THE PEA GRIT OF CLEEVE HILL. 



Sir, — I thank Mr. Witchell for his courteous correction of my 

 figures in the thickness of the Pea-grit, and underlying Ferruginous 

 Oolite in the Cleeve Hill Section, which I quoted in my letter in the 

 Geological Magazine for November last. The error occurred in 

 the numbers of the beds being inserted as feet, and the three figures 

 ■were transferred to the inch column. Mr. Witchell remarks that 

 " the correct reading confirms my statement, except as regards 

 the lowest 5 feet." Exactly, but the exception makes all the dif- 

 ference ; if there are only 5 feet of Oolite under the Pea-grit beds at 

 Cleeve Hill, then Dr. "Wright could not make the thickness more, 

 and as I understand Mr. Witchell, in his paper in the Quarterly 

 Journal of the Geological Society, he maintains that the basement 

 beds were overlooked by Dr. Wright. Mr. Witchell in his paper 

 says, "The beds next above the Cephalopoda-bed are usually brown 

 sandy limestones in two or three beds, varying in thickness from 

 5 feet at Cleeve Hill." ^ 



Now I think it would have been fairer to Dr. Wright if Mr. 

 Witchell had given a reference to Dr. Wright's Cleeve Hill section 

 where that fact was first mentioned. Doubtless in the Stroud area 

 the basement beds assume a greater importance than Dr. Wright 

 recognized, but of course he had to be guided by the available 

 exposures of the strata in his day. 



I do not think I need argue the matter further, as Mr. Witchell 

 seems to me to admit my contention, viz. that the late Dr. Wright 

 in his sections of Cleeve Hill and Leckhampton showed that there 

 were Oolitic beds below the Pea-grit proper. Ebward Wethered. 



THE COLLINGHAM OR SCARLE BORING. 



Sir, — The altei-native figures, given by me, as Eeporter to the 

 British Association Underground Water Committee, on the authority 

 of Mr. W. H. Dalton, are correctly copied from a lithographed copy 

 of a report by him to the Gainsborough Board of Health, " On the 

 Water Supply obtained from Underground Sources at Gainsborough," 

 handed to me by the Board on the 24th of October, 1884, and now 

 before me. 



On the 1st of November, of that year, I recommended the Board 

 to sink an artesian boring at Gainsborough to a depth of 750 feet : 

 this proposal was adopted, and I have to-day learnt by telegraph 

 that the contractors, Messrs. Timmins, of Euncorn, have penetrated 

 the Keuper Marls, and reached the Sandstone at a depth of 725 feet 

 from the surface. C. E. De Eanoe.

 Sir, — Mr. John Griffiths, of Folkestone, the well-known collector
