196 NOTES ORNITHOLOGY. 



On behalf of the Geological Section one of its Secretaries, 

 Rev. W. Lower Carter, M.A., F.G.S., reported that the geological 

 party, under the guidance of Mr. Kirkby, of Ripon, after inspecting 

 the ancient church of Tanfield, with its interesting monuments and 

 Marmion s Tower, started by the field path for Hackfall. The path 

 gave very picturesque views of the gorge of the Ure, which is 

 beautifully wooded, and the wood anemones, celandines, and other 

 wild flowers made the wood gay with their delicate blooms. Very 

 little geological investigation was attempted, but the lessons of 

 denudation exhibited in the excavation were noted. Old river 

 terraces were noted, and at one point, near Mickley, where a little 

 stream joins the Ure, the parallel terraces of this tributary were very 

 plain. The bedding of the Third Grits exhibited in the gorge was 

 fairly horizontal, and the finer flaggy beds exposed in a quarry were 

 found to be very micaceous and false bedded. Banks of coarse 

 detritus were exposed at several bends of the river, which were 

 probably glacial deposits. On the return journey to Ripon a detour 

 was taken to the banks of the Ure, where extensive deposits of 

 gypseous marls had been dissected by the river. Several sections 

 are shown with the marls and interbedded seams of fibrous gypsum 

 contorted in the most violent way. The way in which bands of 

 gypsum, widely separated, in a few feet run together at a sharp angle 

 was very interesting, and the whole problem of the contortion of 

 these beds is difficult of solution. Distant glimpses were also 

 obtained of some of the pits of subsidence which lie parallel to the 

 river course, and which are probably due to the solution of portions 

 of the underlying Magnesian Limestone. 



A vote of thanks to the chairman was then passed, on the motion 

 of the Rev. W. Fowler, M. A., in replying to which Mr. Crowther read 

 an interesting short paper on the study of natural history in the field.

Barred Warbler in East Yorkshire.— A fine adult female of Sylvia msorti* 



was shot last summer at Skiriaugh in Holderness, by Mr. Darley, Taxidermist* 

 Hull. It is now in the York Museum* I understand that two or three years ago 

 another of these very rare migrants was shot near Patrington in South Holderness. 

 Gatke considers this species the rarest of the German warblers visiting Heligoland. 

 In England he states that this bird has not been met with up to the date of his- 

 work. However, four or five instances have occurred. — B. B. Haworth-Booth* 

 Iiullbank Hall, near Hull, 9th March, 1896. 



The date of this interesting occurrence would be valuable. — Ed. 



Flarnbo rough Bird-Notes.— Dotterels (Eudromias morinellus) are very 

 scarce this season. Mr. D. Arkii m informs me that he has only seen twenty 

 Dotterels in a flock this year in the neighbourhood of Arram Mill. The first 

 Swift {Cypselus opus) that I have seen this season was on June 1st, 1896 A 

 Black Guillemot, or Puffin, has been seen by the fishermen here on the c *t, and 

 makes them nearly wild to know what sort of a bird it is. I imagine it is the Black 



Guillemot {Una &}.— M a hew Bailey, Flamborough, June 20th, t89&.
