INVESTIGATIONS AT THE COLLEGE 47 



suitable land properly fertilized. The juice from the 

 beets contained some 14 per cent, cane sugar, and the 

 beets were equal to the best thus far produced at the 

 College. 



In Experiment II, 100 pounds of beet seed were 

 imported from Saxony. Four acres of beets were 

 planted from this seed on the College farm. Ten pounds 

 of the same seed were sent to the New York Agricul- 

 tural Society and planted by six farmers in different 

 parts of the state. Samples of the beets grown were 

 sent to Goessmann, who found the juice to contain all 

 the way from 7.37 to 15.10 per cent, of sugar. The 

 wide variations he believed to be due to the method 

 of fertilization. Highly nitrogenous manure, or the 

 application of partly decomposed stable-manure in 

 the spring, was considered particularly objectionable, 

 causing an increase in the amount of impurity in 

 the juice and preventing a favourable development of 

 the sugar. He stated that a satisfactory juice should 

 not contain over one part of impurity to five parts 

 of sugar. He laid particular stress upon planting the 

 beets in deep mellow loams that had not been too 

 heavily manured. The application of well-rotted stable 

 manure in the spring, or preferably the year previous 

 to planting the beets, was advised, and supplementing 

 the same with sulphate of potash and superphosphate. 



Experiment HI was conducted on the College farm. 

 He found fresh horse-manure to be quite unfavourable 

 to the development of cane sugar. Land that had re- 

 ceived stable manure two years previously, and that 

 receiving sulphate of potash, produced beets containing
