composed of limestone, even on the top of hills 700 feet high. What 
is most remarkable, however, is that in some places there are valleys 
and plains not more than 400 feet above the sea without a particle 
of limestone-drift on them, while hills in their vicinity are covered 
with it.’ * 
In sinking the various pits in the Queen’s County Collieries, a 
Stratified Drift was found under some of this Boulder-clay. When 
the place was visited, none of these sections could be examined ; but 
fortunately a record of each was kept in the ‘bore-books’ that are 
in the possession of the different agents and proprietors. 
This paper will refer principally to the drift at the Newtown 
Colliery, as B. B. Edge, Esq., of Clonbrock House, has kindly given 
me valuable information and details of some of the sections there 
situated. 
Near the west of this colliery, a pit was opened through 55:92 feet 
of drift, the details of which are copied from Mr. Ahern’s ‘bore- 
book,’ now in the possession of Mr. Edge.

In a pit due east of Newtown Cross-roads, three feet of peat 
(‘ which, although saturated with water, would blaze like a candle 
when placed in the fire’) was found under the Boulder-drifé. Mr. 
Edge gives the following as the approximate thickness of the beds

Five hundred yards north of Newtown Cross-roads, peat was also 
found: here it was under about 54 feet of drift. Of this place Mr. 
Edge says, ‘Peat was found embedded in the shale which formed 
the roof of the coal. It was about 2°5 feet thick ; but very little
