we take this opportunity of acquainting them, that the kiln may 

 be fubftituted in their place, and with nearly equal advantage ; 

 afpecially where the quantity to be dried is not very great : and iu 

 reo-ard to publick granaries, we recommend to the perulal of the 

 curious, as well worthy their attention, an ingenious performance * 

 lately written on that lubjeift, by a lady of our own country. 



The editors of Mr. Lifle's hufbandry having given a concife 

 abridgment of the experiments in M. Duhamel's treatife on the 

 prefervation of corn, we fliall copy from them what is mofl elfen- 

 tial therein, and then add the farther experiments mentioned by 

 that gentleman in his treatife on agriculture. 



M. Duhamel caufed a cafe or little granary to be made, of oak 

 plank two Inches thick, forming a cube of five feet every way. At 

 fix inches from the bottom, he made a flooring, or fecond bottom, 

 of lattice work, placed upon joills of five inches thick, covering it 

 with a ftrong canvas : and this little granary was filled quite full of 

 good wheat. It contained ninety-four cubic feet, weighing five 

 thoufand and forty pounds. 



This granary, being filled quite full of corn, is to be covered with 

 good oak planks, fo clofely joined, that neither rats, mice, or even 

 die fmallell infe£l can get in ; leaving only forae vent-holes, with 

 trap-doors, or covers fitted very exadly to them, which will be 

 fpoken of hereafter. 



By this means the corn is depofited in a- fmall compafs, and 

 perfeftly fecured from rats,, mice, birds, and even infe(fls, provided 

 there were none before In the granary, or among the corn : but if 

 there fliould, the means hereafter pointed out will deftroy them. 



It is well known that, in this climate, corn laid up in great heaps 

 will foon ferment and fpoil : to prevent which, it Is necefl'ary to 

 force out the tainted' air, and fupply its place, from tlithe to time, 

 with frefli : in ihort, to eftablifh a current of, air, which ihall pafs 

 through the corn, and carry off^ the dampnefs. To this end, M. 

 Duhamel made a falfe bottom of lattice work, covered with coarfe 

 canvas, (but if it were for a large, granary, wire, in the manner of 

 a-fieve, might do better,) through which the air could pafs, and be 

 forced out at the vent holes at top. 



This purpofe is anfwered by bellows, and the mofi proper for. 

 this end are thofe contrived by dodor Hales, they being conltruded
