THE DISTRICT to be investigate-] consists of the neighbourhood of Hornsea 
Mere, the remarkable earthworks at Skipsea Brough, and the coast line from 
Skipsea to Aldborough. 
HEADQUARTERS.— The Alexandra Hotel, Hornsea. Terms : 6/6 per day, 
including bed, breakfast, dinner, and tea. 
All available rooms at the hotel, some of which are double-bedded, have been 
secured by Mr, Sheppard, to whom application should be made at once. It will be 
useless applying to the hotel. The rooms will be apportioned in the order of 
application. 
EVENING MEETINGS.— These will be held in a room set apart in the hotel. 
ROUTES. — These will be left in the hands of leaders of sections. Notices will 
be left at the hotel for later arrivals. 
The Mere and its surroundings will probably appeal to the general body of 
naturalists ; the coast to geologists and marine zoologists. 
Sat. June 6th. On the arrival of the train from Hull at 10-28, a party 
will walk along the coast to Aldborough for the examination of the cliff 
sections. Members arriving by later trains should walk along the coast, south- 
wards, to meet the earlier party returning. 
June 7th. — The fauna and flora of the Mere will be investigated. The |;ravel 
terraces will be of interest to geologists. 
Whit-Monday, June 8th. — On the arrival at 9-52, of the train leaving Hull at 
9-16, the party will proceed northwards to Skipsea Brough. Conveyances will 
meet the train ; fare i/-. The remarkable prehistoric earthworks will be exam- 
ined, and described by Mr. Sheppard. 
Members desiring to investigate'the Mere are recommended to leave the train 
at Hornsea Bridge Station. 
Members of the Hull Scientific and Field Naturalists' Club, and of the Hull 
Geological Society will act as leaders. 
PERMISSION for Hornsea Mere is granted by Mr. H. S. Constable, J. P., 
and for Skipsea Brough by Mr. C. Goodlass. 
GEOLOGY. — The Geological Section will be officially represented by Mr. 
J. W. Stather, F.G.S., and Mr. T. Sheppard, F.G.S. 
Mr. j. W. Stather writes : — With the exception of certain deposits of later 
date, Hornsea 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 (juite up to the foot of the wolds, its shore line roughly coinciding with 
the present line of railway from Hull to Bridlington. The long cliff sections north 
and south of Hornsea are among the best exposures of lowland drift in Britain, or 
even in Europe, and are well worth careful study. 
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 lime when Holderness was occu})ied by a series of meres, of which 
Hornsea Mere is the only remaining example. Deposits of a similar kind occur on 
the beach at Hornsea, and also on the cliff at Hornsea Burton. For lists of fish, 
shell and plant remains from these deposits, see Mr. Sheppard's paper in "The 
Naturalist," December, 1906. 
Glacial Beds. — It w ill be noted that the coast sections, though much obscured 
by slips, show distinct bands of boulder clay, separated by irregular deposits of silt 
and gravel. The clays are full of boulders, many of them beautifully striated, from
