OOITON-SEED MEAL. 



This is manufactured from the seed of the cotton-plant. The seed 

 is tufted by a thick coat of lint, which is exposed, as the plant ripens, 

 by the opening of the boll or pod. The lint which forms the cotton 

 of commerce is removed from the seed by the operation of ginning, 

 although a considerable quantity of short lint e^till clings to the seed 

 coat. The proportion of seed in upland cotton* is about 2 to 2.2 

 pounds for each pound of lint, in sea-island cotton f 2 to 2.5 pounds. 

 The supply of this material is therefore very abui.daut. The fuzzy 

 seed from the ginning process is then subjected to a rough milling 

 process for the removal of the black hull from the oval seed. The 

 hull ie further worked to secure the small amount of lintel adhering. 

 The decorticated seed — that is, that from which the hull has been 

 removed — is then cooked, placed in jute sacks and subjected to heavy 

 pressure in powerful hydraulic presses, whereby a portion of the 

 oil is expressed. The press cakes, the "cotton-seed cake" of com- 

 merce, are afterward fine ground, yielding the cotton-»eed meal. 

 The average theoretical yield, as compared with the average milling 

 product, IS as follows :J
