Both failures were the result of inability to discriminate. Two leaves and a bud are the aim of the clever f ngers of the underpaid human picker. No machine short of a laser-controlled robot could approach a skilled woman in speed, accuracy, or reliability—as long as the supply of labor continues. One day, perhaps, the picking problem might be solved. If the process were mechanized, a great change could come over the industry. At least 6 American states would be able to produce tea of a high quality, as was once achieved in South Carolina. Only the high cost of picking prevents such a development today. The other 3 candidates for mechanization are withering to 50% moisture, rolling, and drying to 5% moisture. Withering by the use of heated air gives a poorer quality-product, so that during the rainy season air is predried by being passed over silica gel, thus achieving the same result as with hot air but without added temperature. This was a development of the 1930s, but as early as 1850 withering fans were in use in India,
