and is cooped in width. The latitude of Kasan, at our halting place, 

 where the Pen rivulet falls into the Diking, is 27° 30' 25." Between 

 Kasan and Lugo, which was our first stage of land route— the Diking 

 winds in several channels in a stony plain, occasionally meeting the 

 base of the low hills on either side. On the north bank two or three 

 rivulets fall in, the principal of which is the Pa/can. The hills on that 

 side are low near the rivers, and are spotted with patches of cleared 

 grounds ; on the south side they are at first two hundred feet, and gra- 

 dually rise till opposite Lugo they are five or six hundred feet high, and 

 are all clothed in heavy tree jungle. We passed the river twice by fording, 

 though with difficulty, and opposite the little village of Gakhen we had 

 to cross from the south to the north bank in a canoe, and there being but 

 one, we were much delayed. We next ascended to the top of a cliff over- 

 hanging the river, and passed through a few fields and much jungle to 

 Lugo, a village of five or six houses, and thence we descended from the 

 cliff to the mouth of the Tungon Topon rivulet. At this point the plain 

 terminates, and the river is seen to issue from a narrow opening in the 

 north-east. 



From Lugo there are two routes, one over the Insong hill, directly 

 east, which, by disuse, is said to have become nearly impassable ; and ano- 

 ther which was recommended to us, though not so direct, leading over a 

 lower part of the hills, a little more north. The banks of the Diking 

 are said to be impracticable. We went up the Tungon, which is one 

 continued rapid, and after proceeding some distance northward, turned 

 to the east, where the hill is nearly flat, and covered with heavy bamboo 

 jungle. To the north we saw a very high wall of hill connected with 

 Dapha JBJium. 



We passed close to the village of Pishi, and were inclined to halt there 

 where some sort of hut might he had for shelter, but a jealous feeling
