grounds, where one plant still survives. It is of small 

 stature, rather a large shrub than a tree, but its white bark, 

 its peculiar light green foliage and its beautiful spikes of 

 green and red samaras in autumn, entitle it to attention as 

 an ornamental plant. It is easily cultivated and an excel- 

 lent shrub for hiding palings or other unsightly objects. 



22. The Xorway Maple. Acer platanoides. 



Several specimens of this tree were presented by the 

 Hon. Mr. Young, and it proved the finest of all those given 

 by him as an ornamental tree. Our only remaining 

 example is that near the Peter Eedpath museum. This 

 tree somewhat resembles our sugar maple, to which it is 

 nearly allied, hut it has larger and deeper green foliage, is 

 earlier in putting forth leaves in spring, and retains them 

 longer in autumn. It seems perfectly hardy, and is in all 

 respects one of the finest ornamental trees from abroad ever 

 introduced into this country. A seed bed was established 

 for the sake of propagating plants for distribution ; but the 

 plants had to be removed owing to building operations. A 

 number of them, however, still exist in care of Prof. 

 Penhallow. 



No tree better deserves the attention of arboriculturists. 

 It would probably yield sugar, but I am not aware that its 

 properties in this respect have been tested. 



23. The English Maple. Acer campestre. 



This very beautiful small-leaved maple was introduced 

 by Mr. Young, and a number of specimens were planted on 

 the grounds. All those on the richer and less sheltered 

 ground were so much winter-killed that in a few years they 

 perished ; but a few plants which happened to be put on 

 the dry terrace, sheltered by the buildings, have held their 

 ground, not however as trees, but as shrubs. Their beauti- 

 ful and singular foliage always attracts attention. It is 

 deep green in summer and pale yellow in autumn. They 

 have never borne fruit, and every spring require pruning
