 their bodies close to the ground, but this ant runs, and 

 with its body well elevated above the surface. It differs 

 from most other ants also in this : it makes its nest 

 in the ground, but passes nearly all its existence on a

I came on these ants this morning quite by accident. 

 I was sauntering down one of the paths of the garden,
