Pin. 418.; C. A. grandis Lodd. Cat. ed. 1836; the Cob Nut, syn. 
the Barcelona Nut, Downton large Nut, &c., Hort, Soc. Cat. No.

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 ina 
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,
