JET. 67.] TENBY. 301 



Oxford term over, Prestwich, avoiding the gaieties 

 of Commemoration, set out again for St David's, his 

 wife (with great misgivings as to the effect of over- 

 fatigue) accompanying him. The first stage was 

 Newnham-on-Severn, the expedition from there being 

 to Garden Cliff a classical spot where, although only 

 slight traces of Northern Drift could be seen on its 

 summit, the section was very fine, being New Red 

 Marl banded with sage-green layers. The fields on 

 the same level, or a little higher, showed Drift pebbles.

 of Great and Little Hoyle, which Prestwich saw under 

 the guidance of Mr E. Laws Black Rock quarry, 

 also near Tenby, and in which a fissure had yielded 

 mammalian remains, being explored at the same time. 

 He had intended to cross to Caldy Island to examine 

 the site where hippopotamus and other fossil bones 

 had been exhumed, but, to the relief of his companion, 

 the continuance of very rough weather and high seas 

 made this expedition impossible. It was only on being 

 assured that landing on Caldy Island could not be 

 effected that a visit to it was most unwillingly given up. 

 Good-bye was said to Mr Laws near Lamphey Station, 

 the travellers proceeding by Manorbeer and Pembroke 

 to Haverfordwest thankful in a chilly evening to find 

 a close carriage waiting them from St David's. 



Whitesand Bay first engaged Prestwich's attention, 

 and detailed sketches of it were made at different 

 points, including a general section which included the 

 Lingula Flags. On the way back to St David's he
