GEORGIA, HOKTICULTUKE IN. Fig. 900. The cli- 

 matology of Georgia is unique. Latitude and altitude 

 combine to exaggerate the four and one-half degrees 

 covered by the state from south to north into at least 

 ten, thereby embracing an extraordinary range of cli- 

 mate. In something less than 300 miles a transition is 

 effected from a subtropical to an almost boreal vege- 

 tation. 



Proceeding northwestwardly from the coast, the coun- 

 try rises gradually until it culminates in the Blue Ridge, 

 the highest peaks of which (in Towns county, on the 

 Tenness. .. lin.) stand a little more than 5,000 feet high.

mountains, in very irregular formation, their spurs ra- 

 diating in all directions. 



In extreme northwest Georgia the surface dips in a 

 general way toward the Tennessee river valley ( eleva- 

 tion 700 feet), interspersed, however, with a chaos of 

 mountains and coves, with a complex tangle of geologi- 

 cal formations, from lower silurian to eocene. 



The prevailing natural growth of the tertiary is yel- 

 low pine — that of the metamorphic region hard woods, 

 embracing nearly all of the North American species, 

 oak and hickory predominating. 



All this has been a necessary preface to a division of 

 the state into separate horticultural areas, which cor- 

 respond in the main with its geological features, and 

 may be classified as follows :
