THE LINCOLNSHIRE NATURALISTS' UNION 



BOULDER COMMITTEE. 



REV. W. TUCKWELL, 

 Secretary of the Committee; IVattham Rectory, Great Grimsby 



Early in this year a Committee was appointed by the Lincolnshire 

 Naturalists 7 Union for the purpose of recording all the facts they 

 can collect about the erratics left by the great ice-sheet that once 

 overspread the county. It consists of the following members : — 

 F. M. Burton, F.G.S. ; J. H. Cooke, B.Sc, F.G.S. ; H. Preston, 

 F.G.S. ; A. W. Rowe, F.G.S. ; Percy R Kendall, F.G.S. ; E. A. 

 Woodruffe-Peacock, F.G.S. ; with the writer acting as Secretary. 

 A circular was sent out, and over 200 boulders are now recorded. 

 Many of these remain unvisited yet, but it seems time to send out 

 a first report, the others remaining over for our next. For the 

 Barton and South Ferriby records we have to thank an admirable 

 observer, Mr. T. Sheppard, of Hull. The notes on the Louth 

 rocks, which I visited with him and with Professor Kendall are also 

 from his pen. Please observe (1) the boulder of Augite syenite (or 

 possibly Elasolite syenite) at Thorpe Hall. It is the largest yet 

 recorded, though we think we are on the scent of a bigger specimen. 

 Captain Tennyson is kind enough to promise, as I understand, 

 that he will protect it. (2) Three blocks of Shap-granite, not 

 previously found south of the Humber.
