IS On Ihe Draught of Plonglis. 



It would be desirable to prosecute these experiments in wet 

 seasons and in more adhesive soils. I have little doubt that I) P 

 will g;enerally be found lighter than Hart's ; in comparing the 

 two ploughs together, it is evidently constructed for lighter 

 draught. 



Having satisfied my own mind about the relative position of 

 the above four ploughs, I was led on to inquire a little into the 

 cause of the difference, and thence to attempt to analyze the 

 draught of ploughs as connected with the swing and wheel prin- 

 ciple ; but, learning that the early publication of the Journal does 

 not admit of my completing my experiments, I will reserve them 

 (if thought sufficiently practical), together with other matter that 

 I have promised in the course of this paper, for a future occasion. 



And believe me, dear Sir, 



Yours faithfully, 



Henry J. Hannam.

HI. — Account of a, Field Thorovgh-dramrd, at Drayton, in 

 Stafford.^hire, By the Right Hon. Sir Robert Peel, Bart., 

 &c.' &c. 



To Ph. Pusey, Esq. 



My dear Sir, — I comply, with the greatest pleasure, with your 

 wish that I should give you the particulars respecting the field 

 which I drained and subsoiled, the produce of which was sent to 

 you by our common friend Dr. Buckland. 



I was riding with him over a part of my estate in the autumn 

 of 1840. He remarked a quantity of manure put upon a field, 

 of poor soil, very wet, and in bad condition generally, and said, 

 the tenant who placed it there went to very needless expense, 

 for that manure would be of no service while the land remained 

 undrained and in the state in which it then was. 



He said also, that the land in Scotland which had been so 

 much improved by Mr. Smith, of Deanston, was naturally no 

 better than that on which we were riding, and that in its original 

 state it resembled that land in respect to the quality and properties 

 of the soil in many particulars. 



These remarks of Dr. Buckland did not pass unheeded. I 

 selected the worst field I could find, and determined strictly to 

 follow the plan of Mr. Smith in respect to it, so far as draining 

 and subsoiling are concerned. I first proposed to the tenant that 

 he should retain the field and do the work under my directions ;
