vi PREFACE. 



tent that this object shall be attained, will 

 these labors be rewarded. 



It is not the design of this publication to 

 disparage any one ; on the contrary, it is de- 

 sired to give ample credit to all who contrib- 

 uted to the solution of the plow problem. If 

 only brief mention is made of others, it is be- 

 cause they really deserved but little credit, or 

 their merits are forever buried in obscurity. 

 It is proposed to set forth without exaggeration, 

 the claims of the supreme inventor in this 

 line to the grateful remembrance of the pub- 

 lic. And by the public is meant not only the 

 American people, but all who are fed from the 

 ample granaries of this country, or share the 

 benefits of the improved tillage, whether on 

 this continent or in Europe, made possible 

 and actual by the inventive genius of Jethro 

 Wood.
