Some Notes on the" Wattle" or " Acacia"(Continued.)
I have here some statistics for the yearending June 30, 1923.
Wattle bark ex 'ported from Tasmania was 53 1222cwt.,valued at
25,474, of which 16,659 wasfrom Hobart the remainder from
Launceston. Quite lately a shipment wassent direct from Bridport.
12 miles fromScottsdale, to the mainland, the first tobe shipped
direct. There is about 600worth of wattle bark used in this
Statefur tanning purposes every year, which, jnaddition to exports,
it will be seen thatit is very valuable.
Mr. Mitehell, on East Coast, had a plan_tation of black wattle
harvested once illseven years gave the largest percentaged tanning
under cultivation.
The black wattle contains 38 degrees tanning. the silver wattle
24 degrees, approximately.Imports of Wattle Bark Into
