by the mycelium of a fungus (Rozites gongylophora). The 
mycelium is kept aseptically clean — ż.e., free from all other spe- 
cies of fungi and even from bacteria — and induced to grow in 
an abnormal way by bringing forth minute swellings which

constitute the only food of the ant colony. Möller likens these 
swellings to the “ Kohlrabi ” of the German kitchen gardens. 
they had filched from a mill near their nest. Sometimes they prefer to collect 
seeds or young flower-buds. In winter, when the leaves have fallen from a th 
trees except the live oaks and cedars — trees which the Attas avoid, probably 
because the leaves offer too much resistance to their mandibles — they garner the 
young leaves of the sorrel and lupine. At such times, especially when the land- 
scape is flooded with the brilliant Texan sunshine, one may, perhaps, not inap- 
Propriately compare the ant procession with a procession of “ unday-school 
children carrying banners" (McCook, On the Architecture and Habits of the 
Cutting Ant of Texas (Atta fervens), Proc. Acad. Nat. Sci. Phil, pp. 33-49; 
1879).
