hut should then be transferred to the vacuum pan. Daring the 

 first part of the boiling in this pan the temperature should not 

 exceed 170° F., and when the syrup becomes denser a more com- 

 plete vacuum should be maintained so as to boil it about 140° F.; 

 in fact, the lower the temperature the better. 



The varieties of cane raised on the farm during the past season 

 were confined to the Early Amber, Early Orange and Honduras. 

 Of these the Early Amber is unquestionably the best for sugar 

 making, and our experiments were confined largely to this variety. 

 The total amount of juice in this cane is about 85 per cent, of 

 the total weight of the stalks, and the juice contained 9.20 per 

 cent, cane sugar and 3.4 per cent, glucose. This content of sugar 

 represents the average of not less than 200 pounds of stalks 

 stripped and topped, the greater part of which were lodged. 

 Moreover, the land on which this cane was grown was quite low, 

 and the soil a cold, clay loam, not well adapted for cane growing. 

 Taking these facts in connection with the bad season, it must be 

 looked upon as below the average yield. 



DEVELOPMENT. 



The development of the Early Amber cane raised on this farm 

 may to some extent be seen from the following analyses, which 

 have been made by me during the summer and fall :
