"As the tea shrub," says M. Guillemin, "is grown in several plantations about two days' journey distant from Rio, in different directions, I hired a lodging at St. Theresa, sufficiently contiguous to all the establishments I meant to visit, and further recommended by having a small garden attached to the house, where I could deposit the growing plants of tea, and sow seeds. During the month of November, except when hindered by slight indispositions incidental to the Brazilian climate, I pursued my researches, and principally in the charming valleys of the Tijuka and Gavia mountains. There, together with coffee, their principal product, the most valuable plants of the equatorial region are cultivated. In the middle of November I had an opportunity of observing the method pursued when culling the tea, which is performed by black slaves, chiefly women and children. They carefully selected the tenderest and pale-green leaves, nipping off with their nails the young leaf bud, just below where the first or second leaf was unfolded. One whole field had already undergone this operation; nothing but tea shrubs stripped of their foliage remained. The inspector assured me that the plant received no injury from this process, and that the harvest of leaves was to become permanent by carefully regulating it, so that the foliage should have grown again on the first stripped shrubs at the period when the leaves of the last plant were pulled off. About 12,000 tea shrubs are grown in this garden: they are regularly planted in quincunxes, and stand about one metre distant from each other; the greater number are stunted and shabby looking, probably owing to the aspect of the ground, which _lies low, on the level of the sea, and exposed to the full rays of a burning sun_; perhaps the quality of the soil may have something to do with it, though this is apparently similar to what prevails in the province of Rio Janeiro. This soil, which is highly argillaceous, and strongly tinged with tritoxyde of iron, is formed by the decomposition of gneiss or granite rocks. The flat situation of this tea ground is unfavorable to the improvement of the soil, for the heavy rains which wash away the superfluous sand from slanting situations, of course only consolidate more strongly the remaining component parts, where the land lies perfectly level, and thus the tea plants suffer from this state of soil.
