dreg yield 3 Ib. of dry food. One gallon of thin dreg, on eva- 

 poration, leaves 4235 grains of solid matter, while 1 gallon of 

 thick dreg leaves 10,884 grains of solid matter. Of the 4235 

 grains left in the first case, 3871 are organic matter, and 364 

 inorganic matter. Of the 10,884 grains in the second case, 

 10,290 are organic matter, and 594 grains are inorganic 

 matter. 



Dreg is given by dairymen living near distilleries in large
