-iiiife 1^ bupposeu lo ne tne uarnei ot tne ancients, mentioned as hurtful to crops of Wheat 

 It has lived under the opprobrious name of weed, nearly two thousand years. It appears, from 

 the trials that have been made of it here, to be incapable of outliving winter frosts; even in mild 

 winters I never could preserve a single plant under ordinary circumstances. It is never, accord- 

 ing to my experience or information, found beyond the precincts of tillage-fields. It is proba- 

 ble, therefore, that it owes its preservation or continuance in this country to the sprin<v-sown 

 annual crops of grain. It is reasonable to conclude from this circumstance, that it was not origi- 

 nally a native of this country, but may have been mixed with the grain imported from warmer 

 climates. * 



The above statements shew the produce of one acre for one year. Being strictly an annual 

 plant, it may be easily kept under, or totally extirpated, by the practice of the drill mode of 

 husbandry. Indeed it is never found in arable lands that are managed under this superior sys- 

 tem of tillage, except when introduced by having seed from other farms where broad-cast sow- 

 ing is practised. 



Flowers in the first week of July, and the seed'is ripe about the beginning of August. Th 

 seeds vegetate quickly after being sown.
