NATURE NOTES 
and often seize the carelessly placed grain, and carry it up over 
the ridge, and far down the other slope. When the danger is 
safely overcome, the busy little creature hurries back into the 
nest and doubtless does not fail to pick out the delinquent and 
give him a “ dressing down.” 
These evidences of fallibility and infallibility, of efforts to 
shrink hard work and efforts to correct mistakes and short- 
comings, seem to me the most convincing proof of the possession 
of a degree of intelligence far superior to the automatic instinct 
that many people avow is the only power governing the doings 
of insects. 
The whole ant family contains engineers, warriors, adminis- 
trators and inventors ; equal in their own little world (which 
doubtless seems to them as great and unrivalled as our Empire 
seems to us) to those great men whose statues grace our cities, 
and whose names are handed down to posterity.
