further investigations. The Coast douglasia is a 

 rapid-growing, shade-tolerating species which 

 combines the peculiarities of both fir and spruce, 

 while its root system adapts itself readily, accord- 

 ing to Mayr, with the given conditions of the 

 soil. On the other hand, it is not a kind of tree 

 adaptable for poorer pine soils than Classes II. to 

 III. In its early years it is susceptible to early 

 frosts on account of its late after-growth (Sep- 

 tember), but as regards late frost it stands, in its 

 demeanour, between fir and spruce. In the 

 severe temperature of winter it suffers from 

 browning of the needle, needle-shedding, and 

 killing of chlorophyl. It is, consequently, suitable 

 in moist atmospherical situations such as have 

 been already mentioned in connection with the 

 Chammcyparis lawsoniana. Warm, open plains, 

 with their contrasts in temperature, should be 

 avoided. Pure plantations can be made on cold 

 areas, when these slope to the south-east or east, 

 or north and north-west, up to an altitude in 

 which the fir appears pure. In low-lying places 

 some slight protection by copse or the stool shoots 

 of broad-leaved and coniferous trees is desirable. 

 The Coast douglasia develops best in groups 

 amongst broad-leaved coniferous trees introduced 

 before or after their reproduction. It is also 

 adapted for filling up bare patches where it is 

 planted singly. Close planting, that is one plant
