are used the easier it is to plant the trees in the best proportion of each kind of 

 tree. 



In some of the clumps of single species the disadvantage of not having two or 

 more kinds mixed is quite as apparent as the disadvantage of having so many kinds 

 nlixed in the mixed belt. Ash, butternut, black walnut, and elm, which have thin 

 foliage, do not kill the sod when young, and the growth on this account is checked. 

 If other heavy foliaged kinds, such as larch, spruce, pine, or box elder, had been mixed 

 with these the results would almost certainly have been much better. 



The forest belts afford many interesting studies of the relative shade-endurance 

 of different species. 



From 1890 to 1894 the distribution of young forest trees, cuttings and scions to 

 the Western provinces was made through the Horticultural Division, and during that 

 time 7,213 packages in which were nearly half a million trees and cuttings were dis- 

 tributed. 



ARBORETUM AND BOTANIC GARDEN. 



The Arboretum and Botanic Garden which occupies 65 acres of land, has been in 

 charge of the writer since 1895. In 1898 when he became Horticulturist he was 

 appointed Curator of it, since which time it has been included in the Horticultural 

 Division. Previous to 1895 the Arboretum and Botanic Garden had been in charge 

 of Dr. Jas. Fletcher, Botanist and Entomologist of the Dominion Experimental Farms. 

 The collection of trees, shrubs, and herbaceous plants is now very large. In the 

 autumn of 19Q5 there were 3,229 species and varieties of trees and shrubs, represented 

 by 5,010 specimens ; and 2,041 species and varieties of herbaceous perennials. A num- 

 ber of these have doubtless been killed by the winter of 1905-06, but the additions 

 which will be made in 1906, will probably make the number aboiit equal to what it 

 was in the autumn of 1905. This large collection of plants from many parts of the 

 world furnishes a valuable object lesson as to the species which will endure the climate 

 at Ottawa, and also gives a good opportunity for the study of the different species and 

 varieties. 



Notes are recorded annually on the hardiness and vigour of the plants, and in 

 the case of the herbaceous perennials their time of blooming, continuity of bloom, 

 colour of flowers and height of plants. 



A catalogue of the trees and shrubs in the Arboretum was published conjointly 

 by the Director and the Horticulturist, in which the scientific names of the trees and 

 shrubs are arranged alphabetically with many of the common names, and notes on 

 the relative hardiness of the most of the speciments given. The countries of which 

 the trees and shrubs are native are also published in this bulletin. 



The following articles relating to the plants growing in the Arboretum and Botanic 

 Garden have been published in the Annual Reports of the Horticulturist. 



1898, List of Additional Herbaceous Perennials, (a list of one hundred of the best 

 had been published in the Annual Report for 1897). 



1899, List of Additional Good Perennials. The best low growing shrubs. 



1900, A Descriptive List of the Best Woody Climbers. 



1901, A Descriptive List of the Different Species and Varieties of Lilacs. 



1902, A list of Best Spring Flowering Perennials. 



1903, A List of Deciduous Trees, Shrubs and Climbers with Attractive Foliage, 

 Bark and Fruit. 



1904, A List of the Genera of Trees and Shrubs in the Arboretum, with the Num- 

 ber of Species of each.
