RECORD OF THE ANALYSES MADE AT RIO GRANDE DURING 



THE SEASON OF 1888. 



By Dr. ARTHUR T. NEALE/" 



In addition to studying the construction, the arrraugement, and the 

 management of the machinery, the chemist of this station attempted 

 to determine, at least once each day, the percentage of sugar in the sor- 

 ghum, as well as the percentage of sugar in the products from each 

 piece of apparatus used in this house. Breaks occur in this record 

 whenever it w r as necessary for him either to return for a day to New 

 Brunswick or to devote his entire attention to some one point of special 

 interest. 



The house was not open for work until the 2Gth of September, and 

 a few of the samples of cane analyzed about the 20th of that month 

 were taken from the crop standing in the fields. Such samples were 

 stripped and topped by hand. All of the other samples were drawn 

 from cane which was cleaned by machinery. They represent in each 

 case, approximately, 1,000 pounds of well-mixed shreds. 



The varieties of sorghum planted were: Early Amber on field No. 1; 

 Late Orange on that portion of field No. 12 which was worked after 

 the 23d of October; White African on a portion of field No. 2 har- 

 vested on the 27th instant, and Kansas Orange in all other cases. 



The exhausted chips were sampled as fast as they were removed from 

 the battery ; a roughly measured quantity being taken in each case 

 from each one of ten baskets. These portions were subsequently mixed, 

 subsampled, and milled in the usual manner. 



With a few exceptions, the samples of diffusion juice were, in all 

 cases, drawn from a tank holding 300 gallons. The samples of the 

 evaporator product were also drawn-from a similar tank. The record 

 in detail is shown on the following page. 



The averages drawn in this table prove that the cane crop in 1888, 

 relative to that of 1887, was poorer in sugar by 0.75 per cent, and lower
