THE MAITLAND MINES.

nearly East and West, as the metaliferous lime- 
stone, in which the ore is found, can be traced 
to a considerable distance. 
A little of the copper has been analyzed at 
Cape Town, which gives upwards of thirty per 
cent, of copper, and a little arsenic; but the 
quantity was small, and cannot therefore be 
taken for a just estimate. Twenty tons of lead 
and copper ore have been sent to England to 
be analyzed. There are also several other me- 
tals, which have not been analyzed, but they 
are not yet found in sufficient quantity to be- 
come a special object of working."* 
* The Author, whilst at Port Elizabeth in 1854, personally visited 
these Maitland mines, and can accredit the truth of the above state- 
ments. That ore, to a very large extent, exists there there can be 
little doubt : if it lies too deep, to pay for excavating it, is another 
question. Not professing, however, any accurate knowledge of such 
matters, he has pleasure in inserting the opinion respecting these mines 
of a scientific person fully competent to judge — It is as follows : — 
" The lead ore, in the Maitland mines, is in the form of a sulphuret 
disseminated, in greater or less manes, through a crystallized carbo- 
nate of lime, in a layer parallel to the stratification of its matrix, 
which is a semi-crystalline limestone, lying conformably on the quart- 
zite rock of the country, at an angle (I believe) of about 65°. The 
Galena (Sulphuret of lead) is found, crossing out on the top of the 
hill which faces the lodge, and also on the eastern extremity of the 
same. It was stated, that, on the top of this hill, it was found, when 
examined, to become richer the deeper the exploration was carried. 
u From this circumstance, (supposing it to be correct) one would be 
led to hope that the adit, facing the lodge, would prove highly produc- 
tive when the lead-bearing-spar was reached. Although the fact, that 
the same layer, examined on the Eastern end of the hill above-men- 
tioned (if it really was the same, a fact which I think of the 
highest importance to be determined) did not prove rich in that situa- 
tion, would not lead to so favourable an augry.
