When the leaves have been thus twisted and rolled, they are replaced in the great iron pan, and the temperature raised till the hand can no longer bear the heat at the bottom. For upwards of an hour the negroes are then constantly employed in separating, shaking, and throwing the foliage up and down, in order to facilitate the dessication, and much neatness and quickness of hand were requisite, that the manipulators might neither burn themselves nor allow the masses of leaves to adhere to the hot bottom of the pan. It is easy to see that, if the pan was placed within another pan filled with boiling water, and the leaves were stirred with an iron spatula, much trouble might be obviated. Still, the rolling and drying of the leaves were successfully performed; they became more and more crisp, and preserved their twisted shape, except some few which seemed too old and coriaceous to submit to be rolled up. The tea was then placed on a sieve, with wide apertures of regular sizes, and formed of flat strips of bamboo. The best rolled leaves, produced from the tips of the buds and the tenderest leaves, passed through this sieve, and were subsequently fanned, in order to separate any unrolled fragments which might have passed through them; this produce was called _Imperial_, or _Uchim Tea_. It was again laid in the pan till it acquired the leaden grey tint, which proved its perfect dryness, and any defective leaf which had escaped the winnowing and sifting was picked out by hand. The residue, which was left from the first fanning, was submitted to all the operations of winnowing, sifting, and scorching, and it then afforded the _Fine Hyson Tea_ of commerce; while the same operations performed on the residuum of it yielded the _Common Hyson_; and the refuse of the third quality again afforded the _Coarse Hyson_.--Finally, the broken and unrolled foliage, which were rejected in the last sittings, furnish what is called _Family Tea_, and the better kind of which is called _Chato_, and the inferior _Chuto_. The latter sort is never sold, but kept for consumption in the families of the growers. Such is the mode of preparation pursued at Rio Janeiro, though I must add that the process employed at the Botanic Garden being most carefully performed in order to serve as a model for private cultivators of tea, the produce is superior to the generality, so that we dare not judge of all Brazilian tea by what is raised at the garden of Rio. I was also assured, that at Saint Paul each grower had his own peculiar method, influencing materially the quality of the tea, which decided me to visit that province, where I hoped to gain valuable information respecting the culture and fabrication of tea, especially considered as an article of commerce.
