The hazel grows best upon what is called a hazel mould, that is to say, 

 a reddish brown calcareous loam ; but it will grow on any soil, from a chalk 

 or gravel, to a cold and wet clay : the rods are durable in proportion to the 

 dryness of the ground on which the hazel grows, and they are particularly 

 good where the bottom is chalk. The situation most favourable is on the 

 sides of hills, for it will not thrive in a soil where water is stagnant : though, 

 like all trees and shrubs that grow in dense masses, it requires a great 

 deal of moisture ; and, indeed, it will always keep the ground moist under it 

 by the denseness of its shade, The species is propagated by nuts, and the 

 varieties by layers. The nuts may be dried in the sun. and preserved in a 

 dry loft, covered with straw, or in sand, till the following February ; when they 

 may be sown, and treated in the same manner as mast or chestnuts.
