146 The Forest Trees of America. 



1 Evergreen tree from 60 ft. to 80 ft., the Scotch Pme. 

 3 Evergreen trees, the box, yew and holly. 

 91 Deciduous shrubs and very low trees. 



12 Evergreen shrubs from 5 ft. to 15 ft. 

 1 Evergreen climber, the ivy. 



14 Deciduous trailers, brambles, &c. 



13 Evergreen shrubs from 6 in. to 1 ft. in height. 

 10 Deciduous shrubs of similar size. 



These, it appears, are all that are indigenous to Great 

 Britain, and, as Mr. Loudon observes, "that there are few 

 trees and shrubs which are indigenous to the North of France, 

 Belgium, and the North of Germany, which are not natives 

 of Britain," the number indigenous to Northern Europe is 

 but little beyond the above number. 



From tables exhibited by Mr. Loudon, it appears that there 

 were introduced into Great Britain from 1548 to 1830, about 

 1300 foreign trees and shrubs, viz. : — In the ] 6th century, 89 ; 

 in the 17th, 131 ; in the 18th, 445; and in the 19th, (up to 

 1830,) 699 ! 



Of this large number, Europe furnished 543 ; Asia, 183 ; 

 Africa and the Canary Isles, 23 ; Australia and Polynesia, 

 4 ; America, 560, of which 528 were from North America ! 



" It would thus appear," remarks Mr. Loudon, " that nearly 

 half of the trees and shrubs in the country have been intro- 

 duced during the present century ; and that these have been 

 brought chiefly from North America. Among these are more 

 than 300 trees which attain a timber-like size ; and of these, 

 by far the most valuable, is the larch. Some of the Euro- 

 pean acers, the sweet chestnut, some oaks, some poplars, 

 pines and firs and the platanus and cedar from Asia, are also 

 valuable as timber trees ; but the chief accessions to this class 

 are the acers, oaks, elms, ashes, poplars, birches, pines and 

 firs of North America. Our principal fruit trees are from 

 Asia, including the common walnut, which is both a fruit 

 and a timber tree ; hut by far the finest ornamental trees and 

 shrubs are from North America. Our greatest hopes for 

 future introductions are from the unpenetrated regions of 

 North America, and from the mountainous regions of Asia 

 and New Zealand."
