Copper and Manganese. — In the hill about a mile north of 

 Stapleford, in Nottinghamshire, consisting of Gravel Rock, 

 very similar to that of v\hrch Alderley-Edge NVV of Mac- 

 clesfield in Cheshire is composed, hut not resting on and 

 surrounded by Red Marl as that Hill does, but on and by 

 Coal-measures, a vein of Ore of Manganese, Iron, and 

 Copper, with much Mica, was lately discovered, on the 

 Estate of Admiral Sir John Borlase Warren, Bart., who has 

 caused some of the Ore to be smelted nnd the copper re- 

 fined, vv!)ich proves to be of the very best quality. Sir 

 John had a Coal-seam seven feet thick latclv in work, about 

 SOO yards S of this mine, and has proved the same Coal- 

 measures at about 4 or 500 yards N, while Lord Middle- 

 ton's large Collieries in Trowel are not more than 800 

 yards distant, in the same direction.
