Extract

The quarrying operations that have been carried out during the last five years at Handley's Pit, Lincoln, have led to the exposure of some very complete and instructive sections in the Middle Lias.

Handley's Pit is situate on the North Cliff, at a distance of about a furlong from the now disused pit of Glaisiers, and immediately below that of the Lincoln Brick Company (late Swan's). When compared with the sequence exposed in Swan's Pit, it affords some interesting details that assist materially in clearing up some of the doubtful points to which Mr. Dalton referred in the Geological Survey Memoir on Lincoln Geology regarding the limitation of the range of A. margaritatus, and the occurrence of the Marlstone Rock-bed in the Lincoln District.
