The cultivation of the tea-plant has been introduced into the United States, and those planters who have tried the experiment have succeeded beyond their highest expectations. Dr. Junius Smith had successfully cultivated the plant on his property called Golden grove, near Grenville, in South Carolina. His plants were in full blossom, and as healthy and flourishing as those of China at the same stage of growth. Everything connected with them looked favorable, and Dr. Smith felt abundantly encouraged to extend the culture of the several descriptions of tea upon his property. It is stated that his expectations were so great, that he contemplated to place fresh tea on the tea-tables of England and Paris in twenty days, from the plantation. He had a large supply of plants, and tea seed enough for a million more. The black descriptions blossomed earlier than the green plant, but the latter also blossomed luxuriantly. He introduced at first about 500 plants of from five to seven years' growth, overland from the north-west provinces of India, and some from China direct. In the close of 1849, he writes me:-- "During the past year the tea-plant under my care has passed through severe trials, from the injury received in transplanting, from the heat generated in the packing-cases, from the want of shelter during the severe frosts of February, from the excessive heat in June, and from the drought of 58 days' continuance in July and August. The plants were divested of their leaves and generally of their branches and twigs in February, during my absence in New York. Knowing that the plants were tender, and not fortified by age and mature growth against severe weather, I had directed them to be covered in case a material change of temperature should occur. But these orders were neglected, and they consequently suffered from that cause. The plant is sufficiently hardy to resist any weather occurring in this part of the country, when seasoned for one year.
