On the Rachheath Sub-Turf Plough. 



I have had it made as pkiin and as clear as I possibly could : I 

 trust therefore that there will be no difficulty attending the mak- 

 ing of other ploughs from it, if required. From the above sketch 

 of the Sub-Turf Plough it will easily be seen that it differs but 

 little from the plough commonly in use in this county. The chief 

 difference consists in the share having two wings instead of one 

 wing, and in the absence of the mould-board or breast. Very little 

 have I to add respecting the method of using, or the advantages 

 derived from the use of the plough to those which I stated in 

 my letter to the Royal Agricultural Society (see Third Part of 

 the Journal, p. 256), excepting that after an experience of nearly 

 two years it has fully answered my expectations ; and I can give 

 no better proofs of its merits than by the extensive adoption of it 

 by my neighbours, in subsoiling their meadows and pastures ; 

 and so perfectly satisfied am I with the results arising from the 

 use of the plough, that I have despatched one of the ploughs to 

 subturf some meadow and marsh lands about tvv^elve miles from 

 this place ; and hope to have about 120 acres subturfed between 

 this time and the ensuing spring. 



I send you also tw^o sketches ; one of an implement which I 

 call the Pig's Head (from its shape being similar to the head of 



18 inches.

that animal), for the purpose, when attached to the plough, of 

 throwing potatoes out of the ground, instead of forking ; and 

 when attached to the plough for that purpose, the coulter must, 

 in the first place, be removed : and the plough with the coulter
