PART FOURTH. 



CLASSIFICATION OF SOILS IN REFERENCE TO THEIR VALUE. 



I. ON THE PRIMARY DIVISION OF LAND FOR VALUATION 



PURPOSES. 



All lands are divisible for the purpose of valuation into 

 four great orders, viz. : 



1. Arable land. 



2. Grass land. 



3. Timber land. 



4. Bog land. 



Arable land comprises all that is cultivated or better 

 adapted for cultivation than grazing. 



Grass land is meant to include all pasturage and mea- 

 dow, from the finest fattening parks of our most favoured 

 districts, to the exposed and irreclaimable wastes of moun- 

 tain herbage. 



Timber land includes all forests and young plantations. 



Bog land, though strictly embracing every description 

 of soil in which peat is a principal constituent, is con- 

 fined here, for valuation purposes, to those varieties only 

 which are cut for turf. 



II. OF THE CLASSIFICATION OF ARABLE SOILS. 



Arable lands are divided into the following classes, for 

 the purposes of valuation, viz. : 



1. Extra soils, comprehending town parks and all lands 



possessing, either from their nature or situation, 

 peculiar advantages which enhance their value. 



2. Prime soils, comprising all superior lands capable 



of growing wheat and the other cereals to per- 

 fection. 



3. Medium soils, comprising lands of moderate depth 



and productiveness.
