From Ohio History Central
The opossum is about as large as a small dog,.' It climbs the trees and sleeps hanging to a branch by its tail, which is bare of hair and quite round. Should one approach it unawares, it never attempts to escape but lies down as dead and makes no motion, though handled and turned. The female has a bag under her belly, in which she carries her young'. The flesh of the creature tastes like pork and is eaten by the English, rarely by the Indians.
