Report on Trials of Plows. 



Tenth — Even distribution of wear: The difference in this 

 respect was very slight, but while every part of Holbrook's 

 mould-board was evenly polished, there were a few points in 

 Collins' which had evidently less rubbed. Slight as the difference 

 was, there was a difference, and we were therefere compelled to 

 decide this point in Holbrook's favor. 



Eleventh — Eegularity or trueness of turning: Decided in favor 

 of Holbrook's. 



SUMMARY. 



The first, second, third, fourth, sixth, ninth, tenth and eleventh 

 points, eight points in all, were decided in favor of Holbrook's 

 plow. The fifth and eighth points were decided in favor of Col-

The judges therefore decided that Holbrook's plow was the 

 best one, and as it fully met the requisitions of the Society, they 

 adjudged to it the Large Gold Medai.. 



The annexed cut. Fig. 114, gives a tolerably clear idea of the 

 appearance of Holbrook's prize plow No. 69. 



It will be observed that it enters the ground with a very low 

 inclined plane, rises by an easy curve which elevates the slice 

 into the air, and then by a succession of sharp twists in different 

 directions it cracks the slice, and if it is in a tolerably dry condi- 

 tion reduces it to powder. 



The Society called for a plow " which will raise the lowest soil 

 to the surface of the furrow." This was done by this plow at 

 Utica to the very letter of the requirement, but as we desire that 

 the public may exactly understand the whole case, we must state 

 that owing to the extreme dryness of the soil and its minute pul- 

 verization, the lowest soil, after Ijeing lifted to the top of the
