CiRC- No. 133. 

 2. — The gamekeeper (Mr. James Sumner) and his son and Mr. Wm. Hewett will 

 lead a party of Entomologists to investigate the woods on the Everingham 

 Estate, starting from Everingham Station on the arrival of the 10-15 a.m. train 

 from Selby and the 10-48 a.m. train from ISIarket Weighton (stojiped specially 

 to set down). This party will return by the same train as the first one. 



3. — The Geological party will meet at Market Weighton Station at 1042 a.m. 

 and under the direction of Mr. F. F. Walton, F.G.S., President of the Hull 

 fieological Society, will work the Sancton and Newbald district, returning to 

 Market Weighton via North Cliff. 



CONVEYANCES, is. each, from Everingham Church to Station, in the 

 afternoon, will be provided, but only for members who advise Mr. Marshall 

 in advance that they will require them. 



GEOLOGY. — The Geological section will be officially represented by its 

 President, Mr. Wm. Home, F. G. S., and its Secretaries, Rev. W. Lower Caiter, 

 M.A., F.G.S., and Mr. J. W. Stather, F.G.S. 



Mr. J. W. Stather, F. G.S., writes as follows : — A glance at the map shows 

 that though the geological structure of the country along the base of the wolds 

 south of Slarket Weighton is extremely simple, the outcropping beds are exceed- 

 ingly varied and interesting in character, ranging from the Trias to the Chalk. 

 The Jurassic beds run roughly N.N.W. and S.S. E. , and three faults are marked 

 by Tate and Blake as cutting at right angles across the strike, in the direcfion of 

 the valleys which penetrate the Chalk, by the villages of Drewton, Newbald, and 

 Sancton. In the vicinity of North Cliff, the Lower Lias has been worked in 

 several places for marling the land, and it is here that the character of the beds 

 can be best studied. In a general way the beds exposed may be described as con- 

 sisting of a thick bed of Limestone at the top, full of Lima gigantea, Cardinia 

 listeri. and Ammonites johnstoni ; below this are softer beds, not generally so well 

 seen, and then beds of Limestone again, very full of Osirea, forming regular oyster 

 beds, below which there are more shales and thin Limestones, the lowest being full 

 ■oi I knroiiiya crotocombeia and Modio/a minima. A detailed account of several of 

 the sections has been given by Prof. Blake (Quart. Journ. Geol. Soc, vol. xxviii.). 

 The Oolites, which disappear near Acklam, reappear from under the Chalk in the 

 neighbourhood of Sancton. Twenty feet of the unfossiliferous Kelloways Sands, 

 full of glistening mica plates, are visible in the lo.ver part of the pit, near the
