HIS INTELLIGENCE 87 
Again they ran around the other side, scraped 
away more sand, and tried it once more. They 
kept up this work for half an hour, but did not 
succeed in stirring the great fish. 
At this time the man, who had hidden himself 
to watch them, saw another bird coming. The 
two little workers greeted him with joyful cries, 
to which he replied in the same tones. Then 
all three set to work on the heavy fish. They 
dug more sand out from the lower side, and 
then pushed against the upper side with all their 
strength. They lifted it a few inches, but it 
fell back. 
At last, after resting a few minutes, without 
moving from their places, they worked it in this 
way. They rested their breasts on the sand, 
put their beaks under, and lifted. When the 
fish was raised several inches, they held it with 
their beaks and pushed their breasts against it, 
when over it went, down the little pitch they 
had made. 
They could not stop, and they went with it, 
but at once came back and found enough to pay 
them for their hard work. 
One who really watches birds to see what 
they are doing will see many actions that show 
intelligence and reason.
