It remains only to mention that, some difference of opinion existing as to the boundary line between Assam and the Burmese territory, it was deemed expedient to define the limits of both countries by a special mission to the disputed point; and for this purpose, in 1837, Dr. Bayfield was deputed to proceed from Ava and join the Burmese Governor of Mogaum, and in the presence of Major White, Political Agent of Upper Assam, to settle the question. Major White, accompanied by Dr. Griffiths, Captain Hannay, and Lieut. Bigge, and the neighbouring native chiefs, with ninety followers, accordingly set out from Namroop Pathar, on the 19th February; and on the 25th of the same month they reached Yaoung Sang Nullah, on the north face of the Patkoe boundary, or range, where the Burmese governor had agreed that the conference should take place. In this dreary wilderness of hills and jungle, the impossibility of obtaining an adequate supply of provisions for ninety persons (the commissariat being carried from the plains of Assam) presented an insuperable obstacle to the prolonged stay of the party with Major White. Having therefore waited till the 5th March, daily expecting the arrival of the Burmese Governor and Dr. Bayfield; and the whole of their provisions being consumed, with the exception of a bare sufficiency for the wants of the party on their return, the Major was constrained to retrace his steps to Suddeah. Captain Hannay, however, pushed on unencumbered, in company with Dr. Griffiths (deputed for scientific purposes to Ava), hoping to meet the Burmese Governor and accomplish the object of the mission: which he did.
