tions of sugar, not too concentrated. It is entirely unfermentable, 

 and will not become mouldy or undergo decomposition, if kept 

 for an indefinite length of time. It is therefore an excellent ma- 

 terial for shipping and storing. Sucrate of lime may be manu- 

 factured on the farm with a comparatively small outlay. The 

 juice is defecated as usual, and boiled down to from 30''-32'' B, 

 The syrup is then cooled and transferred to the sucration vessel. 

 This vessel is usually made of galvanized sheet iron. In the 

 center is a vertical shaft, carrying paddles. A certain quantity 

 of pure and finely pulverized lime is then ndded, which becomes 

 thoroughly mixed with the syrup by the motion of the paddles. 

 The lime and sugar quickly combine, forming the sucrate of lime, 

 which, when washed with cold water and dried, is ready for ship- 

 ment to the refinery, where the sugar is separated from the lime 

 and refined. This is, very briefly told, the process which we 

 believe can be successfully applied to the manufacture of sugar 

 from the sorghum cane. We trust that by another year, if these 

 experiments are allowed to CDntinue, some practical results in 

 connection with this and the diffusion process may be brought out. 

 It would have been very desirable to have made some experi- 

 ments with these processes during the past season, but our time 

 was entirely taken up by the work which has been done. More- 

 over, the limited amount of means at hand would not warrant the 

 construction of the special machinery necessary for conducting 

 these processes. 



PRODUCTION OF SULPHUROUS ACID. 



Considerable quantities of sulphurous acid are needed in mak- 

 ing syrup, and much expense may be saved by making it at the 

 factory. When sulphur is burnt in the air, each part of sulphur 

 unites with two parts of oxygen from the atmosphere, forming a 

 gas called sulphur dioxide. This gas is readily soluble in water. 



When water has a tempsrature of 50" F. it will absorb 50 vol- 

 umes, or one gallon of water will absorb 50 gallons of the gas. 

 As the temperature of the water rises, it becomes less capable of 

 absorbing the gas, so that at 70° F. it will absorb only 3i volumes. 

 The solution of this gas in water constitutes sulphurous acid*
