below it and becomes at once the home of a black fungus. 

 This materially injures the appearance of the olive and 

 markedly diminishes, and even destroys, its normally beau- 

 tiful silvery foliage. 



The lace wing fly, or one of the ladybirds has, with me, 

 destroyed the black scale on my olives. The scale is not 

 exterminated, but persists in such small number as to be 

 unnoticeable. It may be that some other enemy helps keep 

 the scale down, but the little bored holes in the scale 

 show the lace wing's work to be important. 



The timber of Eucalyptus polyanthema is useful, being 

 very tough and hard to split. The tree is a moderate grower, 

 and it is reported by Von Mueller to have withstood the 

 out-door temperature of Kew. To these material advan- 

 tages it adds a unique beauty. The habit of growth of this 

 Red box is also graceful, each leaf being attached to the 

 branch by- a slender stem. 



This tree at Mr. Scharff's, in South Pasadena, has done 

 well, and the specimens at Santa Monica are vigorous and 

 attractive. It deserves a wider attention than it has 

 received. The seeds can be obtained from any of the trees 

 named. 



EUCALYPTUS LONGIFOLIA. 



Eucalyptus longifolia is a persistent barked, moderate 

 sized tree, native to the New South Wales plains, between 

 the Coast and the Blue Mountains, which climatically cut 

 that portion of Australia in such distinct divisions. It is 

 called the Wooly Butt and is mainly used for fuel. It is 

 named for its exceptionally long sickle shaped leaves which 

 at times are found even over a foot in length. Here
