Dear Sir, 



Agreeably to your request, the bearer brings the 

 four coulter drill plough, the merit of which consists 

 in the simplicity of its construction. The leathern bot- 

 tom of the seed hopper forms the principal superiority 

 of this tool, rendering brushes and complication un- 

 necessary, and yet I have not observed the seed bruis- 

 ed, or the delivery of it either uncertain or irregular. 

 It came to me with a tongue, but finding two horses 

 entirely unnecessary, a pair of old shafts were fixed to 

 it, and one horse, a man, and an active boy, were 

 found sufficient to drill at the rate of six acres per day ; 

 the boy leads the horse, and the man, ivalking behind, 

 observes the delivery from the funnels, lest any thing, 

 accidentally mixed among the seed, should retard or 

 stop the delivery ; and also to clear away from the 

 coulters any rubbish they may gather, when it is like- 

 ly to stop the funnels. This is best done with a light 

 handy pole, sharpened at the point, and an upright 

 thumb left near the point of this pole, and with 

 such an instrument as this, and proper attention, 

 the horse need not stop until the through is per- 

 formed, unless an occasional stump happen to be 

 in the way, and over this the plough is readily lifted. 

 .At the end of each through, the boy turns the horse.
