The lowest real value is thus shown by the Scottish seed, be- 

 cause, unfortunately, the Scotch have the same bad habit as the 

 Japanese in the case of the Japanese Larch, of collecting most of 

 the cones as early as possible and therefore obtaining them before 

 they are ripe. In a markedly insular climate, like that of Scotland, 

 where there is much cloud and little bright sunshine, it is neces- 

 sary to be doubly cautious in regard to premature collecting. It 

 is true that the period of growth of the summer season is fairly
