Note lll — BOOK IV.
Reading edition
Swine, and other Animals that dig, have their Noses made more tendinous, callous, and strong for this Service, than others that do not dig. They are also edged with a proper, tough Border, for penetrating and lifting up the Earth; and their Nostrils are placed well, and their Smell is very accurate, to discover whatsoever they pursue by digging.
