 Methods of cutting off the steam, and working it in an

 and locomotives all came .under his improving hand, with

 the cause of much greater strength. 



His greatest invention has been considered to be the

 air which was passed through at regular intervals. 



He constructed the blockade runner * Flora ' and other
