While examining the work, your committee had some 

 doubt whether the dynamometer indicated truly the ac- 

 tual power in pounds weight applied by the team ; — but 

 a re-examination of the instrument, as to the manner in 

 which it is graduated, by the actual suspension of so ma- 

 ny pounds weight upon it, as well as the assurance of 

 the Editor of the N. E. Farmer, who has much practical 

 experience in these matters, has removed these doubts. 

 Our conclusion is, that the actual power applied to draw 

 a plow in common grass land, varies from three hundred 

 to six hundred pounds, — depending upon the structure of 

 the plow and the skill of the plowman ; and that by 

 proper attention to these considerations, and due care 

 in obtaining plows of the best construction, one half 

 of the labour and expense of plowing may be saved, 

 as compared with the manner in which it is usually 

 done. 



Thus far your Committee found their duty a pleasant 

 one, because they felt they were eliciting valuable infor- 

 mation on a useful subject. But when they came to re- 

 view their minutes, and to attempt to discriminate, 

 where the shades of difference were so very slight, it 

 was no easy task to be assured, which of several should 

 have the preference. 



From the plows made by D. Prouty & Co. we se- 

 lected No. 5, entered by Samuel Jenkins, Jr., and No. 

 6, entered by John F. Carlton.
