near ?in thick and 2 wide long, and are more or less round,
The quartz pebbles range up to 3 or 4 inches but more often are
under 1/2 inch. An out cliff showing a limestone conglomerate.
The sand and quartz pebbles may have been derived from the
Laugon conglomerate and conglomerates. The grue shows some current
action in the flat arrangement of the grains and in the bedding
planes.
The thick conglomerate or ators like this Resting upon the
Knock Shales is a grue about 10 feet thick in which the boulders
are emplaced because of the darker muddy-sandy parts. The
pieces are 9/10 lie. of minor lines, the rest being a chlorite green
sandstone, and some are quartz grits (one piece may be pre-Cambrian).
As a rule the blocks are flat, usually 3 to 8 inches thick with
single ones up to 14 inches more, and in depth usually under 18
inches. As a rule they lie flat or at slight angles but once
occasionally one of the blocks itself is a limestone conglomerate.
In a while one may be set horizontal. The grue does not show
any dropping into and destruction of the Knock Shales beneath it;
Then follows a middle thick creamy white limestone
worked about 12 feet thick
except all uniform stone can occur at rare intervals for
