growing tea. He therefore made a careful survey 

 of the district of Kamaon, selecting sites for fresh 

 nurseries at Bheemtal, and Hawalbagh, and from his 

 report I make the following interesting extract : 



"In selecting land for the new nurseries, I have 

 paid due consideration to the geological structure 

 of the districts, soil, locality, &c., and have selected 

 places similar to those that are considered good loca- 

 lities in China for the Tea plant. The geological 

 structure of the Kemaon province is highly interest-

 the saliferous system, consisting of red and green 

 marl, sandstone, bituminous marl slate, imbedded 

 in the marl ; enormous beds of gypsum or sulphate

 phate of alumina. This rock is of high importance, 

 as from it a vast deal of the alum of commerce is 

 procured. At Kalabaugh, on the banks of the 

 Indus, there are 14 manufactories, with from 12 to 

 18 men in each, engaged in making alum from it: 

 when made, the alum is sold at the manufactory for 

 about Us. 19 per camel load. It is therefore well 

 worthy of the attention of Government, as the alum 

 slate occurs in inexhaustible beds in Kemaon. The 

 saliferous system rests upon a series of clay slates 

 belonging to the transition series; the magnesian 

 limestone, carboniferous and old red sandstone series,
