be sown in April, on finely-prepared soil. 

 After the seeds are sown, a light roller should 

 be drawn over the bed, to press the seeds 

 firmly into the earth, and they should then 

 have a thin covering of soil. . The plants are 

 generally allowed to remain ,two years in the 

 seed-bed, and afterwards planted into nursery 

 lines, or where they are finally to remain. As 

 the Larch vegetates earlier than most other 

 trees, and suffers more if removed after it has 

 begun to grow, it ought to be transplanted in 

 autumn, or early in spring. We have adopted 

 the names of the species and varieties as given 

 by Mr. Loudon in his very valuable work, the 

 Arboretum et Fruiicetum Britannicum. Syno-
