NATURALISTS IN SOUTH LINCOLNSHIRE. 



Rev. EDWARD ADRIAN WOODRUFFE-PEACOCK. L.Th.. F.L.S.. F.G.S.. 

 Vicar of Cadney ; Organising and Botanical Secretary, Lincolnshire Naturalists' Union. 



The twenty-ninth field meeting- of the Lincolnshire Union was 

 held in the episcopal city on Saturday, 29th September 1900. 

 The unusual cataclysm of the general election kept many well- 

 known members away ; and the day proved anything- but a 

 fruitful one, though it was as lovely as could be desired. 



Leaving Lincoln the party arrived at Harmston Station at 

 10.21, and followed the footpath by the railway to the south of 

 the station. Leaving the line they .passed through Coleby 

 village, visiting a disused brickyard and small quarry. Passing 

 to the east of Boothby Graffoe they followed the line of the cliff 

 road to Navenby. After inspecting another quarry and brick- 

 yard, Lincoln was reached by train from Navenby Station, and 

 a jolly if small party assembled for tea at the Saracen's Head. 



Mr. H. Preston, F. G.S., reports : — To the geologist the day 

 proved very instructive, as we were able to examine several 

 interesting sections ranging from the Middle Lias upwards to 

 the Lincolnshire Limestone (Inferior Oolite). At Coleby a section 

 5 feet thick occurs in the village street, which shows a massive, 

 sandy, ferruginous limestone belonging to the Northampton 

 Sands series. This rock underlies limestone of the Inferior 

 Oolite series, and the junction of the two beds is well seen 

 where the section forms the base of a stone wall. A limestone 

 quarry in the same village was visited, and some good Phola- 

 domya and Modiola were found, chiefly in the marly partings 

 between the limestone bands ; whilst a fragment of a crustacean 

 (Eryma ?) was obtained from the solid limestone bed. 



At Boothby Graffoe a similar quarry in the Lincolnshire 

 Limestone yielded Pinna cuneata amongst other things ; and it 

 was interesting to notice in this quarry the changes which are 

 coming on in the character of the limestone beds. These 

 changes are noticeable in the numerous clay and marly partings 

 which occur between the more massive beds of limestone, and 

 in the bands of pale grey, whitish, impure, nodular limestone 

 which are seen here and at Coleby. These limestones are much 

 more massive in the southern part of the county, and the 

 changes which were seen in this quarry increase as we travel 

 northwards until the Lincolnshire Limestone is divisible into an 

 upper and lower group just before entering Yorkshire, known 

 as the Hibaldstow and the Kirton beds.
