TOBACCO IN THE PHILIPPINES.

easily cultivated and in good physical condition. Small areas of loam or heavier soil are found in several places; but these are usually low depressions, where flood waters accumulate and stand long, thus allowing the fine particles of clay carried in suspension to settle on the surface of the ground. The lands cultivated to tobacco are the bottoms or lands subject to floods from the high waters of the Cagayan Eiver. Once or twice during the rainy season these lowlands are flooded to the depth of several feet by water carrying in suspension considerable quantities of fine sediment rich in fertilizing matter which, on standing, is deposited on the surface of the soil. No artificial fertilizer is used on the tobacco lands, and plants are entirely dependent on the fertilizing action of floods to supply the necessary amounts of the elements of fertility.

While the amount of fertilizing matter annually furnished these soils by the overflows of the Cagayan River is considerable, there is no doubt that with the aid of fertilizers much better results would be obtained.

Growing Tobacco under Shade.

In the province of Isabela one hectare of land was devoted this year (1903-1904) by one of the tobacco companies to an experiment in growing tobacco under shade. The construction of the shade was the same in all essential particulars as that commonly used in the Connecticut Valley and in Florida for growing fine-grade Sumatra tobacco, except that bamboo and bejuco (rattan) were substituted for hard-wood posts and nails. Owing to unavoidable delays, the field was planted too late in the season to obtain a representative result this year. It was observed, however, that the plants under shade were not attacked by insects and had broader, finer and darker-colored leaves than the plants outside. The superintendent in charge of the work expressed himself as convinced of the practicability of this method for producing a fine grade of tobacco for wrapping purposes. The Insular Bureau of Agriculture will conduct an experiment the coming season in growing Sumatra tobacco under shade.

Methods of Cultivation in Use.

The first operation in growing tobacco is the preparation of the seed-bed. This the native usually makes near his house, or preferably, in some cleared piece of ground in the woods near by. New or virgin soil is preferred, so that the young plants can have a vigorous growth and be in suitable condition for transplanting. Any brush and stumps that may be on the land are gathered and burned until entirely reduced to ashes. The ground is then stirred with the native plow or with an iron bar having a flattened end with a sharp edge.
