112 PEECIOUS METAXS IIv" THE WEST OF ENGLAND. 



Mr. Hutcheson, in the raised beaclies and sands of Godrevy 

 Island. 



Mr. F. J. Stephens, in various places between Falmouth and 

 the Lizard ; also in the raised beaches of Falmouth and 

 Grerraus bays. 



The late Sir Clement Le Neve Foster, while still resident 

 in Cornwall, made a washing test at Mudian Vean in 

 Manaccan, in company with Mr Henry Francis, and found a 

 few spangles of gold in the black titaniferous river sand there. 



The occurrences of gold in the West of England are not 

 confined to quartz, iron pyrites, and gozzan ; distinct traces are 

 always to be found in the copper ores, and often in the ores of 

 tin, lead and zinc. Capt. Hambly believes also that it exists in 

 the well-known Ladock sandstones and conglomerates, but this 

 suggestion needs confirmation.^^ 



Silver. 

 Silver is much more abundant than gold in the West of 

 England, for, not only have considerable pockets of true silver 

 ores been often found, but it occurs in paying quantities in 

 nearly all the lead-ores, in many of the ores of copper and 

 zinc, and probably in some of the tin ores ; as also in most of the 

 gozzans. Neither native silver nor true silver ores have been 

 found in the tin-stream works, but many rich pockets of such ore, 

 often worth thousands of pounds, have been found in cross- 

 courses near their intersections of right-running veins and vice 

 versa, especially in the Hayle, Gwinear, Liskeard, and Calstock 

 districts, as also at several places in Devon. In Cornwall, a 

 piece of native silver, " as big as a walnut," was found at Wheal 

 Cock in St. Just in the year 1753.^- "Fibrous native silver" 

 associated with horn- silver was found at a mine in Perranzabuloe, 

 hence named Wheal Mexico, in the year 1788. In all about 

 £2,000 worth was raised from here, in and above the adit.^ 



31. " It is precisely into the valleys traversing the districts named (by DelaBeche, 

 viz., St. Ewe, Creed. St. Stephens, St. Mewan, Kenvvyn and Ladock) that the products 

 of the decomposition of these rocks (the conglomerates) would naturallj' fall. I have 

 here a gold ring made of metal recently taken from the sand at Portreath beach, 

 which for a depth of 8 to lo feet has been stripped and washed by my friend, Capt. 

 Evans." (Hambly, Report R.C.P,, 1887, p. gg).
