109 EUCALYPTUS GLOBULUS 



The influence of Eucalyptus trees in this respect is commonly 

 regarded as being serviceable in two ways first, by the far- 

 spreading roots of this gigantic tree acting like a sponge, as it 

 were, and thus pumping up water and draining the ground ; and 

 secondly, by emitting odorous and antiseptic emanations from its 

 leaves. The more important influence is doubtless the power 

 which the roots possess of absorbing water from the soil, so that 

 when thickly planted in marshy places " the subsoil is drained in 

 a little while as though by extensive piping /' but some influence 

 is also exerted by the emanations from the. leaves, which 

 experiments have recently shown have marked antiseptic pro- 

 perties, and power of destroying the injurious effects of paludal 

 miasm.
