On Smut in Wheat. 61

 where hot lime had been used, no smut prevailed, but 

 that the crop was much hurt where cold lime had been 

 substituted. 



" Some caution is certainly necessary with regard to 

 lime ; for should it be used when not properly slacked, 

 the great degree of heat thereby occasioned, would de- 

 stroy the vegetative principle of the seed; but if appli- 

 ed with the precautions recommended, I am persuaded 

 that the liming and pickling may, in some slight degree

 his applying the lime without slacking it sufficiently." 



The authority upon which the above observations 

 and facts are given, is certainly lessened from the cir- 

 cumstance of its being anonymous ; and yet they are 

 in part corroborated by so many living persons, that we 

 suffer no risque in admitting them in favour of the prac- 

 tice under consideration. It must however be remark-

 being the chief agent in the prevention of the disease, 

 is certainly not supported by as many, as that which 

 attributes an equal share to the salt water.* I myself was

 lime is useful only to dry up the superfluous moisture and 

 make the grains separate and sow more readily ; chalk or
