 The inventor of these improvements has also constructed

 proved plan, which are intended to be of cast iron, and 

 which, by diminishing resistance, will render them, when 

 of small size, easy to be worked by two middle sized 

 mules or horses, in cultivating corn or seeding wheat. 

 With this force, a gentleman of Maryland has used these 

 ploughs, of the size now exhibited, in working corn and 

 seeding wheat. The rows of his corn are four and a half 

 feet apart. With his double furrow plough, drawn by 

 two middling sized mules, he works his corn completely,
