206 Report on Trials of Plows. 



so that the depth shall bear the greatest proportion to the width, will have the 

 preference. The furrow will be laid as nearly as possible at an angle of forty-five 

 degrees. 



§ 7. The judges will be subdivided into committees, as follows. 



(a) A Dynamometer Committee. 



(i) A Description Committee. 



(c) A Weight and Price Committee. 



(d) A Time Committee. 



(e) A Committee on Quality, Material and Mechanical Structure. 



Each judge will form an opinion upon each point of the work of the plows and 

 record it in his note book. 



§ 8. The point of each plow will be detached before it begins to work and accu- 

 rately weighed by the Weight and Price Committee. It will be weighed again as 

 soon as its work is finished. It will be deemed a point of great merit in the plow 

 that shows the least abrasion. 



§ 9. Not more than four plows shall be at work at any one time, and one judge 

 shall be assigned by the chairman to each plow. It shall be the duty of the judge 

 so assigned to observe the action and work of the plow during the whole time that 

 it is in operation. He will note the exact time occupied in plowing. If there are 

 any stoppages he will note the exact time of the stoppage, and state exactly the 

 cause of it. He will measure and record the length and breadth o each urrow 

 slice three times on each furrow, the average of these to be taken as its true size. 



§ 10. The dynamometer will be applied on two furrows, viz., going and return- 

 ing on each lot. The length and depth of the furrow slice shall be measured six 

 times on each furrow, when the dynamometer is applied. The judge in charge 

 will also observe whether the sole of the plow is kept in a horizontal position ; if 

 it departs fi-om this at any time it is to be noted; the instrument No. 2 will enable 

 him to measure the amount of departure. 



§ 11. In addition to the dynamometer trials on the respective lots, additional 

 trials shall be made under the dh'ection of the judges in some level field. Each 

 plow shall plow one furrow without, and the next with the dynamometer attached, 

 and so on until all have been tried. If desired, the judges may then try the 

 draught by a windlass and hand power. 



§ 12. After all of the plowing is finished, the judges will carefully and critically 

 examine each lot. They will designate the different qualities of plowing by the 

 numbers one up to ten. Ten indicates the best plowing, one the worst, and the 

 other numbers the intervening degrees of merit. As the examination proceeds 

 each judge will place in the book opposite to the number of the lot the number 

 which, in his judgment, indicates the excellence of the plowing. The judges will 

 then assemble privately, when the chairman will inquire of each judge successively 

 what number indicating excellence he has affixed to No. 1. The chairman will 

 lecord such numbers opposite to No. 1. He will then ask for the marks of each 

 judge for lot No. 2, and so on until the merit marks of all the judges are ascer- 

 tained and recorded. The plow used on the lot to which a majority of the judges 

 assign the highest marks of merit shall have the preference for " excellence of 

 work." 



§ 13. The records of the dynamometer trials shall then be examined by the 

 judges, and if they find that there is any very striking discrepancy between the 

 different kinds of trial above mentioned they may cause the plows in which such 

 discrepancy exists to be tried over until they arc fully satisfied with respect to
