As the lead-bearing beds and the coralline beds were known to be palseontologically entirely distinct formations or groups of strata, so that the two must of necessity be absolutely distinguished from each other ; as the former were not the only lead-bearing, nor the latter the only coralline beds of the region, and as neither of them was the uppermost magnesian bed,...

It appears, also, from descriptions given me by intelligent miners who had worked at these diggings, that the opening-like character of the rock only extended for a short distance into the bluff, and that, on following the deposits beyond the point to which atmospheric agencies have had an opportunity of reaching, the strata became hard beyond all hope of profitable working. There can be no...

The last-named diggings are thus described by me in the Iowa Report: " Along the face of the bluff, in which a thickness of 120 to 150 feet of the Lower Magnesian limestone is exposed, a number of drifts have been extended into the rock a little below its juncture with the sandstone, and considerable galena has been taken out. The limestone at this point is brecciated in its structure, appearing as if it had...
