To the President and Members of the Geological Society of Pa, 



Gentlemen — Having obtained your permission to 

 make a separate report upon the Rappahannock, or 

 Smith's gold mine, by way of supplement to the joint 

 report presented by Mr. Del Rio and myself on the 4th 

 inst., I beg to say, that for the purpose of more fully in-

 we had previously made, I was induced to examine the 

 land again, which has enabled me to fully confirm and 

 corroborate all that we advanced in that previous re- 

 port. 



That report, however, refers only to the central, or 

 principal vein, marked AA in the plan, and to another 

 small vein, BB, colored yellow, to the northwest of the 

 central vein, and believed to be parallel to it, but of 

 which we stated the direction towards the south-west, 

 could not be very distinctly determined on account of 

 the land being thickly covered with wood. 



From the form of the hills, the stony indications on 

 the surface, and a careful examination of the course of 

 the rivulet and ditch between No. 4 and C, I was in- 

 duced to suspect other metallic veins to the south-east 

 of the central ore, and after a careful search the vein 

 DC was found, developing itself finely at the point C, 

 though nearly hidden by the bushes. It is situated at 

 the distance of ninety-two yards to the south east of the 

 central vein, and though short, has a promising appear- 

 ance, and its ores on trial appeared good, but they were
