Note 368 — LETTER VI.
Reading edition
The same intelligent gentleman related to me, that a person having taken some land at Bahia in the Brazils, he was compelled by these ants, which were so numerous as to render every effort to destroy them ineffectual, to relinquish the occupation of it. Their nests were excavated to the astonishing depth of fourteen feet. Merian Insect. Sur. 18. Smeathman on Termites, Phil. Trans. lxxi. 39. note 35.
