The varieties of ducks are almost innumerable. Main describes 31, and some naturalists number over 100. Besides the black duck above described, several others, as the light gray, the white duck, and some of the tufted, are prolific, hardy, and profitable.
We omit further notice of other varieties; and of the swan, brant, pigeons, &c., as not profitable for general rearing, and only suited to ornamental grounds.
