EXPERDIEXTS IX SUGAR MAXUFACTURE, ETC. 515 



weigbed, the juice measured in the defecator, of which the capacity 

 ■was known, and at intervals during the day samples of the freshly ex- 

 pressed juices were taken for analysis in the laboratory. The syrups 

 produced were also carefully weighed and also analyzed. 



As evidence of the condition of the crop, it may be mentioned that 

 all the seed which had sufficiently matured to make it possible to save, 

 was carefully gathered, and the total product of the 9o^ acres was 

 about 150 bushels, or one and two-thirds bushels per acre. If we es- 

 timate 17 bushels of seed to the acre as a reasonable crop for land of 

 the character of that selected for growing this sorghum, it will be seen 

 that only 10 per cent of the ci-op had reached maturity. As this, un. 

 fortunately, was iuterraixed with the other nine-tenths in everv condi- 

 tion of immaturity, a large portion not even in blossom, the resultine 

 syi'ups produced may be anticipated. 



On this point, the statements of Peter Lynch, the sugar-boiler, are 

 conclusive, there being, as he says, but two days, October 4th and 5th, 

 when he received cane in even a reasonably matured state, and from 

 this he readily produced sugar. The report of Assistant Parsons, who 

 had immediate charge of the chemical and other work in the mill, 

 will be read with interest as a conclusiye statement of the several 

 causes of failure made by an expert of amj^le experience. See tables 

 A, B, C. 



Since this matter is of such vital practical importance, in connection 

 with the production of sugar from sorghum, a brief review of some of 

 the salient points clearly established will be appropriate. 



Besults from Analyses of Thirty-five Varieties of Sorghum grown in 1881. 

 By reference to the table, page 198, giving the general results from 

 analyses of thirty-five varieties of sorghum in 1881, it will be seen that 

 the available sugar in their juices during the successive stages was as 

 follows :
