RAW -SILK. 



(L.) the Board to possess very decided advantages 

 Bo^?ofTrade "^^^ ^^^^^ others .* first, from the cheapness of 

 2/ Sept. 1832. their construction ; and secondly, as compared 

 with the quadruples, from the superior quality of 

 the silk produced, and the greater quantity of 

 reeled silk yielded by the same number of cocoons 

 of similar description. 



3. These certainly are very great advantages, 

 and in the opinion of the Vice-President in Coun- 

 cil fully bear out the recommendation of the 

 Board, that the pottery ghyes should be generally 

 introduced. 



4. The great gain from the substitution of these 

 ghyes for the old basins and stoves, will arise 

 from the saving of seventy per cent, of fuel. But 

 this saving is nearly the same as was secured by 

 the previous invention of Captain Somerville, 

 who first proposed so adapting the fire, as that 

 the flame and heated air should go round the 

 basin before escaping up the flue or chimney. 

 Mr. Shakespear, however, has greatly improved 

 on Captain Somerville's plan of fire-place ; first, 

 by getting rid of the iron door, which added con- 

 siderably to the expense of its erection ; secondly, 

 by an improved construction within, renewable 

 with less trouble and expense ; and lastly, by the 

 substitution of common pottery basins for the 

 copper ones of Captain Somerville, which were 

 very costly, and as appears from the result of 

 these experiments, are injurious to the colour and 



quality
