It is in the rice fields, however, that the buffalo excels. Rice is not sown broadcast; it is first planted in nurseries, and when about 12 inches high is transplanted a spear at a time into the soft mud of the fields which has been prepared by ploughing. In preparing the ground for the rice, no animal is equal to the buffalo, for in the mud and water of the field it is in its element. Its great weight causes it to sink deep in the mud and its enormous strength enables it to plough deeper than can be done in any other manner.
