" The carp was originally from Asia, whence it was early introduced into Europe, where it is extensively reared in artificial ponds. Within a few years it has been introduced into America, and widely distributed by the government. Domestication has produced several varieties, as the leather carp, which is nearly or quite destitute of scales, and the mirror carp, which has only a few large scales. Intermediate varieties occur."
