 The Silver Wattle. 



A tree spreading rapidly by numerous root-suckers. The wood is . 

 moderately hard, light brown, but warps considerably. Pores small, 

 rtrn in short linear groups. Medullary rays short, fine and moderately 

 broad, well marked on a radial section. 



Indigenous in New South Wales, Victoria and Tasmania. Introduced on the 

 Nilgiris, and now naturalised since IS in. 



The wood is extensively used in Australia for timber, and the bark for tanning. 

 It is Ivinij tried in plantations in the lulls of the Punjab, North- Western Provinces 

 and Sikkim. Our specimen \v;is cut from a tree 11 years old and 46 feet high, and was 

 ahout 12 incites in diameter. Colonel l>eddome, in his Report on the Nilgiri plantations 

 ol April 1S7S. says that, this Wattle <;rows very readily from the stool, but comes up 

 in a deiiM- mass of small t wig-like stems, : M> that it can only be depended on for 

 mall firewood.
