76 The Dawn of a New Constructive Era 



A solid colored bar represents a surveyed county, while a bar col- 

 ored only in skeleton form represents an unsurveyed county where 

 the proportions of the various kinds of lands given ai-e based upon 

 the character of the land in the nearest surveyed county, or upon 

 the general knowledge we have acquired in our work in the state. 

 We have gained more or less general knowledge of the character of 

 soils in all parts of the United States, and that factor enters into 

 this estimate. 



Without going over the counties in detail, I will call your at- 

 tention to the absence of yellow — the nearly complete absence — in 

 the soils of Mississippi. In these counties lying in the southeastern 

 and eastern part of the state there is some sand. In the western 

 part of the state, not including the delta, the blue color, you will 

 notice, is very prominent. 



In other words, Mississippi is a state of rather heavy soils; 

 that color represents both wet and heavy, but in Mississippi it rep- 

 resents relatively heavy land, with very little wet land. It is prac- 

 tically all silt loam. Mississippi is, therefore, a state of silt loams, 

 Mississippi's well drained, as it happens in this case; a state, therefore, where 

 Soils Largely the lands are adapted to forage crops. You will notice also that 

 Silt Loams the percentage of sandy loam is rather lower than in the case of 

 Alabama, but not so high as in Louisiana, for example. You will 

 notice also that the red is more prominent in Mississippi than in 

 Alabama. There are more rough lands in Mississippi than in Ala- 

 bama, but a great deal of this rough land shown here represents 

 silt land also. It represents land that can be converted into pasture. 

 You will notice again that Louisiana is not covered solid. We 

 know relatively little about the details of Louisiana soils, except in 

 a few places. We have surveyed Tangipahoa Parish in the east, 

 Winn Parish in the northwest, Iberia in the southeast, East Baton 

 Rouge, East Feliciana and Bienville, and recently surveyed Rapides, 

 but the data for the latter is not yet available. You will notice that 

 Louisiana the percentage of sand is low. The percentage of wet and heavy 



Rich in Sandy land is rather high. The percentage of rough land is also pretty 

 Loams Jq^ -j-jje ^jug color is especially prominent in counties east of the 



Mississippi — Tangipahoa, East and West Feliciana. You will notice 

 also the percentage of sandy loams — which is a widely adaptable 

 soil — is relatively high. That, like the others, is based on estimate, 

 of course, but the estimate is based on the general knowledge we 

 have — a good deal of general knowledge and the results obtclined by 

 the surveys in the nearest surveyed counties.
