The numbers, taken by centuries, are, in the 16th century, 89 ; 

 in the 17th, 131; in the 18th, 445; and, in the first [three de- 

 cades of the 19th, 699! The total number of foreign trees 

 and shrubs introduced up to the year 1830, appears to be about 

 1300; or, probably, up to the present moment, including all 

 those species which have not yet flowered, and, consequently, 

 have not yet been recorded in books, about 1400. 



The countries from which these 1 300 species have been intro- 

 duced appear, from the Hortus Brita?micus i to be as under : — 



Europe; Greece, Turkey in Europe, and the Levant, 36; 

 Italy, 35; Sicily and other Mediterranean islands, 19; Spain, 

 69; Portugal, 12; Switzerland, 49 ; France, 34; Germany, 52; 

 Hungary, 46; Russia, 41 ; Sweden, 4 ; Lapland, 4 ; Spitsber- 

 gen, 1; North of Europe, 2; Central Europe, 18; South of 

 Europe, 111: in all, 543. Asia: Siberia, 69; Asia Minor, 3; 

 East Indies, 4; Nepal, 54; China, 34; Japan, 11; Persia, 5; 

 Asia, 3 : in all, 183. Africa and the Canary Isles: Barbary 

 States, 13 ; Egypt, 3 ; Cape of Good Hope, 4 ; Canary Isles, 3 : 

 in all, 23. America: North America, 528; Mexico, 4; South 

 America, 22 ; Straits of Magellan, 6 : in all, 560. Australia 

 and Polynesia : New Holland, 1 ; Van Diemen's Land, 2 ; New 

 Zealand, 1 : in all, 4. 



It would thus appear, that nearly half the foreign trees and 

 shrubs in the country have been introduced during the pre- 

 sent century ; and that these have been brought chiefly from 

 North America. Among them there are not more than 300 

 trees which attain a timber-like size, and of these by far the most 

 valuable is the larch. Some of the European acers, the sweet 

 chestnut, some oaks, some poplars, pines, and firs, and the pla- 

 tanus 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 ; but by far the finest
