1902] Macoun Notes on the Arboretum. i2q 



stated that other specimens of these had been killed out root and 

 branch. These furnish excellent examples of the individuality of 

 trees. We have noticed over and over again in nursery rows, 

 that some trees of the same species are hardier and more vigorous 

 than others. It has also been noticed that a tree which has a wide 

 range from north to south, will not be as hardy when imported 

 from the south as from the north. An excellent example is the 

 Red Maple, Acer rubnim. This tree imported from some parts of 

 the United States has killed back and made scrubby trees, while 

 from further north it has done well. 



There is no doubt, in the writer's opinion, that many trees 

 which we have great difficulty in getting to fruit here, will eventu- 

 ally be much hardier when raised from seed ripened at Ottawa. 



Much could also be said and written of the herbaceous 

 perennials which make such an attractive and useful feature of the 

 Botanic Garden from early spring until late autumn. The collec- 

 tion is growing rapidly and the information regarding the different 

 species and varieties when grown in this climate is getting more 

 valuable every year. 



The Arboretum and Botanic Garden is a public institution and 

 should be made use of by the public. Every assistance will be 

 fully given to those who desire to study the plants growing there, 

 and it is hoped that this paper will induce some of the members of 

 the Ottawa Field Naturalists' Club to make a closer study of trees, 

 shrubs and herbaceous plants in cultivation than they have done 

 in the past. 



Contributions of plants and seeds, especially of rare Canadian 

 species, will be gratefully received, as the desire is to increase the 

 collection as rapidly as possible and to have the native flora well 

 represented.
