284 Report of the Special Cojlmittee. 



VIII. What is the influence of the wheel on draught ? 



We are ashamed to be obliged to state that we quite overlooked 

 this part of our programme, and are therefore unable to give an 

 experimental answer to this question. 



IX. What is the influence of the plowman on draught ? 



We have already answered this question incidentally in the 

 earlier portions of this report. In some cases, where he was 

 obliged to exert his force through a lever to counteract a tendency 

 to irregularity, in consequence of a maladjustment of the parts, 

 the extra power required rose up to 115 pounds. In all cases the 

 lightest draught was shown where the plow ran with the least 

 interference on the part of the plowman. 



We cannot close our report of these trials without the expres- 

 sion of our sincere thanks to Gov. Holbrook and Mr. Joel Nourse 

 for the very valuable assistance which they rendered to us, without 

 which our labors would have been much less fruitful.
