A storehouse for grain. The construction of this class of buildings has not, we believe, received that attention from the scientific which the importance of it deserves. The best which we have met with in print consists of a plain rectangular building, about twice the height of the distance between the opposite walls, that is 20 feet high by 10 feet in width on each side, and provided with numerous air-holes, declining outwards, to prevent the entrance of rain or snow; from each air-hole to a corresponding one on the opposite side is fixed an inverted angular spout or gutter, which permits the air to pass through unimpeded by the corn lying above it. As many of these gutters are fixed, as there are holes to receive the ends after crossing the building; and the extremities of the holes are covered with wire gauze, to defend them from vermin. The first floor of the granary is divided into a series of hoppers, that empty themselves into one large hopper underneath, provided with a sliding door to regulate the passage of the grain into a sack or other receptacle.

At the top of the building is a loft, to which the corn is first hoisted by a tackle or crane, and is discharged over a cross bar into the body of the building, which may be continued until it is filled to the top.

Upon drawing off any corn at the bottom, the whole of it is put into motion, and the airing of every part is promoted; the process of airing is however continually going forward through the numerous passages under the inverted gutters, the angles of which, it is said, do not fill up by the lateral pressure of the grain.
