a great altitude, and a little lower a good and very long band of Pliocene teds of 

 marine and continental origin. Quaternary deposits, similarly continental and 

 littoral, occur lying along the actual coast, pointing out the south side of the 

 Mediterranean connection. 



In a few words, the English Channel has been opened very recently, and no sea 

 occupied its place before. No sea has crossed France or central Spain, and we are 

 obliged to seek for an outlet for the Eastern Sea during Miocene time by way of 

 Germany, Galicia, and South Russia, or by the north of Scotland. 



During the existence of the Pliocene seas there w.as no other communication 

 for the Crag seas than the northern one, for the western, the south, and eastern 

 sides were undoubtedly shut in by land.

The general geological features of these now famous deposits are more or 

 less familiar to most readers. The beds of the ' Main Keef Series ' have been 

 closely studied from one end of the Ptand to the other, and are now being worked 

 in an almost continuous series of prosperous gold -mining companies, the whole 

 distance covered by mines in active operation amounting to forty-six miles. The 

 beds have the usual characteristics of conglomerates, being composed of pebbles
