ness. In this form it ia salable to the refinery as well as to, 

 consumers. At an outlay of $3,000 a farmer, or a combi- 

 nation of farmers, can sell sugar to the refinery, or to the 

 general market, that is equal to the best coffee sugars. 

 This is done by the addition of a "centrifugal," an iron box 

 with gauze wire sides, that revolves with amazing rapidity, 

 in a hollow cylinder, and it throws out every particle of 

 fluid matter, retaining only the solid crystals of sugar. Of 

 course, the centrifugal can only be revolved with the aid of 

 Steam. But steam is so far superior to furnaces for the 

 evaporation of the juice of sorghum that it will be an im- 

 provement to employ it for that purpose even if a centrifu- 

 gal is not provided. Hon. Seth H. Kinney, of Morristown, 

 Minnesota, proposes to sell these machines and send a man 

 to teach their use. 



Another method of selling to the refinery is the " mush 

 sugar." This is made by the use of the ordinary mill and 

 evaporator and granulating pans. First boil the juice to a 

 certain consistency, shown by an instrument called the 

 saccharometer, then place the syrup in pans provided for 

 the purpose, that shut up like a chest of drawers. It here 

 remains for a certain time, varying from forty-eight hours 

 to three weeks, when it is found to be in the condition that 

 is called mush sugar, and it is then ready for the centrifugal 

 or the refinery. It would be a good idea for several neigh- 

 bors to pool together and provide one centrifugal for a 

 hundred mills, as it can be run at any time throughout the 

 winter or the succeeding year. 



These machines will soon appear, however, when the erec- 

 tion of a refinery creates a demand for their services. 



Messrs. Stockell and Scales have kindly placed at the dls- 

 ppsal of the Department of Agriculture a corre-^pondenee 

 held with persons owning these supplemental machines, (rom 

 which the following information has been gathered. The 

 reader will notice how retic^nt they are about giving the
