was obtained. Yarious picturesquely weathered rocks were noted, 
and a return was made to Pateley by way of the richly-wooded 
undercliff. 
On Monday morning wagonettes took the party to Upper 
Nidderdale. Short stops were made to inspect the works for the 
compensation reservoir of the Bradford Corporation, and to view 
Gouthwaite Hall, a seventeenth-century house, the old residence 
of the Yorkes, which will probably be destroyed by the new 
reservoir. Near Lofthouse one of the water gushes by which the 
Nidd emerges from its underground course was examined. From 
Lofthouse the dry valley was followed up to Goydon Pot, where 
a short stay was made, and then a visit was paid to Manchester 
Pot, into which, at the time of our visit, the whole of the waters 
of the Upper Nidd were discharged. Ascending the hill to 
Middlesmoor a short cut was taken to How Stean Beck, and the 
beauties of this wonderful little gorge were duly admired. For 
the last mile before joining the Nidd, How Stean Beck rushes 
through a narrow cleft in the Yordale Beds, 70 feet deep, and 
forms a ravine which is a picturesque illustration of torrent 
denudation. The sides of the gorge are hung with mosses and 
ferns, and overshadowed with trees. Eglin's Hole, a chasm on 
the south side of the ravine, was also explored. The return 
journey was made by wagonette to Pateley Bridge. 
The Summer General Meeting was held at Scarborough, on 
Friday, July 9th, and was associated with Field Excursions in 
the neighbourhood on Thursday, Friday and Saturday. On 
Thursday, July 8th, the members united with the geological 
section of the Yorkshire Naturalists' Union in an excursion to 
Hackness. The party were conveyed by wagonettes to Suffield 
Heights, where a quarry in the Coral Rag was examined. The 
route was continued by Hackness Hall to Silpho, where quantities 
of a large gasteropod (Phasianella) Avere found. Rejoining the 
conveyance at Hackness, the party drove down Forge Yalley to 
Ayton quarries in which masses of Thamnastr?ea were found. 
Thence the road by the race course was taken to Scarborough. 
On Friday morning the party met at Castle Hill, under
