pipe or cigar until after the building has been thoroughly aired. 

 It is usually best to fumigate seeds with carbon bisulfid in a 

 granary or shed removed some distance from other large 

 buildings, but with proper precautions the fumigating may be 

 done in any building. 



Summary. 



1. The cow-pea is a leguminous crop enabled by the bac- 

 teria that live upon its roots to make use of the nitrogen of the at- 

 mosphere and store it in the soil for the use of non-leguminous 

 crops like wheat and corn. 



2. Cow-peas make nutritious hay relished by nearly all 

 classes of stock, but the plant is a rank grower and the hay is 

 somewhat difficult to cure. 



3. Cow-peas planted with corn make ensilage of higher 

 feeding value than corn alone, being richer in protein. Cow-peas 

 planted with corn produce as much ensilage per acre as may be 

 produced by corn alone. 



4. Cow-peas planted with corn at the last cultivation in- 

 creased the yield of corn in which the cow-peas were planted by 

 more than three and one-half bushels per acre as an average 

 for five years. 



5. Cow-peas planted as a catch-crop between crops of 

 wheat in continuous wheat growing increased the yield of wheat 

 four and one-third bushels per acre as an average for five years. 

 Where cow-peas were used the yield of wheat has continually 

 increased. Where not used the yield of wheat has continually 

 decreased. 



6. Cow-peas used as a catch-crop after wheat in rotation of 

 wheat and corn increased the yield of corn over nine bushels 

 per acre as an average for four years. 



7. Cow-peas have proven a better crop than soy-beans. 

 They are more sure of making a stand, make a ranker growth 

 and larger yield of forage, and are better suited for planting 

 with corn for ensilage and for green manuring than soy-beans.
