IN former days, when so much was done by hand that is now 

 ' done by machinery, the thistle called the Teazle (Dipsaciis 

 futtonum) was of great value in British commerce, being used 

 by countless thousands in the manufacture of broadcloth. 



When the woollen threads are woven so as to form the fabric 

 of the cloth, there is no nap upon them, this having to be pro- 

 duced by a subsequent process. The plan of former days was, 

 to procure a quantity of the seed-vessels of the Teazle, and dry 

 them. Ttey were then fastened to an instrument something 

 like a wooden battledore, and swept over the surface of the cloth. 

 By degrees the delicate booklets which terminate the many 

 scales of the seed-vessel tore up the fibres of the cloth, and pro-

 thread. When this nap is worn off, the threads are again 

 visible, producing the effect called " threadbare."

 Teazles increased in due proportion, and vast quantities were
