Deep Mining.

Prof DANIELS, State Geologist of VII
coasiO. is publishing IN the Madison Jour
nal series Of articles on the subject Of deep
mining anI the resources Of the mining
region, which will he read with attention

port OF the deep mining theory, he says:

Let any one enquire of those miners who
are most intelligent, experienced AMI best

Those whG oppose this doctrine will gen

only the irregular aud intelmitted digging

parts of our lead district. but which bears
about the same relation to mining proper

The opinions are simply gucsses, having
precisely the same value as those of men
who have never seen the mines at all.

Of opinion is overwhelmingly in favor OF
the PROPOSITION s'that the veins extend in

In regard to the failures in deep mining,
remark that they prove nothing whatev-

have been induced by variety Of causes,
such as bad management, high prices O
