BOOKS AND MAPS.— The whole area for investigation is included in 

 Sheets 94 N.E. (Skipsea) and 94 S E. (Hornsea) of the One-Inch Ordnance Map, 

 which may be had geologically coloured. Fretwell's Illustrated Guide to Hornsea, 

 N.D., 6d., contains chapters on the Flora by Mr. J. F. Robinson, the Geology by 

 Mr. J. W. Stather, and the MoUusca by Mr. F. W. Fierke. The Naturalist for 

 July 1881, pp. 194-6, contains full reports of the work done by the Union on its 

 visit to Hornsea in June 1881. 



THE DISTRICT to be investigated consists of the neighbourhood of 

 Hornsea Mere, the remarkable earthworks at Skipsea Brough, and the coast line 

 from Skipsea to Hornsea. 



ROUTES.— 



I. — The Geological Party will leave Hornsea Station immediately after arrival 

 of the 10-35 ^-i"- train, and proceed in conveyances (i/- each) to Skipsea. Members 

 desiring a seat should communicate with Miss Rose Carr, Waggonette Proprietor, 

 Hornsea, not later than Thursday, 17th May. 



On arrival at Skipsea the earthworks at Skipsea Brough will be examined and 

 explained by Mr. J. R. Boyle, F. S. A., and the party will then proceed to the shore, 

 and work back to Hornsea, under the leadership of Messrs. J. W. Stather, F.G.S., 

 and F. F. Walton, F. G. S. , who will be accompanied by Mr. William Morfitt, of 

 Atwick, and his sons. 



2. — The Sheffield Naturalists' Club Party are making their own arrangements, 

 not being able to arrive in time to join Route i. 



3. — The general body of naturalists will investigate Hornsea Mere. Leaders : 

 Members of the Hull Scientific Club. Boats may be hired from the boat-house at 

 i/- per boat per hour. 



4. — Geologists arriving by later trains are recommended to proceed along 

 the shore northwards to meet the main party. 



5. — Naturalists arriving by later trains are recommended to leave the train at 

 Hornsea Bridge Station, and join the main body in the vicinity of the Mere. 



6. — Marine Zoology. The Yorkshire Marine Zoology Committee will investi- 

 gate the shore-line. 



PERMISSION for Hornsea Mere is granted by Mr. H. S. Constable, J. P., 

 and for Skipsea Brough by Mr. C. Goodlass. 



LOW- WATER will be at 1-6 p.m. on Friday, 1-48 p.m. on Saturday, and 

 2-30 p.m. on Sunday. 



Mr. W. Morfitt's collection at Charlotte Cottage, Atwick will be open 

 to inspection by members staying over the week-end. Mr. E. Howarth furnishes 

 the following notes on them : — 



From the Peatbeds and boulder clay between Skipsea and Hornsea have been 

 collected many interesting fossils by Mr. Wm. Morfitt and his two sons, of Atwick, 

 and an inspection of their collections will aid materially in a full understanding of 

 the coast geology of the district. Besides a large number of derived fossils, 

 belonging to the chalk and lias chiefly, they have found in the peat and clay tusks 

 and teeth of Mammoth, teeth of Elephas antiquus, as well as remains of Irish 

 Elk, Reindeer, Red-deer, and Rhinoceros. Many interesting antiquities have also 

 been collected by them from the neighbouring barrows. 



GEOLOGY.— Mr. J. W. Stather, F.G.S., President of the Hull Geological 

 Society, writes : — With the exception of certain deposits of later date, Holderness 

 is entirely composed of glacial accumulations, the joint product of native and 

 Scandinavian glaciers, during the great ice age ; and there seems no doubt, that 

 before the ice reached our shores, the district was a wide bay, with the sea running 

 quite up to the foot of the Wolds, its shore line approximating to the present course 

 of the railway from Hull to Bridlington. The cliff sections between Skipsea and 

 Hornsea, which the geological party propose to visit, are fairly typical of the 

 whole coast line of Holderness. 



Post Glacial Deposits. — On the shore opposite Skipsea, and resting on 

 boulder clay, will be seen an extensive deposit of fresh water marls, peat, etc., 

 marking a time when Holderness was occupied by a series of meres, of which 

 Hornsea mere is the only remaining example. A deposit of a similar kind occurs 

 on the beach at Hornsea and can be seen at low tide, if not covered by the shiftmg 

 beach material. Fossil shells occur in these marls, for list of which see Mr, Fierke's 

 notes on another page of this page this circular.
