pupas and larva?, and rarely one passed with a 

 bunch of small white eggs. Several black queens 

 came out of the nest, and as they emerged were 

 set upon by red ants, which tried to hold them by 

 their wings. They managed, however, to throw 

 off their assailants, and ran under my feet, where 

 they were followed by a score of black workers, 

 all of whom crowded under the soles of my shoes 

 as I stood on the loose gravel. At noon I timed 

 the ants and found that, on the average, forty 

 pupae and larvas were carried past a given point 

 every minute. Two unbroken columns now ex- 

 tended the entire distance between the nests, one 

 advancing and the other returning. 



Occasionally one passed carrying a portion of a 

 black ant, a head and thorax, or an abdomen. 

 Again, one would appear witfi a live black, which, 

 when liberated by me, frantically made her escape. 

 Very young negroes when carried off were never 

 injured. On one occasion several red ants were 

 struggling with a black, and among them was a 

 black who fought against her own friend. This 

 is the only case in which I saw a black ant help 

 the enemy in this way a traitor, evidently, but 

 presumably one whose pupa had been captured
