CENTRAL STATION TREE-PLANTING ON A HILLTOP.

In 1888 some Acacia decurrens were added to the plantation, and a few 

 miscellaneous trees, most of which died. In 1892 a row of Eucalyptus 

 corynocalyx, or sugar gum, and in 1892 some Eucalyptus globulus were 

 planted here. The latter were set at a considerably higher point, or at 

 nearly 900 feet elevation. All these trees have been subject to pasture 

 conditions, have received no care nor cultivation, and hence can not be 

 said to give an exaggerated idea of the growth that might be expected 

 on such Coast Range slopes as these. 



PLATE 18. E. GLOBULUS IN ADOBE SOIL OF HILLTOP. 



The growth of the common blue gum, Eucalyptus globuluSj now ten 

 years planted, is greater than that of any other trees tested. Four trees 

 standing near the crest of the hill, at an elevation of nearly 900 feet 

 above the sea (or 785 feet above the Oxford street entrance to the Uni- 

 versity grounds), now show an average girth of 28 inches. The largest 

 girths 33 inches. They are from 40 to 45 feet high and were planted 8
