_4th. Concluding Suggestions_.--Having shown that tea can be grown in the Himalayas, and that it would produce a valuable and remunerative crop, the next great object appears to be the production of superior tea, by means of fine varieties and improved cultivation. It is well known that a variety of the tea plant existed in the southern parts of China from which inferior teas only were made. That, being more easily procured than the fine northern varieties, from which the great mass of the best teas are made, was the variety originally sent to India. From it all those in the Government plantations have sprung. It was to remedy this, and to obtain the best varieties from those districts which furnish the trees of commerce, that induced the Honourable Court of Directors to send me to China in 1848. Another object was to obtain some good manufacturers and implements from the same districts. As the result of this mission, nearly twenty thousand plants from the best black and green tea countries of Central China, have been introduced to the Himalayas. Six first-rate manufacturers, two lead men, and a large supply of implements from the celebrated Hwuy-chow districts were also brought round and safely located on the Government plantations in the hills. A great step has thus been gained towards the objects in view. Much, however, remains still to be done. The new China plants ought to be carefully propagated and distributed over all the plantations; some of them ought also to be given to the zemindars, and more of these fine varieties might be yearly imported from China.
