2. Trees ivith Ornamental Flowers. — In making the 

 following grouping, arranged according to relative 

 hardiness, it has been impossible to give precise in- 

 formation as to the exact degree of frost-tolerance of 

 the several species, as we can find but meager published 

 data on the subject. 



A. Susceptible to light frost. 

 The following would probably succumb to a tempera- 

 ture of 28° Fahr. : 



Encalyptus ealophyUa. 

 Eucalyptus ficifolia, 

 Jacaranda ovalifolia. 



AA. Susceptible to heavy frost. 

 The following are not likely to stand a temperature of 

 20° Fahr. Some of them may succumb at 25° Fahr., 

 particularly while young:

4. Wide-spreading Trees for Shade, Mostly ivith 

 Ttounded Outline. — It frequently happens that the 

 owner of a garden desires a wide-spreading tree in the 

 back or one corner of his domain, under which to 

 swing a hammock on a hot day; such trees are also 

 useful in the school yard, affording welcome shade in 

 which the children can eat their lunch. 



A. Deciduous, all hardy. 



B. Growth rapid or medium. 



c. Suckers likely to be troublesome.
