Of the Yo or Yau country, lying along the river of that name, between the barren Tangyi hills that line the Irawdi, opposite Pagan and the base of the Aracan Yoma-doung, nothing more is known. I am sorry to say, than was recorded long ago by Dr. Buchanan. The people are believed to be of the same race with the Burmese, but, from their secluded position, speak the language in a peculiar dialect. There are paths from the Yau country into the Kaldan valley in Aracan, which King Tharawadi made some talk of rendering passable for troops, when he was breathing war in 1839. They must traverse the country of some of the wildest tribes of the Yuma, and nothing of them is known. The Yaus are great traders, and are the chief peddlers and carriers of northern Burma.
