AMONG the later memoirs of the Geological Survey of Great Britain, for which Mr. T. Fisher Unwin is wholesale agent, is that accompanying Sheet 142 of the 1-inch map, on “The Geology of the Melton Mowbray District and South-east Nottinghamshire,” by Messrs. Lamplugh, Gibson, Wedd, Sherlock, and Smith (price 2s. 3d.). The map (price 1s. 6d.) is a good one for showing the irregular distribution of boulder-clay across the ridge of Middle Lias, and its cessation in the Vale of Belvoir. Rhætic beds are recognised above the “tea-green marls” of the Keuper in the north and west. In the memoir it is pointed out that the Vale of Belvoir must have lain in the glaciated region, but was an area of stripping rather than of accumulation. Melton Mowbray probably stands over a concealed coalfield, which has been proved by borings to the north-west, and which may extend far to the south-east.
