24 PROF. T. G. BONNEt ON THE NARBOROUGH DISTRICT. [Feb. 1895. 



•3. Supplementary Note on the Narborough District (Leicester- 

 shire). By T. G. Bonnet, D.Sc, LL.D., F.R.S., F.G.S., 

 Professor of Geology in University College, London, and 

 Fellow of St. John's College, Cambridge. (Read December 5th, 

 1894.) 



The outcrops of crystalline rock in the Narborough district were 

 described, in 1878, by the Rev. Edwin Hill and myself in the 

 second of our papers on Charnwood Forest. 1 Since that time the 

 old quarries have been much enlarged and others have been opened. 

 These, one hoped, might have disclosed some new facts, and increased 

 experience might occasionally suggest a different interpretation of 

 things already seen. Hence I became anxious to pay a parting 

 visit to the district before it passed, so to say, into other hands, and 

 spent two or three days there in the Easter holidays of 1893, 2 

 without, however, the advantage of my friend's companionship, for 

 just at that time he was unable to leave home. 



On our former visits we had not succeeded in finding either any 

 dykes cutting the crystalline masses, 3 or more than one junction 

 between the latter and the sedimentary rocks of the Forest series. 

 I had hoped that in the process of quarrying some of the one and 

 more cases of the other might have been discovered. But I was 

 disappointed in both respects, though additional information was 

 obtained as to the junction already known in the neighbourhood of 

 Enderby. Some of the pits also afforded rather interesting sections 

 of Boulder Clay. There is, however, so little to record 4 that the 

 fact of our former papers having appeared in this Journal alone 

 emboldens me to submit this supplementary note to the Society. 



The quarries near the villages of Enderby, Croft, Huncote, Stony 

 Stanton, and Sapcote, though now more numerous and often 

 greatly enlarged, furnished nothing new of any importance. In 

 a disused pit nearly south of the windmill at Stanton Fields, near 

 Sapcote, I observed on the quarried face one or two patches of 

 a darker coloured rock, 2 or 3 inches in diameter, which probably 

 were nodes, and was shown by the manager of a pit, north of the 



1 Quart. Journ. Geol. Soc. vol. xxxiv. (1878) p. 225. 



2 After writing this paper, 1 visited some of the places near Narborough 

 (in September last) and found that a pit had been opened in a new locality, 

 as described in the text. 



3 Dykes in the hornblendic granite and the ' syenite' of Charnwood Forest 

 are described by us, op. cit. pp. l!20-224. 



4 The increased size and especially depth of the pits, and the amount of work 

 which is carried on, make it almost impossible to examine some of them. 

 When the bottom of a pit was practically inaccessible, I walked round the edge, 

 examined the stone brought up, and made enquiries from foreman or manager, 

 as to whether the rock had been found to vary. I got no hint of the discovery 

 of a dyke or of a new junction.
