491. When beginners are learning to harrow, I always walk 

 with them, and tell them to keep their eye on the fore feet of the 

 animal that is nearest the harrowed ground, and keep him just 

 so far from it. If he keeps his eye on the harrow most of the 

 time, he will be very liable to have his team on the harrowed 

 ground, or too far away from it. Always allow the harrow to 

 run one or two teeth on the harrowed ground, so as not to make 

 balks. One can harrow faster to go directly back and forth than 

 he can to go round a land. Always harrow the borders of the 

 field thoroughly. I seldom harrow a field but twice, once be 

 fore and once after sowing, after which the ground is rolled.
