into the wall-plate, and it is made sufficiently wide to 

 allow of five inches projection on the outside, this part 

 is scooped out on the upper side, and becomes the gutter,

 of the rafters, that stay and make the sash bars firm ; venti- 

 lation is obtained by slides in the front wood work, imme- 

 diately beneath the wall plate, and by sashes 2 feet six in- 

 ches long and the same width, fitted by hinges at the 

 ridge pole, these are lifted by a three-eights iron rod, 

 having a hook at the upper end which is slipped through 

 a hole in a small plate affixed to the middle of the lower 

 end of each sash; the rod is steadied by being passed 

 through two apertures at the end of a shaft three inches 

 long that is welded, each into a small plate, and this 

 screwed to the back side of the house; one about nine 

 feet, and the other five feet from the ground. In the front 

 of the lower hole is a screw worm, and 'a thumb screw to 

 fit, which on being turned either way liberates or fastens 

 the bar, and the sash is kept firm at any desired height.
