them, but that of fulphur ; and that gives a bad fmell to the 

 corn. 



In Tv^ay 175 1, we put feme weevils into one of our granarir : 

 and when it was opened in Auguffc 1752, we found none. 



M. Duhamel, in the fifth volume of his Treatife on Agricul- 

 ture, gives the following farther experiments on the prefervation of 



corn. 



Experiments made at Denainvilliers, on the prefervation of corn.. 



'T^HE wheat of 1754, being of an excellent quality, and that 

 -'■ harveft having been very fine and dry, my corn, after being 

 kept all the winter in a common granaiy, was divided into two 

 parts, one of which was depofited in one of our granaries of pre- 

 servation, without being ftove-dried ; concluding that, as it was fo 

 well conditioned, the renewing of the air with the bellows, would 

 be fufficient to preferve it. In eft'edt, this corn remained always 

 cool and in good order. 



The other part was ftove-dried and laid up in another granary of 

 prefervation ; where, as it did not heat at all, I am apt to think it 

 would have kept without the afliftance of the bellows : but this, 

 is only a conjciSure ; for it was ventilated nearly as much as the 

 other. 



In my treatife on the prefervation of corn, I mentioned my having; 

 kept wheat feven years, without its being attacked by any infeft r 

 but indeed it had not weevils in it, when it was put into the gra- 

 nary, which was always kept fo clofely lliut, that there was not the 

 lealt room for that infedt to get in any whete.- -I likewife faid in 

 the fame work, that after having laid up in a granary of prefei^va- 

 tion, wheat which had been ftove-dried, and put fome weevils in-. 

 ;imong it, not one of them was to be found when that granary was 

 emptied eighteen months or two years after. 



The cafe was not the fame this year. I had put fome weevils- 

 into the granary in which I laid up wheat, not ftove-dried, of the 

 harveft of 1754. 



In May 1756, wanting to lay this wheat, which had not been 

 flove-dried, upon fome other which had been dried, in order to empty 

 ')ne of my granaries for wheat of the harveft of 1755, I ordered it 

 to be fifted through a wire fcreen, and found, while that was doing], 

 nearly the fame quantity of weevils that I had put into it. I
