the effect, and it is astonishing he did not 

 search for the cause. 



If the fourth rate or high wind of five 

 pounds pressure upon a square foot occurs 

 but twice or three times in a year, it is 

 needless to describe the effect of it upon plan- 

 tations which have been too much thinned. 



It might be asked whether the wind is asN 

 strong on the European Continent as it often 

 is in these islands ? Navigators describe the 

 calms and prevailing winds in certain parts 

 of the ocean ; and Humbolt, in describing the 

 forest of Oroonoko, states, 'Uhat the breeze, 

 if ever it be felt, blows only after sunset," (vol. 

 5, p. 68). And again, "no breath of wind 

 ever agitates the foliage." In those regions, 

 the species of spruce described by Lewis and 

 Clark, and also by Douglas, may ascend to 

 the greatest height possible, from their not 

 being moved or injured by winds. Hence, the 

 immense length of such trees is accounted for, 

 and it ceases to be a subject to excite wonder.
