666 SPERGULA. [CLASS X. ORDKK IV. 



but in Holland, Germany, France, &c. it is often sown with the corn, 

 for the purpose of affording a supply of food to sheep and cattle when 

 turned into the stubble, and it is said to improve the flavour of the 

 mutton, and makes a richer milk and iiner flavoured butter. The 

 seeds, as well as the whole plant, are a very favourite food of fowls, and 

 are thought to cause them to lay a greater number of eggs, and to 

 improve the flavour. It does not, however, appear that Spurrey 

 could be cultivated with us with any great advantage, except as it 

 appears to be a very nutritive plant, grows quickly, and flourishes well 

 on poor sandy soil ; it might with some advantage be encouraged on 

 waste lands. In Norfolk it is caWed pick-purse, and in Scotland it is 

 commonly known by the name of yarr.
