has withered, the apex of the style splits and expands its lobes.

WATER FROM EUCALYPTUS roors.—In many parts of Australia, 
where water is scarce, the natives formerly procured it from the 
roots of the Eucalyptus and a few other trees. The tree most 
preferred throws out numerous lateral roots, which lie at a depth 
of from six to twelve inches below the surface. According toa 
writer in the Proc. Linn. Soc. of N, South Wales (Vol. viu, 1883), 
the native having ascertained, by means of prodding with a 
pointed stick or spear, the position of some of the roots, ` re- 
moves the superincumbent soil with his wooden shovel for twenty 
‘or thirty feet, and cutting the root off at each end lifts it out of 
the trench and cuts it up into lengths of about eighteen inches or
