to twenty-fix feet ; by which means the heavier 

 particles fly fartheft, and the unfoiind corn and 

 hufks are of coijrfe left in the intermediate fpace; 

 as this part of the procefs occupies as little, if not 

 lefs time than any other, it will not be difficult to 

 find a fufficicnt time of fine weather in any feafon, 

 to place a fail-cloth, or boards prepared for that 

 purpofc, to the diftance of twelve or fourteen kct 

 from the doors, which will then efFcftually anfvver 

 every purpofe of thofe now -in ufe.* 



The following are the dimenfions of a barn 50" 

 feet by 20 1 feet, and thofe of the model. 



Dimtnjions of the Model. DimenfienS of a common Barn. 



1472 fquare feet the area. 1475 fquare feet the area. 



30,900 cubic feet for corn only. 24,426 cubic feet for corn only. 



445 cubic feet of timber. 702 cubic feet of timber. 



By which calculations it appears, that a barn built 

 on the prefent model gains, on one in common ufe 

 of the fame area, 6474 cubic feet of fpace, and is 

 built with 257 cubic feet of timber Icfs; and as 

 there is nothing in its confl-rudion which would 

 increafc the expence of workmanlliip, the dif- 

 ference between the expence of building a barn on 



• As threfhing is for the moft part done in tb'' winter mnnths, wV.en 

 tlie barn doors are generally frequented by cattle, poultrj', and birds, 

 great inconvenience would be found in lergtlieninp the floor by a fail- 

 cloth or boards, as Mr. Dobfon pro;iofcs. But if the corn be drefled 

 with a winnowing engine (as is frequently pra^ifed in many counties) 

 the length of the floor will be quite fufficicnt. In every other refpeft 

 we think this the completeft model for a barn wc have ever feen.
