270 [Assembly 



county in this state, made cast plows as early as 1790, and patented 

 the invention in 1797. The patent, which I have seen, was signed 

 by the elder John Adams. The casting of this plow went up through 

 the beam like that of J. Wood's. Mr. Peter T. Curtenius of this 

 city had cast iron plows for sale in 1800. They were of three 

 pieces, raouldboard, landside and share. 



In 1814 Mr. Wood obtained a patent, again in 1819, and by spe- 

 cial act of Congress, procured a renewal of 14 years, making thirty- 

 three years in all. He now seeks another renewal !
