considerable than had been supposed. As the external boundaries 

 towards the Tippera hills, Kachar, and the Kasia mountains have been 

 traced, and the outline is only incomplete on the western side, on which 

 it is not likely any material difference from the old delineation would 

 be discovered, it is likely that the contents (4500 square miles,) now 

 assigned for it, is pretty near the truth. The quarter in which the 

 most considerable error has been found in the old map is the southern, 

 which Rennell does not seem to have visited ; and here many of his 

 positions have been found from ten to forty miles too much to the 

 north. The topography too of this part has been amended, the chains 

 of hills, or rather ridges, having been ascertained to consist of several 

 parallel ranges, separated by wide and fertile vallies, and ranging north 

 and south, instead of east and west, as before supposed. Some of these 

 ridges also are found to be partly in Sylhet, and partly in Tippera, 

 Slid in two or three instances they penetrate deeply into the former 

 district. 



On the side of Kachar, the boundary of Sylhet has been traced south- 

 ward to Chatrchura, a conical peak on the Banka range of hills, the 

 country about which is frequented by the Pytu Kukis, a wild wandering 

 tribe, who migrate from this their north-west limit, eastward to Tung- 

 hum, and southward to an unknown extent, their cognate tribes being 

 found in the neighbourhood of Chittagong. 



In Lower Kachar a complete survey of the cultivated tracts has been 

 effected, the principal rivers traced, and in particular the course of the 

 Delaseri from the southward, followed through a part which heretofore 

 presented only a blank in the map. This tracing, was, however, 

 executed by one of my native surveyors, after circumstances had put 

 it out of my power to conduct it myself. 



Captain Pemberton's surveys in Manipur fix the eastern boundary 

 of Kachar, but points of junction between our surveys occur at Aquee, 

 in the Naga Hills, and on the Bohman range. 



In Upper Kachar a line has been traced along the Jatingah river 

 to its source, and thence to a point on the Di-yung, at which it be- 

 comes navigable for small boats, beyond which I had no opportunity of 

 proceeding northward, but the remainder of the route into Assam was 

 explored by Captain Jenkins, whose valuable Report illustrates the 

 whole of this country. The survey, however, in this quarter was
