The Dawn of a New Constructive Era 75 



That means 100,000 acres of coastal plain. Some of Lee County 



is in the coastal plain and some in the mountains to the north, so 



that the bar for this county does not represent all the unimproved 



land. The yellow color represents sand, the blue color, wet and 



heavy lands, the uncolored, the sandy loam, and the red color, the 



rough and mountainous lands. The wet and heavy lands include 



all lands wet, or frequently overflowed and all soils heavier than 



loams. 



It is well known that sand has a certain adaptability to crops — 



that is — there are certain crops which you can grow on sand, and 



certain others which do not do well on such soil. There are certain 



other crops adapted to wet and heavy lands — lands that have an 



abundance of moisture : and certain other crops are adapted to _ , ,

sandy loams. 1 will venture to say that the wet and heavy lands y^et Lands- 



of the South are probably the lands on which stock raising will de- What They 

 velop in the future the best, because they are the lands on which Are Adapted 

 forage crops and grasses will grow the best. The sandy loam ^°''- 

 lands are lands wide in their range of adaptibility. They are well 

 adapted to the growth of truck crops and cotton. Truck crops and 

 cotton, then, are probably the best crops for the sands, forage crops 

 for the wet and heavy lands, forestry for the rough lands, and gen- 

 eral farm crops for the sandy loams. 



It is not necessary to take up in detail each of the individual 

 counties, but I will call your attention to certain general character- 

 istics of the several states. 



You will notice a considerable amount of yellow in the bars 

 for the Alabama counties, showing the presence of a considerable 

 amount of sand in Alabama. You will note also that the blue color 

 representing the proportion of wet and heavy land is not extremely 

 prominent. It is, however, in Clark County and Washington Coun- 

 ty. Practically all of this land in Washington County is wet land 

 and not heavy. There is a large amount of sand in Baldwin 

 County. As you go north, the sandy loam makes up a larger pro- 

 portion of the soils. In the northern part of the state the clays rep- 

 resent a considerable proportion of the land, but it happens that all 

 the clays are under cultivation and do not enter into this calculation. 



Next I will take Mississippi. Another factor enters there, and 

 that is lack of knowledge. We know much less about the soils of 

 Mississippi than of Alabama, because only a relatively small part of 

 the state has been covered by soil surveys up to the present time.
