GEOLOGY.— Rev. E. Maule Cole, M.A., F.G.S., writes the following: — 

 Taking the Cock Beck for our guide, the whole of its bed lies on the Lower 

 Magnesian Limestone, the Upper Limestone and the Middle Red Marls, which 

 flank its sides, having been completely cut through. The main portion of the 

 Upper Limestones, which is extensively quarried for agricultural purposes, lies to 

 the East of the Cock Beck. It is, as a rule, unfossiliferous. Mr. Hudleston 

 notices that in Towton Field occurs 'a form of Magnesian Limestone which is con- 

 cretionary* in small ovoids, almost resembling an oolite.' The Middle Red Marls, 

 being very friable, are easily cut through, and initiate valleys — one such stretching 

 from Sherburn to Huddleston. The famous Huddleston quarry, from which the 

 choir of York Minster was built, is in the Lower Limestones, which there are 

 dolomitic. The best point for examining the Middle Red Marls is the railway 

 cutting between Tadcaster and Stutton. The Upper Red Marls occur in Grimston 

 Park, and just North and East of the village of Towton. The moraines at Wig- 

 hill and Healaugh, portions of the lateral moraine of the Wensleydale glacier, are 

 worthy of notice. Wighill Church stands on one and commands a fine prospect. 



BOTANY.— In Davis and Lees' 'West Yorkshire,' 1878, there are no precise 

 indications as to the Florula of this immediate tract, but a short list of 36 species 

 collected here in August 1881, is given by Messrs. F. Arnold Lees and W. West 

 (Nat., Nov. 1 88 1, p. 60). 



Flowering Plants. — Mr. W. Ingham, B. A. , York, notes that in Jackdaw Crag 

 Quarry, about the middle, Draba verna var. brachycarpa Jord. , will be found in fruit.

*This seems to me to correspond with the horizon of the celebrated concretionary beds on the 

 Durham Coast at Monk Wearraouth, which however consist of larger nodules.
