lie between <strong>the</strong> "No. 7" <strong>coal</strong> bed <strong>and</strong> <strong>the</strong><br />
Herrin limestone over wide areas in sou<strong>the</strong>rn<br />
Illinois. The Jamestown limestone,<br />
not over I feet thick <strong>and</strong> usually less, resembles<br />

limestone. The two limestones are sepa-<br />
