Part I.—Geology. Crossing the numerous rivei^ from the Ganges to the Brapia- putra, at Jumalpore, we observed to the eastward an insulated tract of high land, between the towns of Moodapore and Puc- culoe. It is laid down on the map of Bengal, as midway between Jumalpore and Dacca. This elevated tract, is, I have no doubt, an important geological feature; and I regretted thatnjur duty did not allow of my remaining to examine it. On approaching the Brarnaputra near Jumalpore, I found the current had gradually forced its way through a yellow clay, or Kanka, that formerly controlled the course of the stream, di- recting it past the N.E. side of the high land above noticed.
