" Catalogue OF THE Trees and Shrubs in the Arboretum and 

 Botanic Garden at the Central Experimental Farm, Ot- 

 tawa, Ontario, Canada." By Wm. Saunders, LL. D., F. R. 

 S. C, F. L. S , Director of Experimental Farms, and W. T. 

 Macoun, Horticulturist of Central Experimental Farm and 

 Curator of Arboretum. Bulletin No. 2, second series, June, 

 1899." 



In the preface to this catalogue the writers give a short ac- 

 count of the work done in the Arboretum and Botanic Garden of 

 the Central Experimental Farm since its establishment in 1887. 

 From it we learn that no trees or shrubs were planted until 1889 

 when 200 species were set out followed by additional species each 

 year, until in 1894 the number had reached 600. During the past 

 five years special attention has been given to this branch of the 

 work done at the Central Farm, the total number of species and 

 varieties catalogued amounting to 3,071. Of these, according to 

 the foot-note on the last page of the catalogue, 1,434 have been 

 found to be hardy ; 361 halt hardy ; 232 tender ; 307 winter killed 

 and 737 have not been planted long enough to admit of an opin- 

 ion being given as to their hardiness. 



Under each species the date of planting is given as well as the 

 degree of hardiness, and this with the alphabetical arrangement of 

 species which has been adopted will enable anyone to learn at once 

 whether a plant is hardy or not in this region. Apart entirely from 

 its scientific value the catalogue will be of great service to all plan- 

 ters of trees and shrubs in the latitude of Ottawa. The nomen- 

 clature of the "Index Kewensis " and " Kew Guide " has been 

 adopted, but care has been taken to include in the synonymy the 

 names under which some of our North American soecies are more 

 generally known. 



The arrangement of the catalogue is excellent and in complete- 

 ness and general usefulness it is by far the most valuable publica- 

 tion of its kind that has been issued in America.
