1706, 707] ANALYSIS OF PINE UPLAND SOIL. 351 



produces about 705 lbs. of seed-cotton per acre, and lasts pretty well. This 

 region is remarkable for the frequent occurrence, both in uplands and bottoms, 

 of white, "crawhshy " tracts; characterized as usual by a Huckleberry and 

 Post Oak growth in the uplands, where it is very poor, the cotton running to 

 weed without boiling. The white bottom soil, however, characterized by an 

 admixture with the usual bottom growth of the region, of Bottom Pine and 

 Water Oak, and the absence of the Magnolia, produces a small, but well boiled 

 cotton stalk, but is entirely unsuited to corn, as is equally the case in the 

 uplands. This land, of which considerable bodies are said to occur lower down 

 the stream, certainly requires drainage in the first instance, and vegetable matter 

 in the second ; what may be its other necessities, analysis will probably show 

 (^660, ffi). The prevalent, chocolate-colored bottom soil of the Amite closely 

 resembles that of the Homochitto (1T711, If.) and is very productive. 



766. Thence eastward to Summit, and from Summit towards Holmesville, 

 the " Pine Hills " character becomes more and more predominant ; the Hickory, 

 the Short-leaf Pine, the Spanish {"Bed ") Oak become less frequent, and the 

 country more hilly. At Summit, where a good deal of stout Post Oak, with 

 occasionally a Spanish (" Bed ") and (true) Red Oak, still mingles with the Pine, 

 the ashy surface soil is 7 to 9 inches deep, and beneath it lies a good (so far as 

 its physical properties are concerned — TT510, fF.) yellow loam subsoil, several 

 feet in thickness, resting on a sandy hardpan. 



Analyses of the soil and subsoil of the pine uplands, taken at Summit, gave 

 the following result :
