mention is several times made of “ deserted ant-hills.”” Further 
investigation has shown that these hills are formed by loose 
earth brought by these ants out of their subterranean exca- 
vations. These consist of oblique tubes, some eight or nine 
inches wide, others only half an inch in diameter; they 
sometimes reach a depth of thirty or forty feet. In the 
greatest depth are their granaries, containing often many 
bushels, and it is said, even wagon-loads, of corn and other 
grain. These ants are also common about New Braunfels, 
and this or another species has occasionally been found to 
be quite destructive to Mr. Lindheimer’s collections.”
