NEW PROCESS FOR CLAYING SUGARS. 47 



Thus the labour of claying 416 feparate forms, with refpeft The new me- 

 to the time employed in doing it, is to that for the fame num- Jjjj^ Jf* 

 ber of forms contained in 16 cafes, as 206,844, to 11,360, or a t, out one t wen- 

 as 51,711 to 2,840. Now therefore, in order to clay the tieth P«t of the 

 quantity of 416 forms of fugar in my 16 cafes, (reckoning the 

 day's work of each man at nine hours) I employ only one day 

 and 2,360 hours, whereas the claying of 416 feparate forms 

 requires 22 days and 8,844 hours. ^ 



I find alfo another faving of time and labour when the earth 

 is to be removed and the bottom cleaned. This work, which 

 requires a day's work of four men for the 416 forms, is per- 

 formed in half a day by one man, upon the fame quantity of 

 fugar in the cafes. I have made this comparifon with my 

 watch in my hand. 



2. Ftzver Difficulties 



Though our cultivators are 

 in the habit of working the 

 forms and making their bot- 

 tom, it frequently happens that 

 they negled to remove the 

 fountain completely ; frequent- 

 ly alfo they do not uniformly 

 comprefs the grained fugar 

 which they had taken out of 

 the form, in order to feparate 

 this fountain, and which they 

 replace in it before making the 

 bottom. In that cafe, the fil- 

 tration of the water of the clay 

 does not take place uniformly, 

 but meets with obftacles to- 

 wards fome of its fides; and 

 the bottom, after this claying, 

 exhibits diftinfl marks of the 

 defective manipulation.
