propagated by seeds, and the young plants should 

 have a fairly moist position with plenty of leaf- 

 mould or peat to grow in afterwards. 



SEQUOIA The two species of Sequoia should 

 be raised from seed, and the three or four varieties 

 be grafted on the type species. 



CRYPTOMERIA. This only contains one species, 

 viz., C. japonicay which can only be obtained from 

 seed, or by cuttings ; and the varieties root readily 

 as cuttings, though one or two of the weaklier ones 

 do better if grafted on C. japonica. 



ARAUCARIA. Propagate by seeds, which, though 

 sometimes difficult to obtain, germinate freely and 

 quickly. 



TSUGA. The Hemlock Spruces are easily and 

 quickly obtained from seeds, and one or two will 

 strike from cuttings ; the varieties do best when 

 grafted on the species they belong to, though T. 

 pattoniana var. glauca, more commonly known as 

 Abies hookeriana, will come fairly true from seed, 

 about 75 per cent, being the usual quantity if the 

 seed is obtained from good plants. 



PiCEA. This genus has been mentioned before 

 as being commonly grafted on P. excelsa (the 

 Common Spruce), which is an easy way of obtain- 

 ing young plants, which, however, cannot be recom- 

 mended to form good specimens in after years. 

 The species of Picea should all be raised from seed, 

 and the many named varieties of P. excelsa should be 

 grafted on the parent species. At least one-half the 

 plants of P. Engelmanni var. glauca and P. pungens var.
