Geological Address at Manchester, 415 



British Association, Professor Philips, who by his labours threw 

 much new light on the palaeontology of Devonshire, who, in the 

 Memoirs of the Survey, has contributed an admirable Monograph 

 on the Silurian and other rocks around the Malvern hills, and 

 who, by his lectures and writings, is now constantly advancing 

 geological science in the oldest of our British Universities. 



" There is yet one subject connected with the Geological Sur- 

 vey to which I must also call your attention — viz., the mineral 

 statistics of the United Kingdom, as compiled with great care and 

 ability by Mr. Robert Hunt, the Keeper of the Mining Records, 

 and published annually in the Memoirs of our establishment. 



" These returns made a deep impression on the statists of foreign 

 countries who were assembled last year in London at the Inter- 

 national Congress. The Government and members of the Legis- 

 lature are now regularly furnished with reliable information as to 

 our mineral produce, which, until very recently, was not obtain- 

 able. By the labours of Mr. Robert Hunt, in sedulously collecting 

 data from all quarters, we now become aware of the fact that we 

 are consuming and exporting about 80,000,000 of tons of coal 

 annually (a prodigious recent increase, and daily augmenting). 

 Of iron ore we raise and smelt upwards of 8,000,000 of tons, pro- 

 ducing 3,826,000 tons of pig iron. Of copper ore we raise from 

 our own mines 236,696 tons, which yield 15,968 tons of metallic 

 copper ; and from our native metallic minerals we obtain of tin 

 6,695 tons ; of lead, 63,525 tons; and of zinc, 4,35*7 tons. The 

 total annual value of our minerals and coals is estimated at 26,- 

 993,5 73Z., and that of the metals (the produce of the above mine- 

 rals) and coal at 37,121,318?. 



" When we turn from the consideration of the home survey to 

 that of the geological surveys in the numerous colonies of Great 

 Britain, I may well reflect with pleasure on the fact that nearly 

 all the leaders of the latter have been connected with, or have 

 gone out from, our home geological survey and the Government 

 School of Mines. 



" Such were the relations to us of Sir William Logan in Cana- 

 da, of Professor Oldham in India, with several of his assistants ; 

 of Selwyn in Victoria, of my young friend Gould in Tasmania, as 

 well as of Wall in Trinidad ; while Barret, in Jamaica, is a wor- 

 thy pupil of Professor Sedgwick. Passing over the many interest- 

 ing results which have arisen out of the examination of these
