ARBORICULTURE. 335 



Acer, This genus requires a deep, rich, moist soil free from 

 stagnant water : some species will thrive in a dryer soil. The 

 seeds should be sown as soon as possible after they are ripe. 

 Some are of opinion that they should be preserved in dry sand 

 until March or April. 



Alnus. This genus requires a moist, damp soil. The seeds 

 should be sown in autumn or spring : if left until spring, they 

 should be preserved in dry sand. 



Andromeda. The seeds of this genus should be sown as soon 

 as ripe in a sandy peat. 



Betula. This genus will grow in every description of soil, 

 from the wettest to the driest. The seed may be sown in 

 autumn or spring ; to be kept in a dry, cool sand, from the time 

 it is ripe until it is sown. 



Carpinus. Poor clayey loams, incumbent on sand and 

 chalky gravels, are well adapted for the growth of this genus. 

 The seed should be sown in autumn. 



Castanea. A rich sandy loam raises the chesnut to the 

 greatest perfection as a timber tree ; but it appears to come to 

 great maturity in clayey soils, if free from stagnant moisture. It 

 will thrive also in gravel or sand, if not in too bleak or exposed 

 a situation. The seeds should be planted in March or April. 



Chamcerops. This genus requires a warm, rich garden mould. 

 The seeds should be sown at their maturity. 



Cupressus. This genus delights most in a sandy loam, but it 

 will also thrive and grow to a considerable height in clayey soils. 

 The seed should be sown in the spring, in a warm situation, or 

 in pots, in dry, light earth : to be kept in the cones until the 

 period of sowing. 



Diospyros. The seeds of this genus should be sown at their 

 maturity in a sandy loam. 



Gleditschia. This genus requires a sandy loam : its seeds 

 should be sown as soon as they are matured : they frequently 

 remain in the earth two years before they vegetate. 



Juglans. This genus requires a rich, loamy soil to bring it to 

 perfection ; but it will succeed in very light, siliceous, sandy 

 soils, as well as clayey ones. The nuts should be preserved
