meet any difficulty arising in the grinding with prompt 

 redress. 



I may mention here that a hardly less formidable 

 enemy to diffusion had to be overcome by the beet sugar 

 industry in the shape of the fodder question. Before 

 the introdu6iion of diffusion, 1865, the press refuse 

 sufficed in a building of the size of Nonpareil to fatten 

 two to three hundred oxen, which previously had done 

 good service in the field and building yard, while the 

 chips represented a poor and unwholesome fodder, which 

 could only be used with the addition of artificial strong 

 food ; only a few years ago they succeeded in making 

 the exhausted chips once more a valuable food, long 

 after diffusion had triumphed all over Europe, as it has 

 done since 1875. 



Among the different modes of arranging the diffusion 

 cells, the circular one is undoubtedly preferable to the 

 one with single or double rows, as with the former mode 

 a better way of removing the exhausted slices has been 

 found in the turn table invented by Mr. L. JONES. From 

 the turn table the exhausted chips should reach the mill 

 by the shortest way possible, as it is difficult with the 

 wet chips to make any kind of carrier answer. 



With regard to the number of cells in the diffusion 

 battery, I consider 14 most suitable, each of them holding 

 about 20 cwt. or one ton, and the diameter being i to 3 to 

 the height. Changing the cells as quickly as possible is 

 conducive to the obtaining of a juice with a high quotient 

 of purity and consequently to obtain a purer massecuite 

 which leads to a higher curing. The maximum duration 

 of one hour from the moment a cell is put under pressure 

 until the time it is emptied of the exhausted chips should
