hole in the swamp; evidently they now and 
then got a whiff from our camp, for they 
were continually lifting and curling their 
trunks. To see if by any chance there was 
a bull among them we moved them out of 
the swamp by shouting; the wind blew 
hard and as they moved they evidently 
smelled the camp strongly, for all their 
trunks went into the air; and off they 
went at a rapid pace, half of the herons 
riding on them, while the others hovered 
over and alongside, like a white cloud. 
Two days later the same herd again made 
its appearance. 
Spur-winged plover were nesting near 
camp, and evidently distrusted the car¬ 
rion feeders, for they attacked and drove 
off every kite or vulture that crossed what 
they considered the prohibited zone. They 
also harassed the marabous, but with more 
circumspection; for the big storks were 
short-tempered, and rather daunted the 
spur-wings by the way they opened their 
enormous beaks at them. The fish eagles 
fed exclusively on fish, as far as we could 
tell, and there were piles of fish bones 
and heads under their favorite perches. 
Once I saw one plunge into the water, 
but it failed to catch anything. Another 
time, suddenly, and seemingly in mere mis¬ 
chief, one attacked a purple heron which 
was standing on a mud bank. The eagle 
swooped down from a tree and knocked 
over the heron; and when the astonished 
heron struggled to its feet and attempted to 
fly off, the eagle made another swoop and 
this time knocked it into the water. The 
heron then edged into the papyrus, and the 
eagle paid it no further attention. 
In this camp we had to watch the white 
ants, which strove to devour everything. 
They are nocturnal, and work in the day¬ 
time only under the tunnels of earth which 
they build over the surface of the box, or 
whatever else it is, that they are devour¬ 
ing; they eat out everything, leaving this 
outside shell of earth. We also saw a long 
column of the dreaded driver ants. These 
are carnivorous; I have seen both red and 
black species; they kill every living thing in 
their path, and I have known them at night 
drive all the men in a camp out into the 
jungle to fight the mosquitoes unprotected 
until day-light. On another occasion, where
