Mr. CoLEBROORE ow the Valley of the Sutluj River. 127 



The general inclination of the strata is stated to be ten or fifteen degrees, and 

 tlie direction much diversified. 



At Jauri^ on the northern bank of the Sutluj, in the vicinity of the places 

 above mentioned, or nearly half way between them, hot springs issue at so 

 small a distance as two or three feet from the river. They are eight or ten in 

 number. A thermometer plunged into one of them rose to 130^° Fahr., 

 while the temperature of the river was 61° on the 11th of October. The water 

 bubbles up among small pebbles, has a strong sulphureous smell and very dis- 

 agreeable brackish taste, and encrusts the stones with a yellow substance 

 (Qu. sulphur?). 



Gold-dust is found in small quantities, among the sands of the river, near 

 this place. 



The next specimens for notice are from the Gisiganga, a stream tributary 

 to the Jamuna. The banks of that river for many miles, between Kurla and 

 Sermur, consist of limestone, and of a rock containing chlorite and mica. The 

 bed of the river in that part has an elevation of 1500 to 2000 feet above the 

 sea. 



Among the specimens is a stalactite, from the roof of a cave near the top of 

 the Carol mountain. The cavern is situated about 6500 feet above the sea. 

 Mr. J. B. Fraser likewise, in the narrative of his journey through the Hima- 

 laya mountains*, has noticed the Sein range of hills, on the right bank of the 

 Giriganga, as formed of calcareous stone. 



It appears then, that limestone is prevalent in the lower hills, which adjoin 

 to the Himalaya, and are contiguous to the lower valley of the Sutluj. 



From the valley of the Paber river, another tributary of the Jamuna, speci- 

 mens have been furnished. One from the banks of that river, near Cshirgaon, 

 at an elevation of 6000 feet above the sea : it is. gneiss. Another is from the 

 confluence of the Paber and Sisiin rivers, at an elevation of 8350 feet above 

 the sea. The rock consists of gneiss. 



Lieut. Gerard crossed the Himalaya at the Bruang pass, to enter the middle 

 valley of the Sutluj. It is the route of communication between this valley 

 and that of the Paber. Its extreme altitude is 1 5, 100 feet above the sea. A 

 variety of specimens was collected at this pass. They consist of mica-slate, 

 gneiss and granite; some of them containing garnets; others tourmalin. 

 Veins occur of quartz and mica, and of quartz and hornblende. 



The travellers proceeded along the left bank of the Sutluj to Puan and 

 Rispe, at which last-mentioned place they met Lama priests. Thence they
