effect of the claying. When, by examining the fugar in this 

 manner, we rind that there does not remain more than about 

 two inches difcoloured by the fyrup, it is the proper time for 

 claying it. ^Jf 



To prepare the fugar for receiving the clay, the very thin 

 cruft formed at its furface is firfl taken off, and is divided and 

 fpread out again upon this furface, which is pierced to the. 

 depth of fix lines with the edge of the trowel, which is after- 

 wards ufed for flattening and compreffing the bottom. After 

 this laft operation is performed, it is clayed in the ufuai 

 manner. 



The fat earth or clay which is generally ufed here for claying 

 of fugars, has in general the fault of retaining the water with 

 which it is diluted loo long, on which account it happens, 

 that whilft one part of this water filtrates into the fugar, an- 

 other, and that not the lead confiderable, evaporates into the 

 air. 



This earth has alfo another fault, which is very prejudicial 

 to the operation of the bleaching of the fugar; namely, that 

 of remaining for feveral days in part fufpended in the water, 

 before it is intirely precipitated from it, which renders this 

 fluid milky. Both thefe faults require to be corrected. 



After fome trials I fucceeded in doing this completely : my 

 procefs is fimple, eafy to be executed, and requires neither 

 expence nor lofs of time ; I can even affert, that the water 

 with which my earth thus prepared is diluted, depofits nothing 

 by filtrating into the fugar, but that it feparates as limpid as 

 the pureit rain water. I fend you fome fugar bleached by 

 this means.
