20 
WATTLES AND WATTLE-BARKS. 
A second sample forwarded to me April, 1890, and analysed the same 
month, is from the vicinity of Mount Torrens, 20 miles east of Adelaide, and 
was obtained from Mr. J. E. Brown, Conservator of South Australian 
Eorests, through the courtesy of Mr. Albert Molineux, Secretary of the 
Agricultural Bureau of that Colony. It yielded 391 per cent, of tannic 
acid, with 73*5 per cent, of extract. It is of course an admirable bark, but 
it is thinner than the preceding sample, and would at once strike an expert, 
even from visual examination, as second to it. But even this contains 
nearly 3 per cent, of tannic acid more than any other sample of wattle-bark 
of other species I have examined. It is, however, only fair to say that I 
have been unable to procure samples of the best brands of Tasmanian bark. 
In forwarding the sample, Mr. Molineux says, — “ The hark was taken 
from a height of about 2 feet above ground. It was from a large tree, of 
which there have been, and still are, great numbers in the locality. Mount 
Torrens District is the best in the Colony for rich good bark, and the 
Conservator has in hand upwards of 30 tons of seed from these, some of 
which is for sale.” 
One pound of plump South Australian seed of this wattle contains, 
according to a careful determination under my own supervision, 23,808 
seeds, so that cultivators may reckon safely on 20,000. 
The following are results of analyses of thirteen samples of A. yycnaniha 
bark received from Mr. J. E. Brown. They were stripped 29th April, 1890, 
analysed a month later, and were grown on the Government Earm, Belair, 
S.A. Height of trees, from 8 to 14 feet.
