WARS OF WHITE ANTS. 333 



sandsj nay, millions, seem employed, yet they never 

 embarrass one another. While the labourers are 

 thus engaged, the soldiers retire, save here and 

 there one who saunters about, never touching the 

 mortar. One in particular places itself close to the 

 part undergoing repair ; it may be seen turning lei-
