This is about the average yield of the cotton oil mills al- 

 though in many cases the production of oil approximates 40

 duce the amount of meal. In the past few years the oil mills 

 have been securing a higher extraction of oil, averaging about 

 40 gallons per ton of seed. Dry, clean, mature seed yields more
