In America the consumption of earth nuts is enor- 

 mous, and the crop which, prior to 1860, was very 

 insignificant, had reached, in 1871, the value of 

 2,250,000 dollars. The market price varies with the 

 quality from $2 to $2.50 per bushel, and the weight of 

 a bushel is from twenty-four pounds, yielding one 

 quart of oil to the bushel, to thirty-four pounds, yield- 

 ing five quarts of oil. The crop averages forty bushels 

 per acre. A machine has been invented by Thos. L. 

 Colville, of Wilmington, North Carolina, for hulling 

 and winnowing them. The demand is so great that 

 pea nut shops have them roasting all day to supply the 

 retail trade, and the sales of one man amount to up- 

 wards of one thousand bushels a year. The nuts 

 thrive best near the sea, and require lime in the soil.
