parently lacking any definite concerted action. 
At six o’clock the following morning I started 
out for a swim, when at the foot of the laboratory 
steps I saw a swiftly-moving, broad line of army 
ants on safari, passing through the compound to 
the beach. I traced them back under the ser- 
vants’ quarters, through two clumps of bamboos 
to the out-house. Later I followed along the 
column down to the river sand, through a dense 
mass of underbrush, through a hollow log, up the 
bank, back through light jungle—to the out- 
house again, and on a large fallen log, a few feet 
beyond the spot where their nest had been, the 
ends of the circle actually came together! It 
was the most astonishing thing, and I had to 
verify it again and again before I could believe 
the evidence of my eyes. It was a strong column, 
six lines wide in many places, and the ants fully 
believed that they were on their way to a new 
home, for most were carrying eggs or larve, al- 
though many had food, including the larve of 
the Painted Nest Wasplets. For an hour at 
noon during heavy rain, the column weakened 
and almost disappeared, but when the sun re- 
turned, the lines rejoined, and the revolution of 
the vicious circle continued.
