t-ion. In order to promote fermentation, guano is sometimes thrown 

 into the vat with the mostos. When properly fermented, the mostos 

 is drawn off to the still, sometimes of the coffey type. After distilla- 

 tion, the exhausted mostos passes into the drainage ditch. The alco- 

 hol is run to vats in the alcohol room. The 30 degree distillate ia 

 called rum and is kept separate. The alcohol is put up in tin con- 

 tainers of six gallons capacity, boxed and sealed. The revenue on al- 

 cohol is considerable and is based on the per cent of pure alcohol in 

 the commercial product. 



Sugar house work in Peru has not yet been so systematized as to 

 make it possible to secure full and accurate data concerning it. But 

 from notes gathered from several particular factories, a few are 

 selected to supplement the general description. 



While some of the data may be more or less approximate, it is 

 sufficiently illustrative. The canes worked upon by these factories 

 contain about 14.25 to 15. 75^ sugar. The juices occasionally contain 

 as low as 15.5 and as high as 21.5 % sucrose; but generally, they do 

 not vary much, the usual juice containing 17 to 18 % sucrose.
