PRACTICAL AGRICULTURE. 19 



Beans should follow a corn-crop. 



It is a frequent practice to mix a quantity of peas 

 with beans, generally in the proportion of about half a 

 bushel to the acre. 



The straw of the bean is nutritious and wholesome. 

 It is generally given to horses, and is reckoned little in- 

 ferior to hay. 



The most common disease of the bean is a species of 

 rust, produced by parasitic plants of mushroom family, 

 growing upon it in the same manner as rust or mill-dew 

 on wheat. 



The animals that attack and feed upon the juices of 

 the bean are certain aphides, the most common of which 

 is of a bluish-black color, and is called the collier. In 

 some seasons this creature is very destructive. It be- 

 gins at the top of the plant and continues multiplying 

 downwards. A remedy, which has been suggested and 

 practised, is to cut off the top of the plants as soon as 

 the aphides appear ; and this may be a palliative if 

 carefully performed. 



THE PEA. 



Of the cultivated Pea there seems to be but one spe- 

 cies, comprehending our various cultivated kinds, whe- 

 ther grown in the garden or the field, namely : 



Pisum sativum — Cultivated Pea. 



Early hoeing in the case of this plant should never 

 be neglected. 



BUCKWHEAT. 



Polygonum Fagopyrum — Common Buckwheat. 



The soils suited to it are the lighter kinds. 



The seeds of the buckwheat may be given advanta- 

 geously to horses, to poultry, and to hogs. Converted 

 into flour it makes most excellent cakes.
