100 NOTES. 



Corylus Avellana, or Common Hazel, is also in this class. In 

 countries where yeast is scarce, the twigs of Hazel, twisted toge- 

 ther, so as to be full of chinks, and steeped in ale during its 

 fermentation, then hung up to dry, may be put into wort instead 

 of yeast, It is a practice in Italy, to put the chips of Hazel into 

 turbid wine to clear it, which it does in twenty-four hours. 



Withering's Bot. 



In the Class ^lono-cia, is found the Urtica or Nettle ; the 

 stalks of which may be dressed like flax, or hemp, for making- 

 cloth, and paper. In Kamtschatka, they use no other material in 

 the manufacturing of cordage, sail cloth, and linen ; and consider 

 these fabrics, when produced from nettles, as superior, in every 

 respect, to those made of hemp and flax. 



As to the difliculty ofliandling the nettle, read Aaron Hill's 

 advice. 



Tender hearted, stroke a nettle, 



'Twill sting you for your pains ; 

 Seize it, like a lad of mettle. 



It soft as silk remains.

 The Calla. 



Class Gynandr. Calla .Ethiopica. 



Another species is found in the marshes of Sweden, the flow- 

 ers of which are sometimes almost as beautiful as those of the 

 green-house plant, but being short, it has a less graceful appearance.
