tual snow, as the theorists would have it, the banks of the Sutluj 

 river afford pasture for myriads of quadrupeds. The town of 

 Baba is tenanted throughout the year ; at which place, and at 

 Dumpu, fine crops of awa are gathered, a species of grain 

 which the natives consider to be a kind of barley, though Dr. 

 Wallick says, that the sample I sent him, and which is grow- 

 ing freely, appears to be a sort of wheat. The meal it yields 

 IS very fine, and the grain being so hardy may perhaps prove 

 an acquisition in some parts of Great Britain. To an unlearned 

 observer the awa, while in the ear, resembles barley; and 

 when deprived of its husk, wheat. 



A mean of the barometrical observations, by Colonel Hard- 

 wicke, is taken for the day of my observation, the two days 

 preceding, and the two days following : thus,
