16. Notice of some Forest and Ornamental Trees tvhich deserve 

 the Attention of Scottish Cultivators. By Gilbert Laing Mea- 

 son, Esq. 



M. Andre Michaux noted to Mr. Laing Meason the fol- 

 lowing trees and shrubs, as deserving the attention of gentle- 

 men in Scotland : -*- 



i?etula papyracea, the paper or true Canadian Canoe Birch. 

 A tree of rapid growth, excellent timber, large, and highly 

 ornamental. 



jfraxinus americana, White American Ash. Quicker in 

 growth than the common ash ; but the young wood apt to be 

 injured by the winters in Scotland. 



Pinus laricio, the Laricio or Corsican Pine {Gard. Mag., 

 vol. i. p. 79.), found also in the Pyrenees. " It is a very hand- 

 some tree, assuming more the habit of a deciduous forest tree 

 than of the pine or fir class. The wood is said to be good, 

 and the growth is quick." 



7 v lex chinensis, Chinese Holly. Of rapid growth ; leaves 

 small, and without spines ; well adapted for division hedges in 

 flower-gardens. 



Orme de Siberie, or Siberian Elm. " This is an excellent 

 fast-growing tree, possessing the quality of toughness in a 

 degree superior, perhaps, to any other tree in Europe ; at 

 least, from repeated trials, it has been found in France to be 

 one of the toughest and most elastic of woods. I have planted 

 a few specimens, which thrive vigorously in a strong soil in 

 Forfarshire. The tree grows to a considerable size, and is 

 quite distinct from the t/'lmus piimila, which is often called 

 Siberian Elm in our nurseries." 



Bourgene de Canadie ? " An evergreen that has proved 

 itself in France to form an excellent hedge." "We shall be 

 much obliged to our correspondent M. Soulange-Bodin for 

 the scientific names of this shrub and the preceding tree. 



Juglans alba americana, White American Walnut. A fine 

 large tree, of much quicker growth than the common walnut. 

 Tilleul argente de Constantinople, Silvery Constantinople 

 Lime. A fine tree, with delightfully smelling flowers; pro- 

 bably the Tilia argentea of Waldstein and Kitaibel. 



17. Notice of the Hardy Fruits of Upper Canada. By Mr. Tho- 

 mas Blair. 



The apples in the orchards are particularly fine : they are 

 all raised from seed ; and, though many of the trees produce
