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

 matology of Georgia is unitjue. Latitude and altitude 

 comlnne 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 uorth 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 SeaLslands, and coast for a short 

 distance Inland, are alluvial or quarternary, and here 

 the vegetation is of a subtropical character— palraet- 

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

 mock groNvth 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

mountains, in very irregular formation, their spurs ra- 

 diating in all directions. 



In exfrcTMp northwest Georgia the surface dips in a 

 general \v:iy toward the Tennessee river valley (eleva- 

 tion 700 feet I, 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, 

 erabr.acing 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 : 



Horticultural Areas : Corresponding Geological Divisions. 



1. Fig and Citrus Beut Quarternary Formation 



2. Pear AND Melon Belt Tertiary Formation 



3. Peach and Grape Belt Met,imorphic Formation 



4. Apple and Chekky Belt Tennessee Dip 



1. The Fig and Citrus Belt. — In this zone the citrus 



family does not thrive indigenously, nor is it planted for 

 commercial purposes. Yet oranges and lemons live and 

 bear unprotected, though latterly subject to injury from 

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

 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 — especially 

 Savannah — heavy trucking is followed for the northern 

 market— chieflypotatoes, strawberries, cabbages, celery, 

 tom.atoes, onions and peas.
