* In four minutes a worker had passed down the incline and laid a pupa upon the top of the nest. 

 For some time it continued to store pupae in that place and was soon joined in the occupation by a few 

 other workers. Later stragglers from the nest carried these pupae into the nest. 



•j- All of the puptB were carried down incline B. A worker ascended incline A to the stage and carried 

 a pupa down incline B to the nest. 



% Two of the pups were conveyed down incline A to the nest, the remainder were carried down 

 incline B. 



° Immediately several workers picked up pupae and started down incline B, but when they reached 

 the gap, they turned around and returned to the stage. 



§ While some were seeking a way home, others were storing pupae under the foot of the incline plane. 

 These pupas were finally taken to the nest. 



** The ants went practically direct from the pile of pupa; to the incline. No pupae were stored under 

 the incline. 



j-j- The workers, one by one, passed unburdened to the nest and left the pupae alone on the stage. 

 Fully eleven minutes elapsed before they returned to the stage and began to carry the pupae home. One 

 worker passed down incline A to the stage and then carried a pupa up incline B to the nest. All of the 

 pupae were carried up incline B, which occupied the same position that had been occupied by the incline 

 along which they had learned the way to the nest. 



tt All of the workers passed, unburdened, to the nest and over thirty minutes elapsed before any 

 worker returned to the stage for pupae. All the pupae were carried down incline A. 



°° The pupae were carried down incline A. All of the work seems to have been done by one worker; 

 the others, after once reaching the nest, remained therein.
