218 DARWINISM STATED BY DARWIN HIMSELF. 



cate information to each other, and several unite for 

 the same work, or for games of play. They recognize 

 their fellow -ants after months of absence, and feel 

 sympathy for each other. They build great edifices, 

 keep them clean, close the doors in the evening, and 

 post sentries. They make roads as well as tunnels under 

 rivers, and temporary bridges over them, by clinging 

 together. They collect food for the community, and, 

 when an object, too large for entrance, is brought to the 

 nest, they enlarge the door, and afterward build it up 

 again. They store up seeds, of which they prevent the 

 germination, and which, if damp, are brought up to the 

 surface to dry. They keep aphides and other insects as 

 milch-cows. They go out to battle in regular bands, and 

 freely sacrifice their lives for the common weal. They 

 emigrate according to a preconcerted plan. They cap- 

 ture slaves. They move the eggs of their aphides, as 

 well as their own eggs and cocoons, into warm parts of 

 the nest, in order that they may be quickly hatched ; 

 and endless similar facts could be given. On the whole, 

 the difference in mental power between an ant and a coc- 

 cus is immense ; yet no one has ever dreamed of placing 

 these insects in distinct classes, much less in distinct 

 kingdoms. No doubt the difference is bridged over by 

 other insects ; and this is not the case with man and the 

 higher apes. But we have every reason to believe that 

 the breaks in the series are simply the results of many 

 forms having become extinct.
