POMOLOGICAL DISTRICTS. 11 



Oklahoma below 2,000 feet elevation; and Arkansas north of lati- 

 tude 35°, also south of it wherever the elevation exceeds 500 feet. 

 The Allegheny and the Ozark mountains and the valleys of the 

 Ohio, the Tennessee, and the Cumberland, and portions of the 

 Wabash, the Mississippi, and the Arkansas rivers are embraced within 

 this district. Portions of it are noted fruit regions, while throughout 

 its vast territory the hardier deciduous fruits flourish. Many of the 

 varieties recommended succeed best in certain localities within the dis- 

 trict. An exception to the general character of the district occurs in 

 those portions of Kentucky, Tennessee, Arkansas, and southeastern 

 Missouri lying near the Mississippi River, where varieties adapted to 

 culture in districts 5 and 7 generally succeed. 



District No. 5. — Eastern North Carolina, South Carolina, and Geor- 

 gia below 500 feet elevation; and Florida north of latitude 30° east of 

 the Chattahoochee River and above 100 feet elevation. This district 

 embraces the southern Atlantic seaboard, with its many frith-like 

 indentations and valleys. The climate is generally mild, and within 

 its borders many of the more tender deciduous fruits flourish. 



District No. 6. — Florida south of latitude 30°, the remaining por- 

 tions of the State with elevations below 100 feet, and those portions 

 of Alabama, Mississippi, Louisiana, Arkansas, and Texas lying below 

 the 100-foot contour line as it skirts the coast from Florida to the Rio 

 Grande. This is the southern peninsula and the Gulf Coast district. 

 The successful culture of citrus and other subtropical fruits and nuts 

 is restricted to the peninsula portion of Florida and to the Delta of 

 the Mississippi. Tropical species are only recommended for that por- 

 tion of Florida lying south of latitude 27°, and are indicated by the 

 letter s in connection with the starring. 



District No. 7. — Florida west of the Chattahoochee River and above 

 100 feet elevation; Alabama, Mississippi, Louisiana, and Arkansas 

 above 100 and below 500 feet elevation; and Texas south of Red 

 River and above 100 and below 1,000 feet elevation. This may be 

 denominated the valley district. It embraces portions of the Chat- 

 tahoochee, Alabama, Pearl, Mississippi, Arkansas, Red, Sabine, Colo- 

 rado, and Rio Grande valleys. The climate in the eastern and larger 

 portion is warm and moist, in the extreme west more dry and tending 

 toward aridity. A wide range of the more tender varieties and spe- 

 cies is adapted to culture in the district. 



District No. 8. — Illinois north of the 500-foot contour line as it 

 crosses the State between 38° and 39° latitude; a very small portion 

 of southwest Wisconsin; Iowa south of about latitude 42° 30^; the 

 Missouri River Valley portion of southeastern South Dakota; 

 Nebraska and Kansas below 2,000 feet elevation; and Missouri 

 north of a line drawn from near St. Louis and along the elevation
