GEORGIA, HORTICULTURE 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 

 Tennessee line) stand a little more than 5,000 feet high. 

 Intermediately may be found as varied a climate, and 

 consequently as extended a range of horticultural pro- 

 duction, as can be met with in a journey of a thousand 

 miles due i^orth and south, in a region of normal eleva- 

 tion, such as the Mississippi valley. 



Measurably the geology of the state corresponds with 

 its elevation and consequent climatology, and is not com- 

 plex except in the extreme northwestern portion. Two 

 formations the tertiary and metamorphic cover nine- 

 tenths of its area. The Sea Islands, and coast for a short 

 distance inland, are alluvial or quarternary, and here 

 the vegetation is of a subtropical character palmet- 

 toes and live-oaks on the islands and pines and ham- 

 mock growth inland, together with the citrus, fig and 

 olive families, where cultivated. 



Slightly beyond the tide-water limit begins the vast 

 sweep of the pine forests, known locally as the "Wire- 

 grass Region," which extends inland some 160 miles, on 

 an average, covering nearly the whole of the tertiary for- 

 mation. A range of low sand hills, about 300 feet high, 

 extending diagonally across the state, separates the ter- 



tiary and metamorphic regions. At its base the land has 

 attained an average altitude of less than 200 feet. 



From the summit of this ridge or terrace, formerly the 

 primordial sea-beach, stretches the metamorphic region 

 the red clay or cotton belt rising gradually toward 

 the northwest until the Piedmont escarpment is reached 

 another low hill range on the southern side of and 

 parallel to the Chattahoochee river valley. The height 

 of this escarpment varies from 1,000 to 1,500 feet. Be- 

 yond this are the Appalachian foothills and then the

In extreme northwest Georgia the surface dips in 

 general way toward the Tennessee river valley (elevi

 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-

 embracing nearly all of the North American species, 

 oak and hickory predominating. 



All this has been a necessary preface to a division oJ 

 the state into separate horticultural areas, which coi 

 respond in the main with its geological features, an 

 may be classified as follows :

1. The Fig and Citrus Belt. In this zone the citi 

 family does not thrive indigenously, nor is it planted fc 

 commercial purposes. Yet oranges and lemons live an< 

 bear unprotected, though latterly subject to injury fron 

 frost. It is the home of the Ogeechee lime, and formerlj 

 both indigo and the olive flourished on the Sea Islands, 

 but their culture has been for many years abandoned. 

 Figs grow to perfection. About the ports especiall] 

 Savannah heavy trucking is followed for the northeri 

 market chiefly potatoes, strawberries, cabbages, celery, 

 tomatoes, onions and peas.
