sufficiently rich to pay for working. So far as I can jud 
5% of tinstone isa payable return, and in some cases even less 1S 
worked, 2 or 3 per cent. paying for crushing. 
The lode has been traced for a great distance along the surface, 
and a shaft about 60 feet deep sunk from the adit level, carrying 
the lode down with it. The country in which the lode occurs 
consists of a porphyritic granite, which is decomposing rapidly on 
the surface, but there is not much white mica in the rock, and, 
although it is found in the lode, it does not appear to be of frequent 
erse granite, and it is probable that this chlorite is a product of 
decomposition of the rocks which were shattered by the movement 
which first opened the reefs. 
The following sketches illustrate some of the points of interest 
in connection with Butler's lode. he positions of the rich parts
