In 1776, Sir
Joseph Banks, a British botanist, recommended for the first time that tea cultivation should be taken up in India. Four years later, in 1780,
Robert Kyd, who founded the botanical garden at Kolkata in 1787, started experimenting with tea cultivation in India with consignments of seeds which arrived from China. Decades later, in 1815, Colonel Latter, a British army officer, reported that the Singpho people gathered an indigenous species of tea, and ate its leaves with oil and garlic. In 1820s,
Maniram Dutta Baruah informed the British cultivators—Major Robert Bruce and his brother
Charles Alexander Bruce—about the indigenous tea growing in the jungles of the Nocte and the Singpho countries, which was hitherto unknown to the rest of the world. In or around 1833–34, Namsang and Hukanjuri tea gardens were taken up by the British on account of the indigenous tea growing on them. The land belonged to the Namsang Chief and was also claimed by the Borduria Chief. These gardens became operational from October 1840. The gardens are now under Assam's Jeypore area of
Dibrugarh district. Teams of wild elephants were harnessed to clear the dense forest, toppling trees with a girth of 25 feet. In 1838, India's first twelve chests of manufactured tea, made from the indigenous tea, were shipped to London and were sold at the London auctions. This paved the way for the formation of the Bengal Tea Association in Kolkata and the first joint stock tea company, the Assam Company, in London. Ironically, the native plants flourished, while the Chinese seedlings struggled to survive in the intense Assam heat and it was eventually decided to make subsequent plantings with seedlings from the native tea bush. The people from Namsang and Borduria worked willingly for the company and were paid in kind, and the Chiefs received "douceurs" from the Managers of the Assam Company. About the year 1861–62, these gardens were transferred to the Northern Assam Company, and the Namsang Chief was taken to Nazira for the purpose of being informed that the lands were about to be transferred to other proprietors. He received a further "douceur" of Rs. 1,000 and presents; and "from that time to the present (1873), owing to his power to retain possession as against the Borduria Chief, he has been undoubtedly recognized as the landlord." These gardens were the subject of correspondence between the Government of British India and the Bengal Government. At that time, the present-day Northeast India was under the Bengal Government. As per a 1876 report, ever since the gardens were transferred to the Assam Company on the relinquishment of the government undertaking, the Assam Company paid yearly subsidies of Rs. 200-250 each to the Chief. The gardens changed hands often, but the owners always continued to pay the subsidy till 1873, when a Mr. Minto was the owner. About this time, the Namsang Chief was reported to have assumed a threatening attitude in connection with the gardens, and on Mr. Minto's representations to the contrary, the anomalous position of the gardens came to light. After two years of negotiation, the Namsang Chief and the Government of British India reached an agreement, and the latter sanctioned this settlement,---
vide letter No. 1943P., dated 6 July 1875. The terms of agreement were: 1. That the Namsang Chief shall receive an annual subsidy of Rs. 450 for ever---this being the sum Mr. Minto paid to them. 2. That this payment shall cover claims not only in respect of the tea gardens of Hukanjuri and Namsang, but of all the tract of country which will come within the "Inner Line," and over which the Namsangias have hitherto asserted rights. 3. The Namsang Chief was also granted a license for obtaining arms and ammunition. ==Historical books==
