124 TKEATMENT OF STKANGEES. 



did not drag nor apparently guide her ; but she went 

 with the rest freely. This I repeated several times 

 with the same result. 



I then took four ants, two from a nest about 500 

 yards from the first in one direction, the other from an 

 equal distance in another. In all cases the result was 

 the same. I then got a few from a colony about half a 

 mile ofif. These also were most amicably received, and 

 in every case tlie stranger went of her own accord to 

 the nest. One of the strangers was, indeed, dragged

 then left free and might have run away if she had 

 liked. She, however, after wandering about for half a

 This, I suppose, can only have been by scent ; and cer- 

 tainly no hounds in full cry could have pursued their 

 game more directly or with less hesitation. In other 

 cases, however, they were much longer before they went 

 in. To satisfy myself that these facts were not owing

 not feel sure about it; but in no case were the ants killed. 



The following fact surprised me still more. I put 

 an ant (Aug. 13) at 9 a.m. on a spot where a number of
