Oats are also cultivated throughout a wide range, but they are 

 better suited for countries possessing a lower annual temperature, 

 less sunshine, and a moister climate than those in which the cul- 

 tivation of wheat and barley is extensively followed. In Scotland, 

 the breadth under oats considerably exceeds that under wheat or 

 barley. Like wheat, the oat sends its root deep into the soil and 

 subsoil. It is cultivated in all, but more successfully on the 

 stronger class of soils. The analysis of this grain gives : — 



The Bean plant is grown with most profit on strong soils ; but 

 it is not cultivated to anything approaching the same extent as 

 the cereals last mentioned, as it enters but little into the compo- 

 sition of our bread stuffs. It is chiefly used for stock-feeding 

 purposes, and from the large proportion of albuminous compounds 

 which it contains, it is especially valuable in the maintenance of 

 muscle in hard working animals. This also applies to the other 

 cultivated leguminous plants — peas, tares, and clover. The fol-
