14 American Ploughs. Mangel Wertzel. 



our second volume, pages 144, 5. I send also an ex- 

 tract from Evans and Ruffy's Farmer's Journal ; giving 

 an account of one of the trials of two of Mr. Barclay's 

 American ploughs; very favourable to those Implements. 

 The three horsed plough is an excellent instrument ; but 

 great injustice has been done to it, by its being worked 

 only with two horses abreast, or four oxen. The three 

 horses abreast, are essential to its movement, because it 

 is calculated for the third horse, on the off side, to keep it 

 to its work ; and the power of the whole is equally di- 

 vided, and correctly balanced. As to the objection that 

 the plough (if this be the one meant) will not clear itself 

 in foul ground, and is not calculated for heavy and stiff 

 soils, or stony ground, nothing can be more unfounded, 

 as they will find on executing the directions I have trans- 

 mitted. Detach the coulter, and it will turn in Buck- 

 wheat, clover, stubble, and any foul cover of weeds, or 

 grass, to the greatest perfection : I think quite as well 

 as Ducket's skim coulter plough. There is no ground, 

 capable of aration, too heavy or stiff to resist the power, 

 or perfect operation of this plough. 



I send some seed of the orange coloured Mangel 

 Wurtzel, which, being highly esteemed in Europe, I 

 wish some of our members would carefully cultivate, to 

 assist me in obtaining seed for distribution, and also to 

 spread the knowledge of this excellent root ; which has 

 obtained in Europe, and in England particularly, (from 

 whence it was sent to me by Mr. Barclay) a celebrity 

 beyond any other, as food for cattle. The mode of cul- 

 ture will be seen in our 3d volume. Mr. Barclay in- 

 forms me, that the orange coloured root grows more 

 'inder the surface, than the mottled or white kinds ; but
