consent to this, I would fix upon certaiu lines of section and send down a rough 

 profile outline to be im]3roved and corrected by yourself. I wish this had been 

 dons many years since, but I cannot call back what is past. Your improved map 

 of Skiddaw Forest (made many years since) I have in my drawer, and I hope to 

 make it the foundation of a separate memoir for the Geological Society this spring. 

 I should also be obliged for a list of the mines now working in your country, and 

 of the nature and quantity of their produce. Much has been done in this way 

 since my walks in Cumberland, and no one knows the subject so well as you. I 

 have often visited Coniston, which of late years has become a great mining countrj^ ; 

 and all the facts I want I could procure from JMr. Taylor. Not that I mean to 

 enter at large on mines or mining, — only to give the leading facts, mineral and 

 statistical, in a note or appendix to some chapter or chapters. Has anj'thing been 

 done of late years in the centre of Skiddaw Forest ? When I was there the veins 

 were not worked, except for procuring minerals, of which there were many curious 

 specimens, such as Wolfram, Tungstate of Lime, Apatite, Schorl, &c., &c. But I 

 consider the facts respecting the mineral veins of less importance to my intended 

 work, than the profiles I have mentioned. There is another subject I often thought 

 of writing about while I was rambling during the two last summers with J. Euth- 

 ven of Kendal. He told me that my letters, published in Mr. Hudson's Guide to 

 the Lakes, had hurt the sale of your work, and that you rather complained of it. 

 He did not say that you complained of me, and I assure you, you had no reason to 

 do so ; for I have no pecuniary interest whatsoever in Mr. Hudson's Guide. I have 

 told my tale fairly in my letters. Before I ever saw your face (which was in the 

 summer of 1S23), I had promised Mr. Wordsworth, when he published a new 

 edition of his Essay on the Lake Scenery (I do not remember its title), to give him 

 a sketch of the Geology of the Country. He asked me to do so (I think in 1822 

 and again in June, 1823), and I said, '•! have yet to learn the Geology of your 

 country ; but by the time you bring out a new edition, I hope to know enough for 

 the kind of sketch you ask for. " Thus I gave my word to him, more than once. 

 My promise was not claimed for twenty years ; and it was claimed by Mr. Words- 

 worth in a letter to me at Cambridge ; and when I sent down the letters to Mr. 

 Danby of Kendal, who undertook to see them thro' the press, I did not know what 

 was the exact nature of Mr. Hudson's work. I thought it was to be little more 

 than a reprint of Mr. Wordsworth's former little book, with a few notes and 

 additions. If I have hurt the sale of your work, I am truly sorry for it ; for I 

 think it one of the very best guides that ever was written, and I always recommend 

 it. But I have also hurt the sale of Panoramic Views by Mr. Westall, my brother- 

 in-law. He tells me that I have almost destroyed the sale of views of which he 

 before had made a considerable profit. If so, there was no help for it. I was 

 bound by my promise, and must have performed it, tho' I had foreseen the conse-
