Besides the numbered specimens, I have put a number of others into the 

 box, and one or two pieces of sandstone from the hill at Dowlaiswaram, 4 

 miles South of Rajahmundry, which also bears the appearance of being of 

 igneous origin. It is of this the Anicut is constructed. 



Opposite Rajahmundry an extensive range of low hills occurs in the 

 neighbourhood of Paugady the first dak bungalaw on the road to Ellore, 

 the whole of which appears to be of a similar formation to Kateru, I was 

 told that oyster shells had been found there. 



Museum of Economic Geology. — I was applied to by Messrs. Oliva and Co. 

 of Calcutta for information regarding the Peats of Bengal. This informa- 

 tion was desired for some French speculators who are manufacturing turf at 

 home and thought of extending their operations to India. Mr. Daly of 

 the House of Correction obliged me with some of the common peat earth 

 of the jheels, which is extensively used for manure all over the country, and 

 some of the same substance coked, which like the Bog-peat of Ireland Mr. 

 Daly has found to be an excellent fuel ; and also valuable from its de-odoris- 

 ing properties. Being well acquainted with this substance, I read the 

 substance of my reply to Messrs. Oliva's reference, as it contains many facts 

 which are not generally known and are of interest both in a geological and 

 economical point of view. 



" I have had extensive opportunities of being acquainted with this sub- 

 stance, having when a planter, used hundreds, not to say thousands, of tons of 

 it as manure, and dug through thick beds of it down to the bed of the Jheel 

 so as to see it in all its stages.
