310 Insect Architecture. 



grain-bearing grass mentioned above is intentionally planted. 

 In farmer-like manner the ground upon which it stands is 

 carefully divested of all other grasses and weeds during the 

 time it is growing. When it is ripe, the grain is taken care 

 of, the dry stubble cut away and carried off, the paved area 

 being left unencumbered until the ensuing autumn, when the 

 same ant-rice reappears within the same circle, and receives 

 the same agricultural attention as was bestowed upon the 

 previous crop and so on, year after year, as I know to be 

 the case, in all situations where the ants' settlements are 

 protected from granivorous animals."

 took special care not to invent a theory and to twist facts in 

 accordance with it, but watched the entire proceedings of the 

 insects for a series of years.
