174 EUCALYPTUS. 



Eucalyptus sideroxylon (Victorian ironbark) suited to 

 wheelwrights' work. Does well in South Australia. Mr. 

 Gill speaks of the bark of sideroxylon as persistent on all 

 the branches as well as on the main stem. (This does 

 not seem to be the case in California). Little tree planting 

 seems to have been done in Australia outside of this 

 colony. 



In Algiers the very considerable tree planting under the 

 French Forest officers, notably "Cordier,'' has been largely 

 of Eucalyptus. This is also the case in the Argentine 

 plantations. In fact where the Eucalyptus will grow there 

 is no tree to compare with it in cheapness of handling and 

 rapidity of growth. Besides these advantages trees of this 

 genus are generally resistent to all forms of insect pests, 

 more so indeed in foreign lands than in their own native 

 haunts. Eucalyptus amygdalina variety angustifolia is 

 often subject in California to willow scale. This scale is 

 sometimes found on the fruits of other species but not on 

 the trees themselves. Where the temperature is not too 

 cold the Eucalyptus will always be the most popular and 

 the most advantageous tree for grove or forest plantings. 



HOW TO MEASURE THE HEIGHT OF A TREE, 



Start from the trunk of the tree at a point about as 

 high as the eye of the observer and measure out a distance 

 according to convenience, which should preferably be 

 greater than the supposed height of the tree. At this 

 point a stake should be set, the top of which must be at 

 the same elevation from the ground as the point on the
