the drill system, and an extended growth of turnips on the ridge 

 as then practised in Northumberland, as well as the use of bones 

 as manure, about the year 1800. Although the bones were round 

 and broken only by the hammer, the advantage of using them 

 soon became apparent ; and the writer s father was the first to 

 follow the example. Their use soon became general on the 

 limestone ; and guano, or any other kind of artificial manure, has 

 not removed them from their high position. 



The subjoined analysis of the soil and rock of the magnesian 

 lime has been made by Mr. James Haywood, Professional 

 Chemist, Sheffield, and shows a great deficiency of phosphates ; 

 hence the application of bones is attended with such favourable 

 results.

The county boundary which separates Derbyshire from Notting- 

 hamshire on the east intersects the edge of the magnesian lime- 

 stone near Hardwick Hall, which stands — with the villages of 

 Rowthorne, Glapwell, Palterton, Bolsover, Oscroft, and Barlbo- 

 rough — on a high and level ridge 600 feet above the sea, and 

 overlooks the coal series. The surface then becomes slightly 

 undulating, and the soil, varying in depth, occasionally presents 

 a crag to the ploughshaire. The Acts of Parliament lor the en- 

 closure of the waste lands were obtained in the early part of last 

 century, and Elmton Common only remained to be enclosed in
