835 EXPERIMENTAL FARMS 



7 GEORGE V. A. 1917 



The chief broad-leaved trees are: (1) Elm, this is perhaps the best shade and 

 ornamental tree in Manitoba; (2) Ash, rather open, for a shade tree, but good in 

 mixed plantations; (3) Basswood is very ornamental and has proven quite hardy at 

 this Farm; (4) Birch succeeds well, and is ornamental. A fine tall specimen of cut- 

 leaved weeping birch is frequently commented upon by visitors. Several bushes of 

 low birch are also thriving well; (5) Ginnalian Maple — very ornamental, especially 

 in the fall. This is very desirable for hedges; (6) Poplars. These are very rapid 

 growers, and tower above the other trees in the arboretum. They are not long lived, 

 several are already showing rot. in the trunks. A few varieties found here are: 

 Populus petrowshiana, P. fastigiata, P. Simonii, P. angustifolia, P. tremiiloides, P. 

 halsamifera. The poplars are good for shelter belts, mixed with other more permanent 

 varieties, as they are quick growers. They are very hardy. (7) Willows. These 

 are more hardy and quick growing. Some, such as the laurel-leaved willow, are very 

 desirable as avenue and ornamental trees, as they grow up with a clean trunlv, and 

 a symmetrical top. They are also very resistant to insect attack. (8) Ash-leaved Maple, 

 has until recently, been a general favourite, as an avenue or shade tree. It is quick 

 growing and hardy, but very liable to insect attack. This tree should be abandoned, 

 as an avenue tree, in favour of the more graceful elm, or the hardy laurel-leaved 

 willow. 



Other species growing in the arboretum, and showing the necessary degree of 

 hardiness are: Oak, Ironwood, Smooth Sumac, Silver Maple, Native Alder and 

 Buckthorn (three varieties). Flowering trees and shrubs are dealt with below.
