The samples of mill juice were taken during the fifth week, with the 

 water of maceration added. After that time this water was turned off 

 when the sample was being taken, so as to obtain the normal juice of 

 the cane as nearly as possible. Owing to the difficulty of obtaining ac- 

 curate samples from a continuous stream of juice, however, these sam- 

 ples of mill juice can not properly be compared with later products, 

 and are of value simply as showing the quality of cane going into the 

 house. I began control work with the sulphured juice, taking this as a 

 starting point, as accurate samples of it could be obtained, which prop- 

 erly represented the juice as it entered the house. For an exact com- 

 parison of the sulphured and clarified juices, the corresponding samples 

 of each, in parallel lines, should be taken, and if this is done it will be 

 seen that little or no increase in the purity was attained by the proc- 

 ess of clarification contrary to the usual experience, the removal of 

 solids in the scums usually raising the coefficient of purity one or two 

 points.
