Mr. William Phillips on the Veins of Cornwall. 159 



from its junction with the east and west vein, and then succeeded 

 40 fathoms of what the miner terms orey ground. 



It seems to be the opinion of a very intelHgent and experienced 

 miner, Captain John Davey, who was a captain in Herland mine, 

 and Is now the managing captain of Huel Alfred, that the contre of 

 the latter is a continuation of that of Herland. 



The east and west, or regular metalliferous vein averages about 

 2j feet in width, and runs 10 degrees south of east and north of 

 west : it underlies 2^ feet in a fiithom towards the north. The ore 

 was about 110 fathoms In length east of its junction with the 

 contre, but the east and west vein is poor every where when in 

 contact with it, except at the only place at which also the contre is 

 rich, viz. at about 117 fathoms from the surface. 



West of the contre the east and west vein Is lost for nearly 

 30 fathoms; and when discovered again, It varies from 18 Inches 

 to 4 feet In width and its load was found chiefly to consist of 

 fiucan with some blende. 



The ore of the contre is yellow and occasIonalFy compact, but It 

 Is for the most part approaching to black externally ; and where 

 richest, is loosely intermingled with small portions of quartz, blende, 

 and iron pyrites, which prevailed very much near the surface. 



The ore of the regular vein east of the junction with the contre 

 Is also yellow, and for the most part hard ; but It is occasionally 

 loose. 



The common effect of a cross or north and south vein is that It 

 passes through the east and west or metalliferous vein, and mostly 

 alters Its course, of which numerous instances are shewn on the ground 

 plan of Herland, Drannack and Prince George Mines. A cross vein 

 occurs in Huel Alfred ; Its effect on the east and west vein is not 

 yet known, but a rare exception to the general rule of north and
