240 YORKSHIRE NATURALISTS AT HARROGATE. 



some local student of mosses and hepatics, many additional forms 

 would be found, and those named in this list would probably be 

 gathered in fruit at the proper season. 



The Geological Section was represented by both its secretaries, 

 Mr. S. A. Adamson, F.G.S., Leeds, and Mr. S. Chadwick, F.G.S., 

 Malton, the former of whom reported that the geologists had 

 examined the locality to the north and north-west, by which means 

 three important geological formations were seen to advantage, viz., 

 the Lower Magnesian Limestone of the Permian system, and the 

 Millstone Grits and the Yoredale rocks of Carboniferous age. 

 Accordingly, they proceeded to Nidd Bridge to commence their work. 

 They had, however, an experience altogether novel in being without 

 a leader, the gentleman who had promised to undertake this duty 

 having failed to appear, and so the geologists had at Nidd Bridge to 

 walk over a district entirely new to them, and by study of maps and 

 frequent inquiries of passers-by, to do the best they could. This 

 took time, and at one part of the journey the members lost their 

 way, and had to retrace their steps, causing about two miles of 

 additional walking. The programme was ambitious, but faithfully 

 carried out, yet the delays alluded to made it very late before the 

 whole party reached Harrogate in the evening. 



From Nidd Bridge Station they took the road to Ripley, on the 

 way examining that remarkable boss of Lower Magnesian Limestone 

 known as Nidd Rock. It is not only remarkable as being an outlier 

 of the Permian Rocks, the nearest position of these being some miles 

 away, but more so as it is almost surrounded by one of these terraces 

 of river gravel, which were formed of course when the Nidd flowed 

 at a higher level. This is a very fine example of a river terrace. 

 Strangwayes, in speaking of these terraces, says that 'it is a curious 

 fact connected with them that they all occur just above the 100 con- 

 tour, which is the maximum elevation of the warp clay ; and it would 

 appear from this that they were deposited about the same time, and 

 when the lower portion of the Nidd was under tidal influence as far 

 as Walshford Bridge.' The Limestone here was soft, thickly bedded, 

 and yellowish in colour. The rock, apart from its geology, forms a 

 very pleasing picture. 



They now passed through the quiet and pleasant little town of 

 Ripley, not having time to bestow more than a passing glance at the 

 exterior of its ancient castle and church, but taking the road to 

 Holly Bank Wood on their way to Clint. The scenery along this 

 road was of a charming character. The visit to Clint was to inspect 

 a section of the Cayton Gill beds, so inseparably connected with the 

 name of the Rev. J. S. Tute, Vicar of Markington, who had kindly
