Tlic observation made with respccL to the size of tlia 

 trees in the hilly region, is more applicable to tlie moun- 

 tainous regoii ; because the soil is still closer, and the 

 rocks lie still shallower: In some of the vailies however, 

 where the mould and vegetable substances from the 

 mountain steeps, have been obstructed and gathered 

 many feet in depth, trees oi enormous size are found^ 

 The trees which prevail ni this region, are those which 

 delight in a high, dry, firm sail. These viirv in their 

 kind and species according to the fertility of the soil in 

 this region. The growth of the mountain steeps is ve- 

 ry different from that of the dry vailies. On the steep 

 sides of the mountains and purchcd summits, stunted 

 oaks and meagre starveling pine is the prevailing 

 growth. In the vailies you find all kinds of oily nut trees, 

 of hard wood, viz. hickory, shell bark hickory, white 

 wailnut, haz;?ie nuts, also ash, beach, wild cherr}-, ma- 

 ple, po};lar and locust, which last prevail most in calcai- 

 rcous vailies. 



My opportunities v/ill not allqw me to assign to each 

 kind pf tree mentioned, the part of this region in which 

 it most delights. This much is ascertained, that thej^ 

 prevail more in the mountainous region than in the 

 other regions already clescrihed. 



"X'S^ith these ^^^w generalizing observations upon the 

 classification of soils, and with this imperfect description 

 of the regions we have enumo'ated and attempted to 

 bound, I shall leave that part of the subject, and go 

 on, in my subsequent niunbcrs, to complete the promise 

 ■which I made in the preliminary remaiks to this essay. 

 If 1 do not so regularly hereafter furnish my numbers, 

 1 hope the busy season of the spring wiii palliate my 

 omission. Sylvanus.
