In 1886 the New Jersey station continued its analyses at Kio Grande.

COMPARISON OF MILL AND DIFFUSION JUICES FOR 1886. 



At Kio Grande the chemist of the New Jersey station made analyses 

 for the purpose of comparing mill and diffusion juices. 2 

 The means are as follows : 



A mean of eight experiments made by J. F. Willcox, of New York, 3 

 in 1886 shows 9 per cent, sucrose in sorghum juice. 



ANALYTICAL DATA FROM THE EXPERIMENTS AT THE NEW JERSEY 

 AGRICULTURAL STATION. 



The systematic investigations made by Dr. Geo. H. Cook, director of 

 the New Jersey Agricultural Experiment Station, have already been 

 quoted in the data given. These experiments were commenced in 1881 

 and have been continued every year since. The chemical work has been 

 in charge of Dr. A. T. Neale. The results of these experiments have 

 been so interesting and instructive that I have grouped them together. 



In 1881 fourteen varieties were planted, of which only five matured. 4 

 The sucrose in the juice of these five matured varieties was as follows : 

 Per cent, 8.58, 7.28, 6.50, 7.60, 14.06. Mean, 8.80 per cent. 



The same season 5 sixteen plots of Early Amber were treated with 

 various fertilizers, and the yield of sugar calculated per acre. 



The percentages of sucrose in the juice of the several plots were as 

 follows: 9.70,0.43,9,9.27, 9.68, 9.94,10.51,11.65, 11.43,9.84,9.57, 11.61, 

 9.73,9.44,12.01. Mean, 10.16. 



In respect of the experiments Dr. Cook makes the following report : 6 



After a struggle, which has now lasted more than twenty-five years, sorglmin to- 

 day does not occupy its true position among sugar-producing plants. Its advocate- 

 justly claim that this is due to our lack of information, not only in regard to the mauus 

 facture of sugar from it, but also in respect to its proper cultivation. For some time 

 past authorities have felt that the hope of having a small sugar-house on each farm 

 must be abandoned, and that our attention must be turned towards the more rational
