172 GEOLOGICAL EXCURSIONS. [l862. 



and the Victoria Cave, and where he found his way 

 again to Cefn and Llangollen. During the first week 

 in August he was in the eastern counties, working from 

 pit to pit.

MY DEAR EVANS, I hope to go to Auvergne next week early. 

 I shall spend a day in Paris. When Daubre*e was here he 

 expressed a great wish to get a copy of your paper. I don't 

 know which. He said he saw it at Babbage's. Can I take a 

 copy over for him? 



I have had a very pleasant excursion north. I was a day at 

 Settle, and saw the Victoria and other caves, and the collection 

 of British and Koman antiquities of Mr Jackson. I also spent 

 a day at Salop and Wroxeter. I have since been to Colchester 

 and Saffron Walden. I there saw at the enclosed address a 

 so-called British coin, but it appeared to me to be too fresh and 

 sharp, and the metal too undecided. The device was all right. 



A fortnight's tour in Auvergne, beginning on the 

 12th August, was one of keen enjoyment, the volcanic 

 character of the ground traversed being of special 

 interest. Towards its close our geologist summarised 

 in a sentence : 



The general features of this excursion so far are the un- 

 disturbed position of the scoria, the slight decomposition of 

 the lava, the . great decomposition of the granite and gneiss, 

 and the considerable decomposition of the trachytes, and the 

 absence of drift. 



J. Prestwich to J. Evans. LONDON, 22nd September 1862. 



MY DEAR EVANS, You deserve your excellent sight from the 

 excellent use to which you apply it. I fancy I can do pretty 

 well in a state of rest, but for geology in motion none equal you. 

 It is truly progressive geology. I am glad you have traced the 

 source of the gravel. I am quite ready for the hunt. Shall it 

 be direct, or from Cambridge ? Orton should be visited again.
