There is a very good section on the line side a few hundred 

 yards west of South Cave railway station, which may be 

 regarded as a typical one. The rock is strongly current-bedded 

 — a huge mass two feet in depth suddenly tapers off, and within 

 a short distance from its thickest part it is reduced to a few 

 inches in depth. The limestone is usually of a crumbly nature, 

 though, as already stated, fairly solid masses are to be met 

 with. When weathered the Millepore is of a light yellow 

 colour, and in places of a sandy texture ; but on breaking open 

 some of the larger lumps they are found to be blue-hearted, and 

 these unweathered portions are very tough and the fossils are 

 with difficulty extracted. At this railway section various fossils 

 can be collected, but with greater ease and success in the small 

 gullies down which the weathered material has been washed, as 

 in these gullies a process of natural selection has taken place, 

 to the great advantage of the collector. Terebratulce, Li?na, 

 Pecten, Pinna, and remains of Echinoderms are common, and 

 now and then a Turbo or other univalve can be picked up. 



Good sections in the Millepore also occur in a field between 

 South Cave and Hotham. The beds here are alternately of 

 sandstone and limestone ; the latter having a peculiar nodular 

 appearance. Fossils are numerous, pretty little echinoderms 

 being amongst the best from a collector's standpoint. Amongst 

 univalves should be mentioned Chemnitzia, Cerithium, and 

 Turbo ; whilst bivalves are represented by Avicula, Rhyuchonella, 

 Tercbratula , Modiola, Trigonia, Lima, etc. Pentacrinus, Serpula, 

 and a host of other interesting remains are also to be obtained.* 

 There are remains of very extensive excavations here ; and it is 

 said that from this place the stone for parts of Beverley 

 Minster was obtained. 



In the 'Cockle Pits,' near Brough, some good solid beds of 

 Millepore Limestone are exposed. These were formerly exten- 

 sively quarried for material required in connection with the 

 construction of one of the Hull docks ; but whilst quarrying 

 operations were going on water was struck and rushed in upon 

 the workmen, who with difficulty escaped. The barrows and 

 tools, or what is left of them, still lie at the bottom of the pond 

 which occupies the centre of the excavation. 



An interesting exposure in the Millepore Oolite has recently 

 been made in the northern end of Prescott's Pit. Below the 

 gravel a deep cut has been dug which shows in a remarkably
