* Few of the species yielding good brown dyes are capable also of giving 
red or purple ones. But this colour is a very durable, and, therefore, useful 
one; it is extensively employed among the peasantry in this and other coun- 
tries. The processes for developing it are much more simple; but the lichens 
yielding brown dyes alone have never been articles of commerce. '
