118.— New red sandstone, Mansfield, Notts. Fine- 

 grained micaceous sand, found at Mansfield, and of great 

 value in the production of ornamental castings. Its ex- 

 cellence as a moulding sand arises from the fineness of its 

 grain, its porosity, great purity and smoothness, the latter 

 property contributing to give a high face and finish to the 

 castings made with it. It is exported in considerable quan- 

 tities to the Continent. The following is an analysis of the 

 sand by Mr. Haywood :
