 the bundles of drying-paper containing them, be- 

 tween two stout boards, which should be larger than 

 the paper by a quarter of an inch each way, of an 

 inch and-a-half in thickness, and each having two 

 bars or batons of two inches in breadth, and five- 

 eighths of an inch in depth, and rabbited, let into
