humid, while the less-connected western part is partly arid and partly humid 

 It is an important area to keep in mind, because it marks the transition from 

 cold to warm temperate conditions. 



Here many northern plants and animals find their most southern extension 

 of range, and many southern plants and animals their most northern exten- 

 sion. There are not so many forms which are peculiar to this great belt as in 

 the other areas we are studying; still there are three faunal divisions of it, 

 which may be kept in mind, that will help us to understand better the con- 

 ditions of its climate and physiography. These divisions are: (i) the eastern 

 Alleghanian; (2) the western arid; (3) the Pacific coast humid. 



Agriculture flourishes in the Alleghanian zone, but it varies in character 

 somewhat throughout these three faunal subdivisions. 



Let us follow out a table of the cereals, fruits and crops which characterize 

 these areas, and by comparing them learn something about the difference 

 in the fertility of the soil, due to varying climate and other conditions. The 

 following table, although subject to change and probably not complete, indi- 

 cates more clearly than a lengthy description the marked limitations or great 

 possibilities of each area :
