THE RIO GRANDE, N. J., SUGAR FACTORY. 



The sorghum-sugar factory at Eio Grande, near Cape May, N. J., 

 has been in operation three years. The company has a plantation of 

 about 3,000 acres. The soil is a sandy loam. 



This companj^ receives from the State of IS'ew Jersey a subvention 

 amounting to $1 per ton for the cane and 1 cent per pound for the 

 sugar. 



The cane is planted in hills so that it can be cultivated both ways. 

 Each hill is about 10 inches square, and the seeds are planted over this 

 surface and not all in one place. 



More seed is planted than necessary for a full stand. After the plants 

 are well up the weak and slender ones are removed, leaving about six 

 healthy stalks to each hill. 



The varieties of cane preferred by the company are early Amber and 

 early Orange, equal areas being planted with them. Other varieties are 

 grown for experimental purposes, but not in large quantities. 



The canes are brought to the mill on a tramway. The superintend- 

 ent told me that the cost of transportation was very much diminished 

 by it. 



Arriving at the mill the canes are lifted from the trams by machinery. 

 Double milling is employed. The bagasse from the first mill is sprinkled 

 with water before passing through the supplemental mill. 



The method of manufacture employed at Eio Grande is a modifica- 

 tion of the sulphur process. It is further set forth in the following 

 specification : 



To all whom if may concern: 



Be it known that I, Henry A. Hughes, of Camden, Camden County, New Jersey, 

 have invented a new and useful improvement in processes of defecating and clarify- 

 ing sacchtirine liquors, of which the following is a specification.
