The only horned cattle said to be fit for work in Jamaica are those which have a great deal of black in them. The white are terribly tormented by the insects, and they are weak and sluggish in proportion to the quantity of white. On the contrary, I am told that such a thing as a black horse is not to be found in the island ; those which may be imported black soon change their colour into bay; and colts are said to have been dropped perfectly black, which afterwards grew lighter and lighter till they arrived at being perfectly white.
