WATTLE CULTIVATION. 



77 



In Australia a full-sized tree will give about 100 lb. of bark, at 

 about seven years old, while we may reckon upon half that amount 

 in the fourth year. Generally speaking, Wattles require a cool district, 

 and will no^ give such good results near the coast. I noticed some very 

 fine Black Wattle trees in South Queensland, but was told that although 

 they grew so large they were not of much commercial value, ten per 

 cent, of tannic acid being the average yield for a matured tree, which 

 goes to show that although the tree may grow well and appear all that 

 is desired in many kinds of land and climates, we have to prove by 

 actual results the most suitable soils and situations to render it a good 

 commercial undertaking for tanning purposes.
