Buffaloes, however, more than other domestic animals, are subject to an epidemic disease, the symptoms and nature of which have not been hitherto carefully noted, or satisfactorily explained. It prevails throughout the whole island, and generally re-appears after an interval of three, four, or five years: it makes great ravages in the stock of the peasantry, and is checked in its progress by no remedies which have hitherto been discovered or applied: it is of an infectious nature, and excites great alarm when it appears: it bears different names in different parts of the island. As the bull and cow are not liable to this disease; and as, in addition to this advantage, they are less expensive in their original purchase, they are preferred by many of the natives. For draught, the buffalo and cow are employed; and for burden, the horse (particularly mares) and the ox. In level districts, and in good roads, the use of the latter is preferred. The usual burden of a horse is rather less than three hundred weight, and that of an ox rather more than four; but in mountainous districts, and where the roads are neglected, one half of this weight is considered as a sufficient, if not an excessive load. The comparatively higher price of cattle on Java than in Bengal has been accounted for from the demand for them as food, and the absence of extensive commons on which to feed them. When implements of husbandry are mentioned in British agriculture, many expensive instruments, and complicated machinery suggest themselves to those acquainted with its practical details. From the preparation of the ground for receiving the seed, till the grain comes into the hands of the miller, labour is economized and produce increased, by many ingenious processes and artful contrivances, of which a Javan could form no conception. He could form no idea of the fabrication or advantages of our different kinds of ploughs; of our swing ploughs, our wheel ploughs, and our two-furrow ploughs; of our grubbers, cultivators, and other instruments for pulverizing the soil; of our threshing and winnowing machines, and other inventions. A plough of the simplest construction, a harrow, or rather rake, and sometimes a roller, with a _páchul_, or hoe, which answers the purpose of a spade; an _árit_, which serves as a knife or small hatchet; and the _áni áni_, a peculiar instrument used by the reapers, are all the implements employed by him in husbandry; and the total cost of the whole does not exceed three or four rupees, or from seven to ten shillings.
