ing much of the material that formerly was allowed to accumulate about the factory 

 in fermenting heaps to the extent of sometimes becoming a nuisance to the neigh- 

 borhood. . 



At pea canneries several methods of utilizing the vines are in use. They may 

 be converted into silage, either by putting into silos or stacking in large stacks. 

 In some sections the vines arg cured for hay. They are also valuable as a fertilizer. 



Com husks and cobs are also used for silage. Experiments were made by the 

 -United States Department of Agriculture in regard to the feasibility of using the 

 refuse from, the <;?i,nning of corn|or the production of alcohol. It was found, that on 

 account of the 'expensive rhachinefy and apparatus required in the manufacture, 

 a small factciry could not profitably utilize the corn waste for alcohol. It was 

 shown that where several factories were located within a short radius of each other, 

 by shipping their waste to a central plant, it might be used up to advantage. 



Apple cores, "chops" and. peelings are usually either usedj^f or vinegar making, or 

 are made ii^ into apple jelly. From one factory visited by the writer, the apple 

 cores and peelings were dried, baled, and shipped to Europe, "to be made up into 

 champagne." ,, 



Peach pits are sometimes sold to nurserymen for seed. Sometimes the pits are 

 cracked and the meats used for almond meats. In many factories, no use is made 

 of the peach stones. 



In the classes of foods in which the waste is not large, the refuse is either hauled 

 away to a dumping ground near the factorjf, or is taken away by farmers for its 

 manurial value.
