ON SOME N.S/W. 1 AX-SUBSTANCES. 189 



■connected with the sample of R. rhodanthema, as already detailed, 

 this colour-test is most encouraging. And even if colonists are 

 not enterprising enough at present to cultivate this New South 

 Wales Sumach tree as a tan-material, they will certainly carefully 

 collect the valuable leaves of such trees as already are to be found 

 in the Northern Districts whenever one is felled for the sake of 

 its ornamental timber, and take measures for judiciously pruning 

 those which self-interest will warn them not to destroy.
