they also affirm that they are good against most diseases of the 

 thorax, and that by the use of them, they are enabled to repel 

 hunger and thirst for a long time. In Breadalbane and Rosshire, 

 they sometimes bruise and steep them in water, and make an 

 agreeable fermented liquor with them. They have a sweet 

 taste, something like the roots of liquorice, and when boiled 

 are well flavoured and nutritive, and in times of scarcity have 

 served as a substitute for bread. Boiled well a fork will pass 

 through the tubers, and dried slightly and roasted they are served 

 up in Holland and Flanders in the manner of chestnuts. The 

 plant is called Wood-pea or Heath-pea in England, and Knap- 

 perts in the lowlands of Scotland. In Gaelic it is called Cor-meille.
