The foliage is the only part of this tree which promises to be of any 
utility ; when dry, it affords, by decoction, a beautiful yellow color, which 
is rendered permanent by the addition of a little alum and is used to dye 
wool and cotton. But if these leaves had possessed any considerable value, 
they would doubtless have found their way into commerce. The first ob- 
stacle to their use is the expense, in a country where labor is dear, of col- 
lecting them in sufficient quantities. Of this I can judge from the difficulty 
I experienced in gathering a few pounds.
