 Iv llic'V ciiiiilìcd on lo the eoik and al once slopped, 

 leelini; willi llieir anlennae. Tliey did noi wander about 

 llie lal)le bui alter a Mille liesilation returned to the nest 

 by the same circuitous route along wiiich they had come. 

 1 did noi continue to watch these carefully as my at- 

 tention was taken up by the ants on the cork, but I ob- 

 served that after a few minutes ants ceased to come 

 from the nest. 



Meanwhile the ants on the cork board went on 

 with their woik. I had remoxcd all those ready to return

 these anls came chielly in i^ioups of six to ten so that I 

 wailed till one i^rouj) had just left the l)oard before re-

 were lemoved. 'I'he remaining ants then began their 

 return jouiney to the nesl. and. on reaching tbe s|)ot in the 

 lower cork whence they used to descend to the table, 

 they climbed down as before, but on reaching the table 

 fell aiound with their anlennae without leaving the edge

 with Ihe same result as before; the majority then re- 

 turned U) food carcase while a few wandered about on 

 the corks aimlessly. I watched Ihem for about twenty 

 minutes from this time bui not one retinned to nest and 

 if one ventured on to the table it \'erv soon lelurned to 

 the cork again. 



I was tlien obliged to go oui and on my return two 

 hours later found a fresh palli had been made between 

 the nest and the carcase and work was progressing act-
