Pimis Laricio, Poir. — British foresters draw a much sharper 

 line of distinction between this tree and P. austriaca, Hoess., 

 than appears to be the case with Continental foresters. P. 

 Laricio has been a good deal planted for ordinary commercial 

 purposes, especially on strong land and chalk, where it shows 

 more rapid growth than the Scots Pine. It is credited with 

 resisting the attack of rabbits better than most trees. Perfectly 

 hardy : —

Pinus monticola, Dougl. — Perfectly hardy and grows rapidly, 

 but so much affected by Cenangium abietis as to be threatened 

 with extermination in many districts. Apparently this disease 

 has spread with great rapidity during the past few years, there 

 being no report of its ravages in the many communications that 

 Mr. Dunn received for the Conifer Conference in 1891 : —
