barnyard mauure. Since the soil is heavy, being fine in texture and 

 rather compact, it requires strong teams and heavy machinery for 

 the most profitable handling of the type.

AVERAGE CHEMICAL ANALYSIS. 



GEORGEVILLE SLATE LOAM. 



The slate loam type covers about 13,000 acres and is developed 

 mainly in the northeastern part of the county. It represents the rough- 

 est surface features of any soil in the county, consisting of strongly 

 rolling to hilly areas bordering the larger streams. These slopes, how- 

 ever, have a comparatively smooth surface, and erosion is not very 

 active. 



This soil is distinguished from the silt loam on account of the large 

 quantity of slate and shale rock fragments, ranging from 1 to 6 inches 

 in diameter and being distributed over the surface and mixed with the 

 soil. Usually the bedrock or broken slate is reached within 3 feet of 

 the surface, and then outcrops in places. 



Owing to the prevailingly rough surface and the presence of the slate 

 fragments which interfere to a considerable extent with cultivation, 

 very little of the Georgeville slate loam is cultivated. Most of the 

 type is best suited to pasturage purposes and apple growing, and the 

 rougher areas to forestry.
