Thus during these thi-ee hours only six strangert 

 came. The raisin must have seemed almost inexhaust-

 went close to many of their friends; they took no 

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

Again (on July 15), an ant belonging to one of 

 my nests of Formica fusca was out hunting. At 8.8 I 

 put a spoonful of honey before her. She fed till 8.24, 

 when she returned to the nest. Several others were

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