may, however, be observed constantly returning to 

 the rear : this is probably the means by which the 

 whole army is governed. 



With such dispositions, manoeuvres, and disci 

 pline, Huber saw an army of legionaries set out 

 for a negro city. With their usual impetuosity of 

 attack, one party soon entered, and returned laden 

 with the young of the assailed ant-hill ; a second 

 detachment, not meeting with equal success, sepa-

" The legionaries at first hesitating to approach, 

 rambled about or returned to the rear ; they then on 

 a given signal rushed forward m inasse, with great
