226 REPORT—1904. 
A number of boreholes have been put down in the neighbourhood of 
Turn Dub (see previous reports), the result being that a thickness of from 
7 to 8 feet of boulder clay has been proved below the present river-bed. 
This, it is considered, is sufficient to account for the passage of the 
underground water below the surface stream. 
The boreholes are still in progress, and the Committee therefore 
seek reappointment, with permission to retain the unexpended balance. 
A full account of the work of the Committee will be published in the 
Proceedings of the Yorkshire Geological and Polytechnic Society. 
Life-zones in the British Carboniferous Rocks.—Report of the Com-

A. H. Foorp, Mr. H. Fox, Professor E. J. Garwoop, Dr. G. J.

TuE Secretary once again regrets that he has received no reports from the 
large majority of the members of the Committee. 
Work has been done by Mr. J. T. Stobbs in three districts. He has 
again generously given his time, and therefore the grant is only debited 
with travelling and out-of-pocket expenses. 
It was found impossible owing to mining difficulties to work the 
marine band which occurs in the North Staffordshire Coalfield below the 
Gin Mine coal. But for the sum of a few shillings a trench was dug across 
the strike and the beds were exposed in succession. The marine band 
was exposed and some few fossils were collected, but the bed was much 
weathered by proximity to the surface, and it was found inadvisable on 
this account to make any prolonged search for fossils. However, the 
position of the marine band with regard to the Gin Mine coal, a subject 
on which in the course of years a curious error had arisen, was definitely 
settled. Sections and a list of fossils obtained are given in Mr. Stobbs’s 
report. 
‘ As excavations for waterworks were being carried on in the Valley 
of the Derwent Mr. Stobbs went there to examine the cuttings in the 
Pendleside Series, the upper portion of which was then exposed. A 
detailed report follows. 
It was also thought good to examine the northern boundary of the 
South Wales Coalfield, and as far as possible to collect from the small 
coal workings, confined to single seams. In the recent resurvey of the 
South Wales Coalfield paleontology does not seem to have had the 
attention paid to it which it deserves. The grant therefore has only been 
partially used, and the Committee ask that the balance may be retained 
for future work. 
Personally, while collecting in the Carboniferous district of the 
Midlands, the Secretary has been examining the Devonian Carboniferous 
succession in the south-west of Ireland and North Devon, the results of 
which are expressed in a paper published in the ‘Geological Magazine’ for 
August 1904. 
It is well known that the Carboniferous Limestone in South-west
