58 WATTLES AND^ WATTLE-BARES. 



I now proceed to give brief descriptions, with analyses, of illustrative 

 samples of this bark, and for practical convenience I divide those of New 

 South Wales into southern and northern localities, taking the Hawkesbury 

 River as a natural boundary. 



Souiliern Barks. 



A sample of a smooth green bark from a young tree afforded 33'5 per 

 cent, of tannic acid, and 61'85 per cent, of extract; while a second sumple, 

 from an older tree, gave 35'3 per cent, of tannic acid, and 59'05 per cent. 

 of extract. Both were grown near Penritb, New South Wales. 



A black bark, slightly rugged, from Mulgoa, Penrith, gave 35*56 per cent, 

 of tannic acid, and 59'2 per cent of extract. It was known locally as "Green 

 Wattle." 



A sample received May, 1890, and analysed the following month, was 

 found to contain 34 '85 per cent, of tannic acid and 61 '5 of extract. It came 

 from Burragorang. It is thicker than most barks of this species, and is 

 beginning to be scaly on the outside. Were it not for that defect it would be 

 a splendid bark. It was allowed to remain a year too long on the tree, a 

 fault not usually to be found with bark getters. 



Another sample taken from a tree between 40 and 50 feet high and 15 

 inches in diameter, at a place 12 miles from Burragorang Mountain, where 

 this species was growing in very large quantities, was analysed July, 1890, 

 and found to contain 34*4 per cent, of tannic acid, and 69'33 per cent, of 

 extract. This is a perfect specimen of bark of this species, being of good 

 thickness, smooth, and of good colour. 



A sample from Cainbewarra, from trees 20 to 30 feet in height, and 6 to 

 8 inches in diameter, gathered in August, 1886, was found to contain 32*08 

 per cent, of tannic acid, and 52'16 per cent, of extract. (Proc. R.S., N.S.W, 

 1887, p. 33). A bark grown in the same neighbourhood, and analysed in 

 April, 1890, gave only 24'13 per cent, of tannic acid, and 47'1 per cent, of 

 extract. It is a smooth bark, but from a young tree, being only of an inch 

 thick, and rather fibrous. Had been allowed to remain on the tree a couple 

 of years longer, I feel sure that the percentage of tannic acid would have 

 much increased. 



A sample from Nerriga (on the high table-land from Nowra to Braid- 

 wood), gave the excellent result of 38'3 per cent, of tannic acid, with 62'54 

 per cent, of extract. (Proc. R.S., N.S.W., 1888, p. 271). Height of tree, 

 15 to 20 feet; diameter, 8 to 12 inches. It was stripped in January, and
