THE NURSERY. 



The ash and the plane may be sown in March, 

 and then- seeds should be covered from half an inch 

 to three quarters of an inch deep. The seeds of the 

 former require to be two seasons in the ground be- 

 fore they germinate. It is proper, therefore, before 

 sowing them in the nursery, to keep them in a 

 heap, covered with earth, for a twelvemonth pre- 

 vious. 



The sweet-chesnut and the horse-chesnut may be 

 sown at the same season as the last. They should 

 be covered an inch deep. I might have mentioned 

 the oak, as requiring similar treatment ; but it, as 

 we will have afterwards occasion to shew, ought ne- 

 ver to be sown in the nursery at alk 



The beech, being extremely subject to injury from 

 frost, when it newly comes up, should not be sown 

 earlier than April. Though its seeds are of a con- 

 siderable size, they should not be covered deeper 

 than half an inch. 



The seeds of ehn may be either sown in June, 

 when they are gathered from the trees, in which 

 case part of them will come up immediately, and 

 the remainder, consisting of the greater number, 

 next spring ; or they may be kept dry till the 

 March following, and sown then. They should be 

 covered between a quarter of an inch and half an 

 inch deep.
