 with a Aiding valve to draw out the corn below, which is poured in 

 at the top ; in three or four places a tin or wooden pipe full of holes 

 is made to pafs horizontally through the box to give air to the corn, 

 the whole of which, when any of it is drawn out below, is moved

 of the horizontal tubes. 



The moft fecure way of preferving a great quantity of wheat, ac-
