WATTLES AND WATTLE-BARKS. 37 



of Brisbane, who obtained it from Eiioggera. It was from trees 15 feet in 

 height and G inches in diameter, was collected in May and analysed in July. 

 It gave 18'24 per cent, of tannic acid and 35 95 of extract; but the bark is 

 too thin, and it gives too dark coloured a liquor for it to be looked upon 

 very favourably. 



In an official report for the Melbourne Intercolonial Exhibition of I860, 

 Baron Mueller incidentally mentioned that a sample of this bark contained 

 17'9 per cent, of tannic acid, not a result sufficient to excite any great ex- 

 pectations. 



As regards the occurrence of the mountain hickory in Victoria, Baron 

 Mueller speaks of it as scattered through the eastern half of the Colony, 

 over ridges and ranges, gregarious on some of the sub-alpine declivities and 

 plateaux. He speaks of it (1885) as " a usually small tree," but subsequent 

 exploration towards the New South Wales border may cause this to be 

 modified. 



It is found also in Tasmania, but apparently only on Mount Wellington. 

 It has a wide range, as it extends to Southern Queensland, but New South 

 AVales seems to be the natural home of the tree. In our Colony it extends 

 from South to North, in the eastern half, on the southern ranges, the 

 Dividing liange and its spurs, and the New England district. 



While this species is so abundant, and so extensively distributed, it would 

 appear that only bark from Southern New South Wales is of any great com- 

 mercial value, and I therefore give particulars of such localities in a little 

 more detail. 



It is found from the Clyde and Bateman's Bay district, all along the coast 

 land, right down south to the boundary of Victoria. On the eastern moun- 

 tain slope and ranges it attains a good height (20 feet to 40 feet), with a 

 diameter up to 18 inches. Trees a foot in diameter are common. It is 

 found a good size along the strip of forest land fringing the plains of the 

 Monaro. The largest trees appear to occur in the mountain ranges near 

 Delegate, which form the southern boundary of the Monaro, where for 

 instance, near Brown's Camp (the locality from which I first obtained the 

 samples which enabled me to draw attention to the extraordinary value 

 of this bark), the trees attain a height of from 40 feet to 80 feet, and a 

 diameter up to 2| feet, while trees of a diameter of 18 inches to 21 inches, 

 are not scarce in the locality. 



Nelligen, Moruya, Araluen, Tilba, Cobargo, Colombo, Bega, Candelo, 

 Bombala, Delegate, and the Twofold Bay district are good localities.
