=Cacao.= The production of cacao, which grows wild in the _montaña_, should be greatly increased. The Department of Cuzco produces a particularly fine article with exquisite taste and aroma, which brings a higher price than that of Brazil or Ecuador, though little known outside of the country. In the Perené Valley a plantation of 200,000 trees has been set out. Vast tracts in the Departments of Amazonas and San Martín and in the Province of Jaen are also suited to its growth. =Coca.= The culture of coca is important, but more limited as to future development since its medicinal use should not be greatly increased and its general use not at all. The plant is a shrub, usually six feet high, cultivated in the districts of Otuzco (the most important) and Huamachuco (Libertad), Huanta (Ayacucho), Cuzco, and Huánuco. It grows best in valleys of 3000 to 7000 feet altitude, where the temperature varies from 60° to 85°, in clayey but not marshy ground, with iron but no salt. It needs frequent rains and humidity. Three or four crops may be picked annually, the first in 18 months; the yield continues 40 years. Care is needed in picking the leaves and in drying. A great quantity is consumed by the Indians, and some is exported to Europe and the United States, both as dried leaves for making wines, tonics, etc., and for the extraction of alkaloid; also as cocaine for the making of which over 20 small factories exist in Peru. Chewing coca leaves is of great service on the plateau for necessary and unusual exertion, but injurious and stupefying when its use is continuous. =Rice= is grown in the north in Lambayeque and in the Pacasmayo Valley of Libertad. With one flooding and little ploughing the crops are produced annually, 46,000 tons in 1917. A little is exported but more is imported. The two varieties grown are Carolina and Jamaica. The straw is not utilized. =Fruits= of various kinds may be grown in all the coast valleys, but south of Lima the culture, especially of grapes, is more advanced. Even in poor years it is said that the grape crop is superior to the European average; but too little attention has been paid to improving and extending the industry. The vineyards are small and combined with the other interests of a _hacienda_. The grapes are grown on stocks about eight feet apart, supported first by canes, later by trellises on adobe columns. Nine hundred gallons of wine an acre is an average yield. Italia and Abilla are cultivated for white wines, Quebranta, Moscatel, and others for red; the former of these two being most prolific and generally grown. A pink Italia is a fine table fruit. Wines cheap and good are manufactured to the amount of 2,200,000 gallons yearly, and 770,000 gallons of _pisco_, made from white grapes, also quantities of alcohol. The sugar of the _montaña_ is used to make _aguardiente_ or rum; in several coast districts a finer quality is made from grapes and is probably what in some sections is called _pisco_.
