The reason I have quoted the above is 

 because all over this farm and one or two 

 adjoining farms, ironstone crops out on every 

 ridge. I have been over this farm with Mr. 

 Rogers, and you can see the disintegration of 

 the ironstone going on, so that the soil on 

 these two or three farms, and consequently the 

 grasses, must be rich in iron ; but the benefit 

 cannot extend far, as, the country being all 

 hills, the area is confined by rivulets. 



Mr. Rogers told me that in the eighties, when 

 sheep died by thousands in all the adjoining 

 country, the sheep on these particular farms 

 remained free of disease. 



These facts are to some extent confirmed in 

 England by Dr. Somerville, then Professor 

 of Agriculture at Cambridge University, who 

 experimented with various manures on pasture
