Report on Trials of Plows. 



more durable. It is difficult to describe the mould-board, which 

 is of uo regular figure. It approximates in its general outline to 

 a cone, but has been pared away at different points to suit the 

 views of the maker, and to adapt it to what he conceives to be 

 the wants of the farmer. 



The distance across, from the land side to the point of the 

 feather, is 10| inches. The length from the point of the plow to 

 the point of the feather is 14 inches. Length of the land side, 

 23 i inches. From the point to the standard is 15 inches. 



It worked very easily, and was very strongly made, and was of 

 durable materials. Its great defect was a want of pulverizing 

 power; the earth was hard after being plowed. 



The judges decided as follows between these two plows: 



First. Pulverizing power: Very greatly in favor of Holbrook's. 



Second. Non-liability to choke in stubble: Equal in this respect. 



Third. Lightness of draft. 



At a subsequent trial of their draft, side by side, in soil as 

 nearly alike as possible, Holbrook's average draft was 502 pound 

 yards. Burch's average draft was 432 pounds. In the first case, 

 Buch's was lightest by 95 pounds, or 15.7 per cent. In the second 

 case he was lighter by 70 pounds, or 13.9 per cent. The merit of 

 lightness of draft was therefore awarded to Burch. 



Fourth — Ease of holding: Decided in favor of Burch. 



Fifth — Dura'bility: Both equal in this respect. 



Sixth — Cheapness: In favor of Burch. 



Seventh — Excellence of mechanical work: In favor of Hol- 

 brook. 



Eighth — Excellence of material: Both equal in this respect. 



Ninth — Thorough inversion and burial of weeds: Holbrook. 



Tenth — Even distribution of wear: Holbrook, slightly. 



^^ewn//<'— Regularity or truoncss of turning: Holbrook.
