Note 84a — Chapter VII · GEOLOGICAL NOTES.

The exception to which allusion is here made is the village of South Scarle, about six miles from Lincoln, where a deep boring was made in 1876, in search of coal. The depth attained was 2,029 feet, or nearly twice that of the Woodhall well; but as only the upper layer of the coal measures was thus reached, and it was calculated that actual coal would be some 1,600 feet lower still, or a total depth of 3,600 feet, the boring was abandoned. The strata passed through were found to be as follows: Alluvial or drift, 10ft.; lower lias clay and limestone, 65ft. rhœtic beds, 66ft.; the three triassic formations, new red marl (Keuper), lower keuper sandstone, new red sandstone, 1,359ft.; upper permian marls, upper magnesian limestone, middle permian marls, lower magnesian limestone, permian marl slates, with basement of breccia, 619ft.; and upper coal measures, 10ft.; total, 2,029ft.
