12 Journeyings of an Ant. 



here for a lengthened period the ant goes utterly out 

 of sight, lost in the interior, slowly groping round 

 about within, and finally emerging in a glade where 

 your walking-stick, carelessly thrown on the ground, 

 bends back the grass and so throws open a lane to

As this process goes on from morn till night

 difficulties and obstacles before which the task of 

 crossing Africa from sea to sea is a trifle. How, for 

 instance, does the ant manage to keep a tolerably 

 correct course, steering straight despite the turns and 

 labyrinthine involutions of the path? It is never 

 possible .to see far in front half the time not twice 

 its own length ; often and often it is necessary to 

 retrace the trail and strike out a fresh one a step 

 that would confuse most persons even in an English

 of the ploughed field. I say by observation, and the 

 exercise of faculties resembling those of the mind, 

 because I have many times tried the supposed un-

 fore it must possess a power of correcting error which
