98 Instinct. 



great diversity of building as is seen especially 

 among bees of different kinds ; as the Honey-bee 

 with its waxen wonder and the Bumble-bee with 

 her few uncouth cells, chiefly the deserted cocoons 

 of her brood. The Carpenter-bee and others give 

 still more diverse methods. Among the wasp tribe 

 we find those that build with woody fiber and 

 others that build with clay. And both of these 

 materials are wrought into varied forms by differ- 

 ent species of the wasp tribe. 



3. The building is sometimes the work of the 

 male alone, as in the case of the Sticklebacks among 

 fishes ; and sometimes of the female alone, as the 

 nest of the Paper-wasp prepared for the first brood 

 of workers in the spring ; and sometimes it is the 

 joint labor of both male and female, as among most 

 birds. 



And then in other cases, all the care of building 

 belongs to a set of workers that never produce 

 young themselves but seem to have their whole en- 

 ergy concentrated on the work of providing for and 

 defending the young of others. The White-ants 

 and Honey-bees are the best examples of such 

 builders. 



4. Those animals that show the greatest range 

 of building power are those that build in the rudest 

 manner ; and those animals that attract the great- 

 est attention by their complicated and skilfuly 

 constructed homes, are those that work almost with 

 the exactness of machinery.
