GEORGIA, HOETICULTTJRE 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 

 eflfected 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 bo met with in a journey of a thousand 

 miles due liortb 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, andcoastforashort 

 distance inLand, are alluvial or quarternary, and here 

 the vegetation is of a subtropical character — ]}almet- 

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

 mock growth inland, together with the citrus, tig and 

 olive families, where cultivated. 



Sliglitly beyond the tide-w.ater limit begins the vast 

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

 grass Region," which extends inland some 100 miles, on 

 an average, covering nearly the whi>le of the tertiary for- 

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

 extending diagonally across the state, separates the ter- 



GEOEGIA 



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 nortliwest 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 ai-e tin- Ap])alacliian foothills and then the 



Pear and melon belt. 

 Fig and citrus belt. 



900. Georeia, to show horticultural reeions. 



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 ; 



Horticultural Areas : Currespondimj Geological Divisions.

2. Pear anu Melon Belt Tertiary Form,itioii 



3. Pbaoh anii (4RArE Belt Met:imorphic Formation 



4. Apple A.N'ii CUERRT Belt Tennessee Dip 



1. The Fill 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 sub.iect to iu.iury from 

 frost. It is the h(Oue of the Ogeechee lime, and formerly 

 l)oth indigo and the olive fl<.urisbed on the Sea Islands, 

 but their culture has been for nuiny years abandoned. 

 Figs grow to perfection. About the ports -especially 

 Savannah-heavy trucking is fidlowed for the northern 

 market — idiiefly potatoes, strawberries, cabbages, celery,
