22 SECRETS OF ANIMAL LIFE 
seven, when Professor Emery’s son stopped count- 
ing. It seems likely that the Amazons are moved 
by an instinctive restlessness, which becomes peri- 
odically irrepressible, and leads to the impetuous 
raids, which, by the way, are almost invariably 
confined to the afternoon. 
In 1914 the veteran observer made a study of a 
flitting from one nest to another. On the first 
afternoon the Amazons were seen carrying their 
slaves, sometimes in contradictory fashion in 
opposite directions; but after that the slaves did 
most of the work of transporting the young, and 
even carried their mistresses. On another occasion 
Emery saw an unusual sight, perhaps a mutiny, 
but more probably a madness. Several slaves 
attacked an Amazon and began to pull her about; 
she slew two of them forthwith, but was soon 
afterwards attacked by another Amazon, and there 
ensued a quarrel fatal to both. Next day the slaves 
were seen carrying off the two bodies. 
Like Huber and Forel before him, Emery puzzled 
over the resistance that the auxiliaries often offer 
to the issue of an expedition of Amazons. Forel 
suggested that the young auxiliaries, brought in 
from outside, have to become accustomed to the 
strange proceedings before they can acquiesce in 
raids as part of the order of the day. Emery 
suggests, however, that there is something subtler— 
namely, “a myrmecophilous relation ’”’—that the 
servants hold their mistresses as something like 
wayward pets. He admits, however, that in the
