 and others in Scotland, which caused various land- 

 owners to follow their example in North Britain.

 being natives of North America. Of these, three- 

 fourths were shrubs, the trees consisting chiefly of 

 pines, oaks, poplars, maples, and 'thorns, fresh varieties 

 of trees which had been introduced before. 



Many of the new timber trees from North-west 

 America, which were introduced by Douglas in the 

 first half of the present century, from the enormous 

 size they attain in their native country, are expected 

 to become very valuable as timber here, but in the 

 case of these kings of the forest, it is somewhat hard 

 that the results cannot be judged in the case of 

 one man's lifetime, and the introducers have to con-

 ultimately attain ; for trees are pointed out which are 

 said to have stood from the time of the Conquest, and 

 although there is doubtless much exaggeration in the 

 ages of r many celebrated trees in different parts of 

 the country, there are well authenticated instances of
