Correspondence. 555 



I have sent a box of insects to you by Colonel Seymour, and was 

 collecting away at a great rate, but this order puts a stop to all opera- 

 tions, until we get some arrangements made as to carriage. 



I shall have an opportunity on the march of giving you a rough 

 sketch of the geology of the country we pass through. I shall send 

 you some fishes, &c. &c. before I leave this. 



From the same, on the march from Neemuch to Ferozpore. 



" Nyagong is 9 miles from Neemuch NNW. the whole is clay slate 

 overlying hard basaltic rock, except at one place called the Stony Ghat, 

 which is composed of a soft clayey shale, containing large round nodules 

 of a crystallised rock, very similar to gniess, from three inches to a foot in 

 diameter ; they are so loosely bound in the shale that the whole surface 

 of the ground is covered with them. The whole so much resembled 

 the Cromarty fish beds, that I broke a great number of these nodules, 

 in hopes of finding some organisms, but found none. It appears as if it 

 might have been formed by the vomiting of a volcano sending forth mud 

 and water, and masses of melted rock falling therein. 17th October. — 

 Mungrowl, 13 miles NNE. clay slate. 18th., Chittore, 14 miles north — 

 clay slate running nearly north and south, the dip near the hills 

 being from 45° to 60° ; long lines of it in this position, run along the 

 road, resembling a pavement formed of slates upon their edges. 



The rock on which the fort of Chittore is built, is quartz and horn- 

 stone, the clay slate on the west side of the rock dipping to the west, 

 that on the east to the east ; the rock rises precipitously 400 feet above 

 the surrounding plain. 20th October. — Puttowlee, 6 miles N. by W. clay 

 slate, small hillocks of quartz shooting through it here and there. 21st. — 

 Soonera 13 miles, rock same as last, N. by E. 22nd. — Mundapeeah 9 miles ; 

 N. by E. the clay slate becoming micaceous. 23rd. — Bheelwarrah 6 miles, 

 the mica slate appears generally on this march, and its direction is at 

 right angles to the direction of the clay slate, the dip is very variable. 

 24th. — Mhowah 9 miles N. by E. all deep sand. 25th. — Shahpoora 16 miles 

 NNE. deep sandy soil, the hillocks about are of quartz in some places, 

 containing particles of hornblende, which has been used in building 

 some of the temples, and resembles white marble. 27th. — Khodera 15 

 miles N.by E. ; soil deep, sandy, the rock granitic; all traces of clay and 

 mica slate have disappeared. 28th. — Kekroe 14 miles NNE. deep sandy 

 soil, with a small quantity of clay. 29th. — Deogongl3 miles NNE. in the 

 bed of a river, some miles from camp large masses of sienite, the rest 

 is all deep sand, seemingly disintegrated sienite. 30th. — Malpoorah 13
