section comprising among other elements the following :

The identification of the limestones is not made positive, but no 
good ground for objection to it is recognized. The Clay Vein coal is a 
few feet below railroad grade. 
At the works of the Great Western Fire-clay Company, half-way 
between Elliottsville and Toronto, the interval between the Clay Vein 
and Roger coal, both of which are worked, is 85 feet. The Clay Vein 
has fallen here to 40 feet below railroad grade.
