thrive in cool, moist, tempenite regions. Like otlior legumes, 

 they draw much from tlio air and subsoil, and are most excellent 

 crops to alternate with wheat and the true forage grasses. They 

 like moist loamy soil, but this should not l)e in tlie highest con- 

 dition, else the plants "run too much to vines,"' at the expense 

 of a good crop of seeds. 



From It} to 4 bushels of seed to tlie acre is sown broadcast or 

 in drills, yielding 15 to 25 bushels of seed, wliich is a very nu- 

 tritious food for swine and sheep. 



The greatest enemies to this crop are the pea weevil or " bug*' 

 and mildew. 



Of "bitggy " jjeas only about one-fourth per cent will usually 

 grow, and these produce feeble plants. Seed can be obtained 

 from the North, where the bugs are not troublesome, and the 

 young crop can be fed out bugs and all. 



The weevil can be killed when young, by putting the peas as 

 soon as thi-eshed in a tight box with some bisulphide of carbon. 

 There is some difference in varieties, but hot, dry weather is quite 

 sure to favor the development of mildew, which weakens and 

 often prevents the growth of the plants or the production of a 

 good crop of seeds. In favorable localities enough attention is 

 not paid to this crop, both for feeding and to precede a crop of 

 wheat.
