them was $21 (per acre), while the value of two successive crops 

 of corn plus the value of a crop of cowpeas sown in the first crop 

 was $33.54 (per acre)." In the above test corn and peas were 

 valued at 50 cents per bushel and cowpea hay at $10 per ton, 

 which was the approximate local market value of these products 

 in 1899 and 1900. In 1901 and 1902, these tests were repeated 

 with additional plots from which the peas were gathered, but the 

 vines allowed to remain in the field and grazed by cattle when 

 the corn had been gathered. The local market value of cowpeas 

 and corn in 1901 and 1902 was $1 and 70 cents per bushel, and 

 cowpea hay $10 per ton. The severe drouth of 1901 lowered the 

 average yield of corn to about one-third of a full crop. The 

 yield of cowpeas, however, was the highest recorded at Fayette- 

 ville, and the cowpea hay yield was above the average for the 

 past five years. Notwithstanding the unusual deficiency of 

 moisture the presence of the growing cowpeas had no appreciable 

 effect to lower the yield of corn. The following table gives the 

 corn and pea yields and the value of the crops produced in two 

 years :
