10 Select Plants for Industrial Culture and 



was got from one tree at Tambo, without stripping all the branches. 

 The height of this tree was 60 feet, and the stem 2 feet in diameter. 

 Tasmania exports about 40,000 worth of Wattle-bark annually. 

 Messrs. Borrow and Hay croft, in South- Australia, are now pro- 

 ducing a thick fluid extract from Wattle -bark and twigs by steam - 

 machinery, the average percentage of mimosa-tannic acid in this 

 extract being 38.20. By cutting oft' branches in Wattle-plantations 

 the needful thinning out is obtained. Catechu can be realized from 

 the thick tan-liquid by mere exsiccation. In 1880, the United 

 Kingdom paid, according to Mr. P. L. Simmonds, three million 

 pounds for tan-barks, and one and a quarter million for other tan- 

 substances. The wood of this Acacia, particularly when the trees are 

 in an unhealthy state, is sometimes bored by the large larva of a 

 moth, namely that of Eudoxyla Eucalypti, also by beetles of the 

 genus Phoracantha [C. French]. 



For fuller information the "Report on Wattle-bark," presented 

 in 1878 to the Parliament of Victoria by a special commission, may 

 be referred to. 



Acacia moniliformis, Grisebach. 



Argentina. The " Tusca." The young pods are used for feed- 

 ing horses and cattle [Dr. Lorentz], like those of Acacia Cavenia 

 in South-Western America. 



Acacia Nilotica, Delile. 



Arabia, Egypt and Nubia. Closely allied to A. Arabica. Wood 

 very hard. The growth of the tree is comparatively quick ; it 

 succeeds also on sandy and brackish ground [Dr. Schweinfurth] . 



Acacia Osswaldi, F. v. Mueller. 



Widely distributed through the desert-country of Australia. 

 Pasture-animals browse on the foliage [Rev. J. M. Curran]. 



Acacia pendula, Cunningham. 



New South Whales and Queensland, generally in marshy tracts of 

 the interior. The " Boree " or " Weeping Myall." Reaching 35 

 feet in height. Wood violet-scented, hard, close-grained, beauti- 

 fully marked ; used by cabinet-makers and turners, in high repute 

 for tobacco-pipes [W. Hill]. The tree is desirable for cemeteries. 



Acacia penninervis, Sieber. 



Victoria, New South Wales and Queensland. A small tree, so 

 hardy as to occupy sub-alpine localities. The bark contains about 

 18 per cent, of tannin. Mr. A. R. Crawford found the bark of 

 singular tanning strength, and producing a soft and pale leather. 



Acacia Peuce, F. v. Mueller. 



Central Australia. Wood one of the hardest and heaviest in 

 existence; dark-colored. Specific gravity 1.369-1.375 [Blackett].
