Of the Coulter.$9 ting this part of the ground, the fur- row is not raiſed at all, nor turned over, but lefc jumbled in confuſion. And, Zafſtiy, this poſition of the coulter and land ſide is very unfit for regula- äng the motion of the plough. When ehe ſoil 1s ploughed deep, this is not ſo diſtin&ly perceived, by reaſon of the looſe earth which tumbles in between the coulter and ſock, and ſerves to fill up the vacancy between the corner of the ſole and the firm ground, But, in ploughing a ſhallow ſoil, it is very evident. The only parts of the plough which pref on the firm ground, are the coulter, and hindermoſt part of the tand ſide; and the ſmalleßt reſiſtance on

the furrow ſide of the coulter is ſuffici-

ent to turn it to the land.
