Nine years earlier than the date of the above quotation from 

 De la Beche, Jolm Alsop makes the following significant statement: ' 

 " In a section of Crick [Crich] cliff, what is at one shaft a thin bed 

 of clay a foot thick, becomes within a short distance fourteen feet 

 thick, and contains large nodules of compact toadstone [italics

I have also been informed that the late A. H. Stokes, F.Gr.S., 

 H.M. Inspector of Mines, held the opinion that the clays above 

 described were of igneous origin. 



If, then, these clays represent lava-flows, or possibly in some cases 

 tuffs, the interesting question follows, where was the vent situated 

 from which they were erupted ? With the Editor's permission 

 I propose to discuss this question in a subsequent paper.

IN 1911 Mr. E. J. Wayland, F.G.S. , and the authors visited the 

 Portuguese East African province of Mozambique in the interests 

 of the Memba Minerals, Ltd. The country was very little known 

 geographically, and except along the coast, it was a terra incognita 

 to geologists. We hope in due course to publish a detailed account 

 of our observations, but as it will be some time before this can be 

 completed, it seems advisable to give a short resume of the salient 

 geological features of the territory. It is hoped that these results
