 crops for a time as may not be desired. 



6. Weeds are usually not of much value 

 for food. If weeds were of much value as 

 food either for man or beast, there would 

 not be the same necessity for waging 

 against them a war of extermination, but 

 usually they are of no value. When live 

 stock feed upon them^ it is generally 

 because of short supplies of their proper 

 food, unless it be when the weeds are very 

 young. Nearly all forms of weed life are 

 possessed of acrid or bitter juices which 

 render them distasteful to live stock, and 

 many of them become so woody at a com- 

 paratively early stage of their growth that 

 they are in consequence left undisturbed. 

 Quack grass, it is true, forms an exception, 

 but quack grass is not more valuable than 

 many other kinds of grass, and when we 

 consider the difficulty found in eradicating 

 it, we cannot regard it in any other light 

 than that of a most troublesome weed. The 

 value of weeds for food is so trifling, com- 

 pared with the mischief which arises from 

 their prevalence, that we ought never to 

 sow them or tolerate their presence for such 

 a use.
