YORKSHIRE NATURALISTS AT HARROGATE. 241 



written informing us of this section, which certainly is a fine one. 

 It receives its name from the good exposures to be seen in Cayton 

 Gill, a few miles north of Ripley. Geologically it belongs to the Third 

 Grits of the Millstone Grits series, and its position is between the 

 Plompton and the Follifoot Grits. It is a hard calcareous sandstone, 

 and is highly fossiliferous, the bed being literally one mass of fossils. 

 There were quantities of Produdus semireiiadaius, Spiriferce, Orthis, 

 stems of Encrinites, BelleropIio?i, Aviculopecten, etc., and one member 

 found what seemed to be a remnant of Fenestel/a. It was a rich 

 harvest for the fossil collectors, and bags began to acquire weight. 

 There are several other good sections in the neighbourhood, par- 

 ticularly in a quarry at Hampsthwaite and in the railway cutting near 

 the station. And now the contretemps occurred which lost the party 

 some time. Still, after all, there was the consolation of walking 

 through leafy lanes and inhaling the perfume of the honeysuckle and 

 the new-mown hay. After a time, when the spires of Harrogate were 

 receding from view, and the geologists knew they must be wrong, 

 'right about' was called, they retraced their steps, the fields, the 

 railway, and the river were crossed in turn, and presently they were 

 in the pleasantly-situated village of Hampsthwaite. 



It was now felt that, after so many miles of walking, some rest 

 and refreshment were imperative. This was soon found at Miss Haw's 

 cosy and comfortable hostelry. After partaking of the im- 

 promptu fare so well provided, it was felt that, although there was 

 no appointed leader, and none of the party had traversed the ground 

 before, yet something should be said by someone as to the geology 

 passed over and also of the remainder of the route. Accordingly 

 Mr. Adamson gave an address in the room of the village inn bearing 

 upon these matters, giving first the stratigraphy of the whole district, 

 then describing each bed in detail, with localities for sections. He also 

 spoke upon the unique geology of Harrogate, and described the great 

 anticlinal to which is due the prosperity of that town. The opinion 

 was expressed that these remarks were most timely, and had done much 

 to lessen the difficulty in which they were placed by being leaderless. 

 In answer to a question it was stated that the rocks now being travelled 

 over were the Third Grits, the highest in this district of the Millstone 

 Grits series. Where then were those rocks which it is known occur 

 between the Permians and the Third Grits, viz., the Coal Measures, 

 the Rough Rock, &c. ? These have been removed by denudation 

 before the Permians were laid down, and although we had had 

 conclusive proof of extensive denudation at Nidd Rock, this was a 

 more remarkable and immeasurably grander example of this familiar 

 geological agency. After other questions had been asked and
