EEPOETS OF THE PEOCEEDIXGS OF GEOLOGICAL 

 SOCIETIES. 

 OSWESTRY NATURALISTS' FIELD CLUB. 

 OxV Thursday last, the 29th July, the members and friends of the ahove society 

 made their third excursion for this season. The "field" to be explored was a 

 very interesting one. embracing the coal-measiires and millstone-grit of Sweeney 

 and Treflach, and the mountain-limestone of Treflach and Trefonen, terminating 

 with the Moelydd. 



The members present were : — Mr. J. Meredith, Oswestry ; Rev. D. P. Lewis, 

 Buttington; Rev. F. W. Parker, Welshpool; Rev. J. E. Hill, Welshpool ; Rev. 

 D. Lloyd, Trefonen; Mr. S. W. Williams, Welshpool ; Mr. D. C. Davies, Mr. E. 

 W. Thomas, Mr. S. S. Lees, and Mr. J. Croxon, O.swestry ; Mr. J. Clarke, Brook- 

 house ; and Mr. I. F. Whitridge, Morda. The following gentlemen also attended 

 as visitors; — Mr. J. S. Davies and Mr. Turner, Oswestry ; Mr. Hughes, King's 

 College, London ; and Mr. Stokes, Trefonen. 



The party proceeded by Sweeney Colliery and Gronwen to the locality between 

 Treflach Hall and Sweeney Mountain, where some of the members were interested 

 in observing the line of faults with which the millstone-grit is broken, those 

 faults being there distinctly traceable along the surface. Others commenced a 

 search for the rare fern, Hymenophyllum, said to grow in a wood thereabouts, but 

 were unsuccessful. From thence they wended their way to the quarries in the 

 mountain-limestone at Treflach, where the collectors of fossils soon filled their 

 bags and boxes with the various genera of corals, shells, &c., peculiar to that for- 

 mation. Among others, we noticed a very perfect tooth of Megalichthys. From 

 Treflach the excursionists proceeded in two parties to the Moelydd. The one 

 ascended the hill by the direct route, the other from its base at Nant Mawr, in 

 order to make out the nature and position of the rocks of which the hill is formed. 

 Here again they were rewarded by finding numerous specimens of fossil corals 

 and bivalve shells in the blue shale underlying the mountain-limestone. The gem 

 of all the fossils found during the day, however, was a very perfect specimen of a 

 triiobite found in the blue shale just mentioned, by the Rev. D. P. Lewis, of But- 

 tington, From this shale the members ascended to the igneous rock which flanks 

 the western side of the hill, and having obtained numerous crystals of sulphate 

 of iron, with which that rock is plentifully dotted, they started for the top of the 

 hill, where, in a happy oblivion of tables and chairs, they proceeded to discuss, 

 with a right good will, the bountiful repast laid out on the green sward for them 

 by Mrs. Hughes, of Yr Efel Inn. 



The Rev. F. W. Parker said he was sure it was the feeling of all present, that 

 the meeting ought not to separate without expressing their respect to Mr. Meredith 

 for the deep interest he had taken in the welfare of the Society, and the kindness 

 with which he had assisted the members on the several excursions. He hoped 

 that success and prosperity might attend him in his far-distant home. 



Mr, Meeedith replied that, when far away, nothing would give him greater 

 pleasure than to know that this Society was doing its best to work out what he 

 had begun— the geology of the .district— and he hoped that he should hear from 

 some of the members ; and if ever he returned to England, his first desire would 

 be to visit the Oswestry Naturalists' Field Club, 



Mr. D. C. Davtes proposed that Mr. Meredith should allow his name to be 

 placed on the list of honorary members of the Society, as no one was more worthy 

 of that honour than he was.
