 green form succumbs to frost, the bhie form from Colorado is 

 hardy, although relatively to the green slow, grows faster than 

 spruce in some locations, the form from British Columbia has 

 not thrived ; in the hill country the green variety seems to hold 

 its own. Picea sitchensis is only fit for the mildest locations; 

 Piccea pungeus, valueless. Pinus banksiana (divaricata), the 

 same. Pinus Strobus suffers much from game, besides from 

 Peridermium and Lyda campestris, but is resistant to drouth and 

 frost and is soil improving. Larix Icptolepis suffers from drouth 

 more than the native, its resistance against the larch disease is 

 its best recommendation. CJiamaecy paris laivsoniana needs high 

 degree of humidity and side protection, suffers from game and 

 is given to form double leaders. The most successful species has 

 been Quercus rubra on poorer soils than the native thriving and 

 grovv^ing rapidly, also Populus canadensis in overflow lands.

AI. Canon advocates fire lines planted to 

 Novel Fire a shrub called "Mille pertuis," which is 



Protection said to resist fire, to grow densely up to 



18 inches in height, and to remain in foli- 

 age the entire year. Canon advocates the use of this shrub in 

 central France for covering fire lines. This presents a new idea 

 which might be applied on this continent.
