BAGSHOI E£DS OF EAGSHOT HEATH. £) / 



described by Dr. Irving show that tbe clay no. 9 should be 

 carried on northwards. This clay I believe to represent the 

 bottom bed of the Middle Bagshot at Goldsworthy. On 

 that point we are, I think, all agreed, and it is my belief 

 that, so far as this diagram is concerned, the only difference 

 between Dr. Irving and myself is whether this clay crops 

 out south of the place where Mr. Herries and I have marked 

 sand under the letter d, or whether it continues through the 

 hill and crops out a little north of the letter d. 



f). 1887, Dr. Irving, Quart. Journ. Geol. Soc. vol. xliii. p. 38b, 

 fig. 1. In this diagram the anticlinals both north and south 

 of the station are given up and the bedding made horizontal, 

 but I do not agree with this any more than Avith the suppo- 

 sition of anticlinals, for the bed of green sand is well seen in 

 the cutting north of the station as shown in the diagram by 

 Mr. Herries and myself in 1886, whereas Dr. Irving does not 

 allow that it rises above the line. There is also a mistake 

 at the words ' Mne-Mile Eide,' where the railway-cutting is 

 drawn as gravel with a considerable thickness of Middle 

 Bagshot beds below the level of the line ; while in fact the 

 railway-cutting is in Lower Bagshot sand capped by gravel, 

 as has always been contended by Mr. J. H. Blake, Mr. E. S. 

 Herries, and myself, and as Dr. Irving now admits (' Eecent 

 Contributions, &c.' p. 13, note B). 



6. On jN'ov. 12th, 1890, Dr. Irving exhibited at the meeting of 

 the Society a revised version of the sections along the South 

 Eastern Eailway. I regret to say that, owing to the smallness 

 of the scale, I could not see it well enough when speaking 

 to deal with it properly, and my remarks published in this 

 Journal (vol. xlvii. Proc. ■^. 3) referred therefore to the 

 diagram of 1887, no. 5 of the present list, which was also 

 exhibited. At the meeting on June 10th, 1891, the new 

 diagram was exhibited drawn to a large scale, and I took 

 the opportunity of pointing out exactly how far I agreed 

 with it. The chief difference between Dr. Irving and myself 

 seemed to be that to which I have already alluded, viz. 

 whether the basement-bed of the Middle Bagshot seen in 

 the clay pit at the Old Eoman Eoad crops out near the 

 second signal-post north of Wellington College station, or 

 whether it runs on somewhat farther north, and whether the 

 beds at ^Yokingham are Lower Bagshot, as I think, or partly 

 Middle Bagshot, as Dr. Irving contends. The sands in the 

 well c? in the diagram by Mr. Herries and myself^ were 

 certainly clayey, especially in the upper part, but I saw no 

 clay like that in the claypit by the Eoman Eoad. which is a 

 little north of the figure 9 in that diagram. I admit also 

 that there are some loamy sands at Wokingham, but the 

 mere fact that clays occur is not by any means strong 

 evidence against Lower Bagshot age.
