me how in view Of them any doubt could

Tor example, speaking Of the Missouri
mines the article says: ' The most pro

IN The south east part Of the state The
geological formation in which they are

Which is there unproductiye, Is, what
the writer surely was not justified in say

We know here that at Blue River
Dizsings, ii this county, it has been for
years wrought productivity. And By
what force Of logic the conclusion is de
rived.from the premises it is not easy TO
see. On the other hand We have a ready
answer. in the fact, that the lower mar

or two, has never been tested Cnnro-
