Note 3 — XIV

The harvest.A ganta of rice is sufficient to plant four topones (1 topon = 1 loan); from which 100 manojos (bundles) are gathered, each of which yields half a ganta of rice. The old ganta of Naga, however, being equal to a modern ganta and a half, the produce may be calculated at 75 cavanes per quiñon, about 9¾ bushels per acre.3 In books 250 cavanes are usually stated to be the average produce of a quiñon; but that is an exaggeration. The fertility of the fields certainly varies very much; but, when it is considered that the land in the Philippines is never fertilized, but depends, for the maintenance of its vitality, exclusively upon the overflowing of the mud which is washed down from the mountains, it may be believed that the first numbers better express the true average. In Java the harvest, in many provinces, amounts to only 50 cavanes per quiñon; in some, indeed, to three times this amount; and in China, with the most careful culture and abundant manure, to 180 cabanes.4 Sweet potatoes. Besides rice, they cultivate the camote (sweet potato, Convolvulus batatas). This flourishes like a weed; indeed, it is sometimes planted for the purpose of eradicating the weeds from soil intended for coffee or cacao. It spreads out into a thick carpet, and is an inexhaustible storehouse to its owner, who, the whole year through, can supply his wants from his field. Gabi (Caladium), Ubi (Dioscorea), maize, and other kinds of grain, are likewise cultivated.
