NOTICES OF AUTHORS, 



of entire failure. The soil requires to be rich, and 

 is benefited by a dressing of well-made manure pre- 

 vious to sowing. 



Sycamore Plane braird also suffers by late frost, 

 and for greater security ought also to be sown part- 

 ly in March and partly in April. Planes require 

 dry, poor, rather exposed sandy soil, for seed-bed ; as, 

 in rich damp soil, the top of the annual shoot does 

 not ripen : the seed ought to be thinly sown. 



Birch and Alder seeds require to be sown in 

 March, or beginning of April, on very fine, rich, 

 easy mould, giving them very slight cover, especially 

 the birch. 



The Coniferse, Scots Fir, Spruce, Silver Fir, &c. 

 should be sown in April, on very rich easy soil. The 

 greatest care is required to deposit these different 

 seeds at proper regular depth, from an inch to the 

 fourth of an inch, in proportion to the size of the 

 seed. 



Larch should also be sown in April ; it succeeds 

 best on the clean mellow ground which has produced 

 a crop of seedling Scots fir. It is worthy of remark, 

 that the larch seedlings and row-plants are liable to 

 die under a putrescent disease, when much recent 

 manure is employed.— We remark this accordance 

 with its tendency to putrid disease in after life.
