 of the parasite and its host. 



Trees are very sensitive to their environment, and 

 mould the effects of their surroundings into their 

 growth. The stunted firs and spruces at the edge of 

 the Bay of Fundy are permanent witnesses to the 

 terrible winds and storms of past years ; every bough 

 and twig reaching landward, away from the path of 

 the blasts. Canadian balsams often orow so close to-

 impossible for even a rabbit to creep between, and here 

 we see everywhere signs of the warfare which goes on 

 in the forest. 



The reverence which we pay to age should not be

 thous'ht of admiration when we consider the centuries 

 of constant struffffle ao-ainst animate and inanimate 

 foes, by which alone it has maintained its place and 

 prestige. The great wild fig-trees, which are sometimes 

 overcome by choking vines, occasionally begin life in 

 a most novel way. A favourite nesting-site of wood- 

 peckers is in the soft, pulpy branches of the organ 

 cactus. If it hajjpens that a seed of the fig-tree be-
