224 ATTEMPTS TO ASCEETAD* 



Septetrhbe)' 8. — Began at 11 a.m. Up to 3 o'clock 

 only seven ants found their way to the honey, while 

 about as many ran up the other pillars. The arrival of 

 these seven, therefore, was not more than would 

 naturally result from the numbers running about close 

 by. At 3 we allowed the ants then on the honey to 

 return home. The result was that from 3.6, when the 

 first went home, to 3.30, eleven came ; from 3.30 to 4, 

 no less than forty-three. Thus in four hours only seven 

 came, while it was obvious that many would have 

 wished to come, if they had known about the honey^ 

 because in the next three quarters of an hour, when 

 the^y were informed of it, fifty-four came. 



On September 10 I tried the same again, keep- 

 mg as before three ants always on the honey, but not 

 allowing any to go home. From 12 to 5.30, only eight 

 came. Those on the honey were then allowed to take 

 the news home. From 5.30 to 6, four came ; from 

 6 to 6.30, four ; from 6.30 to 7, eight ; from 7.30 to 8, 

 no less than fifty-one. 



On September 23 we did the same again, begin- 

 ning at 11.15. Up to 3.45 nine came. The ants 

 on the honey were then allowed to go home. From 

 4 to 4.30 nine came ; from 4.30 to 5, fifteen ; from 5 

 to 5.30 nineteen ; from 5.30 to 6, thirty-eight. Thus 

 m three and a half hours only nine came; in two, 

 when the ants were permitted to return, eighty-one. 



Again, on September 30 I tried the same arrange- 

 ment, agam beginning at 11. Up to 3.30 seven ants
