A variety of this soil is found in the black sand of the drift, in which one-fifth is coarse 
gravel, and the remainder a fine sand in which the alumina is still less than in the pre¬ 
ceding example. It contains 4-5 per cent of vegetable matter, but which, on cultivation, 
soon disappears. It is a poorer variety than the yellow sandy loam. 
Soil from the western slope of Petersburgh mountain. 
Uncultivated, and containing undecomposed slate.

The Sparry limerock traverses the base of this slope. The only fact worthy of notice about 
this soil, is the large percentage of lime which it yields. It is probably local, and its 
general character indicates poverty rather than fertility. In some parts of Petersburgh 
hollow, however, the soils are excellent.
