yields, under the conditions of these experiments, 275 

 pounds of oil less per ton of unhulled nuts than the 

 average of the two Spanish varieties. 



The oil in the peanut hulls is not included in the 

 above table. U. S. Department of Agriculture Farmers' 

 Bulletin No. 751, page 9, shows that the oil in the pea- 

 nut hulls of different varieties varies from .73 percent 

 in the Virginia Runner, to 3.53 percent in the Virginia 

 Bunch. The analyses of hulls * at Auburn shows 1.2 

 percent oil, 5.38 percent protein, 3.97 percent ash, 65.6 

 percent crude fiber, and 15.6 percent carbohydrates. 



Based on the average percent of oil and of sound 

 peas in the above table, the varieties of unshelled pea- 

 nuts take the following rank in pounds of oil per ton: 



White Spanish _702 



Red Spanish 693 



Valencia 572 



McGovern 548 



Tennessee Red 527 



North Carolina Runner 524 



Virginia Runner 493 



Jumbo 354 



Oil Production and Yield as Reported by the Oil Mills. 



From a questionnaire that was sent to a number of 

 Alabama oil mills known to be crushing peanuts, the 

 following facts were learned. These manufacturers are 

 using the Anderson Expcller type of mill, which has a 

 capacity ranging from 400 to 600 gallons of oil per day 

 of 24 hours. The operators of these mills report that 

 this machinery extracts from 92 to 95 percent of the oil 

 contained in the peanuts. 



They report from a ton of peanuts of the Spanish 

 varieties, from 600 to 700 pounds of oil and from 1200 

 to 1300 pounds of peanut cake or meal. A ready sale 

 for all peanut products is reported by the mills. 



Some mills report that the color of the shelled peas 

 is a matter of no importance. Others express a pre- 

 ference for "white" peanuts. All mills except the one 

 at Brundidge prefer the White Spanish variety. The 

 Brundidge mill ])refers the North Carolina Runner, 

 stating that its yield is higher than the yield of Spanish. 

 The yield of peanuts in the locality of the mills in 1916 

 was estimated by the mills at 850 pounds of nuts per

 ment Station.
