Earthenware. 599 



Stoneware. The Delhi clay No. 3, seems to have been hitherto 

 unexamined by any one ; I may be wrong in saying this, but I have 

 neither heard, or read any particulars respecting it. The native 

 goldsmiths here hold it in high esteem for making crucibles for melt- 

 ing gold and silver in, at a heat necessary for these purposes ; the 

 clay stands well, and does not change its colour, it contains a good 

 deal of mica, and a very small grained transparent sand. I am 

 not sure that it comes from Delhi, but it bears the name of that 

 place, and further inquiries shall be made about it. The specimen 

 No. 4, was also examined by Mr. Prinsep ; this he found to be less 

 refractory than No. 1, but still surpassing in that respect the Stour- 

 bridge clay, so that we have in India two clays for fire bricks, both 

 superior to that which is sent out from England, and of this fact no 

 one in Calcutta seemed to be aware. As late as the beginning of the 

 present year, within the last few months, Government purchased 

 and sent for the use of the Bullion Dep6t and Assay Office at Agra, 

 1200 fire bricks; better could have been obtained at Futtyghur. What 

 I have said I feel would be much more satisfactory, could I now give 

 any information respecting the cost of the fire bricks, and of the clay 

 from which they are made, but this at present I am not able to do. 

 Should the Government consider the subject deserving their serious 

 attention, and order me to examine the fire clays, which I have now 

 alluded to, I have much pleasure in being able to state, that I should 

 be assisted in my investigations by Mr. Pyle, who, as having been 

 connected with Mr. Jeffreys in all his experiments on the produc- 

 tions of this country, will be able to render me most valuable 

 service. 



Extract from a Report, by Mr. A. T. Christie, dated the 5th of 



September, 1832. 



Para. 4. A few miles to the north of Mangalore, and in connection 

 with the laterite, I discovered an extensive deposit of pure Porcelain 

 clay, very closely resembling that of Lemoges in France, of which 

 the beautiful Sevres-ware is formed. I need not point out the impor- 

 tance of this article. Being found close upon the Coast, it might be 

 easily shipped, and sent home as dead weight ; or with the assistance
