LINCOLNSHIRE BOULDERS 



THOMAS SHEPPARD. 



I am pleased to have had such a number of applications for 

 specimens of Shap Granite, etc., in response to the offer contained 

 m my note respecting the boulders of Lincolnshire, which appeared 

 in this magazine for last month. 



With regard to the boulder at Yarborough, referred to in the first 

 paragraph on page 335, Mr. J. H. Cooke^B.Sc., F.G.S. (Hon. Sec. 

 of the Geological Section of the Lincolnshire Naturalists' Union), 

 has examined this boulder and sent me a chip therefrom. It is not 

 1 Shap ' Granite. 



The same gentleman also informs me that he has found two or 

 three boulders of Shap Granite at Goxhill during the last few days. 

 This confirms the suggestion that boulders of this particular granite 

 occur in plenty in Lincolnshire, and that ' they only require looking 

 for' ('Naturalist/ November 1896, page 355). Mr. Cooke will 

 publish detailed particulars of these and other erratics which he has 

 observed, in the next report of the Lincolnshire Boulder Committee. 



Seeing that so many geologists are interesting themselves in the 

 boulders of Lincolnshire, the following list of papers, etc., referring 

 thereto, may be of some service : —
