Geological Map of the Lakes (?)

---

	map type:- Otley 1820s map
	Geological Map of the Lakes? perhaps coloured on his own topographical map by Jonathan Otley, Keswick, Cumberland, about 1828? Jonathan Otley:- 'When my map first came out in 1818, Mr. Farey was at the Black Lead Mine; he felt great interest in it, and got favourable notices inserted in the Monthly Magazine, When here again, about 10 years later, he pressed me very much to colour it as a geological map, and so did others. I tried a few, but could not entirely satisfy myself, and did not find it likely to be profitable. I sold to Dr. Buckland and Mr. Greenough each one, with a sheet taken out of the Guide, at 5s. each. This was the most I recollect making out of it.' In a letter 1847, Adam Sedgwick wrote:- '... Do you wish to publish a geological map of your country, on the scale of your Lake Map? If so, I would most willingly help you to the best of my power; and you might use my name in any way you thought fit.'
