EEPOET OF THE SPECIAL COMMITTEE 



ON THE 



SUPPLEMENTARY PLOW TRIALS, 



Held at Brattleboro', June 2, 3 and 4, 1868. 



The Executive Committee of the New York State Ao-ricultiiral 

 Society, having been informed by the report of the judges of the 

 plow trial instituted by the Society at Utica, last year, that, from 

 accidental circumstances, they were unable to complete the trials 

 necessary to ascertain the facts in relation to the plow and its 

 working, which were of great importance to the plow-wright and 

 the farmer, it appointed a special committee, consisting of the 

 chairman of the board of judges and the consulting engineer of 

 the Society, who were requested to complete the trials at such 

 time and place as they might deem most desirable in order to 

 obtain correct results. 



In pursuance of this appointment, they fixed on Brattleboro', 

 Vermont, as the place, and June 2, 1868, as the time for obtaining 

 the supplementary tacts which were necessary to the completion 

 of the plow report. 



The points upon which we endeavored to obtain light were the 

 following: 



I. What is the inbrease of power required for each successive 



inch of depth in plowing ? 

 II. What is the increase of power required for each successive 

 inch of width in plowing ? 



III. What is the increase of power required when the furrow 



slice remains of the same size for each successive 

 increment of velocity ? 



IV. What proportion of the total amount of power consumed 



in plowing is absorbed by the dilferent parts of the 

 plow, viz., the land side, the share, the mould-board? 

 V. What is the influence of the coulter on draught?
