some ; and thus the farmer will be free from all uneasiness 

 on this subject, and from every well founded reproach. 



Observation by the Translator. 



The climate in France being so much warmer than ours, 

 is the reason the author mentions ovens for the purpose of 

 drying wheat : in close and moist weather, after washing, 

 the sun and air being in general sufficient to prepare v.heat 

 for grinding, kilns are not in use as with us, where all 

 grain, unless kept a considerable time on the straw, requires 

 that process to make it icork; nor will it keep in any con- 

 siderable quantity unless kiln-dried, and even in that state 

 if requires constant turning: therefore to millers, who al- 

 ways dry their wheat, and who of course are near to water, 

 the operation of washing seems peculiarly adapted in sea- 

 sons when the smut is common. 



The author does not seem to he acquainted with lashing 

 of wheat to free it from the straw : when this operation i"s 

 performed, the smut balls are not broken as they are by the 

 flail, and consequently less of the black powder adheres to 

 the grain ; and the balls, being lighter than the wheat, may 

 be separated by repeated and careful winnowing. But the 

 second quality, which is obtained by threshino;, after lash- 

 ing, and amongst which the smut balls are broken, ought 

 certainly to be washed.
