their friends ; they took no 

 notice of them, however, and did not bring any out of

 returned at 10.40. At 10.53 went back to the nest ;
