RAW-SILK.

the chassum of the quadruple ghyes I observed 



many ffood threads, which I have no doubt the „ ^f^ZJ'',

same spinners, had each been at a separate basin, 29 Junei832. 

 would have wound off into good silk. 



The expenditure of wood for the experiment was 

 twelve seers eight chittacks each man, but ten or 

 eleven seers per diem would probably be sufficient 

 for the same purpose. Though I am of opinion 

 that, in this respect also, the pottery ghye, by 

 reason of the admirable construction of its fire- 

 place, which causes the smoke to circulate round 

 and round the basin before it escapes through the 

 chimney, would have the advantage of a smaller 

 expenditure. 



As to the quality of the silk in the instance of 

 this experiment, that spun at the pottery ghye 

 appears to be superior to the other. The colour 

 is better. All the copper basins, unless very 

 effectually tinned over, which those of the quad- 

 ruple were not, must discolour the water, and 

 of consequence the silk. It is likewise less flat 

 and knibly, which I can attribute only to the 

 threads passing round over the reel, instead of 

 under, as in the quadruple ghye ; for I observed 

 that the number of twists of the two threads were 

 the same in both. In consistency of thread the 

 produce of both seems equal ; and, in this respect, 

 superior to what was spun at Captain Somerville's, 

 the construction of whose reel appears to be some- 

 what opposed to this quality. I may remark,
