At Leeswood Green, a fault fortunately brings the Cannel up to 
the level of the Main-coal. The Cannel is variable in quality, 
and to the South, in the Denbighshire Coal-field (separated by a 
great fault from the Flintshire area), the Cannel is represented by 
the ‘Lower Yard Coal,’ the good house-coal of Ruabon. Much 
interesting information is given in this paper, and it contains a well- 
merited compliment to the Geological Surveyors for their laborious 
and conscientious field-work, so little thought of or understood except 
by those who have to follow them, and adopt their useful results. 
Mr. Jones, Secretary of the Society, read a paper (at the Cannock 
Chase Field-meeting), on Organization in Field-club work, well 
worth attention, particularly recommending continuous scientific 
work, in special directions, for the Botanists, Chemists, Geologists, 
and Antiquaries of particular districts, bringing their results to 
the natural centres, where the Clubs exist, and the preparation of 
Scientific Guide-books, as in the Malvern Club, or the recording of 
information as in the Institute of Mining Engineers for the Northern 
Coal-fields, and in the Dudley Society for South Staffordshire. 
Mr. Rupert Kettle’s paper on the working of the Ten-yard Coal, 
printed separately, is appended to this No. of the Transactions, but 
the discussions after the reading of the paper are fully given in 
the No. itself. A commission was appointed to undertake the neces- 
sary experiments and collect evidence. The paper is briefly noticed 
in the GroLoaicaL Magazine, No. 5.

[PP this we find an enquiry (in Mr. H. O’Hara’s paper), into the 
character and extent of the Irish coal-fields, peat-bogs, and 
supply of fuel, which ought, it seems, to be increased by plantations 
of timber-trees, by enlarged workings of the collieries, and by the 
adoption of improved methods in draining the peat-bogs, and in 
digging, drying, and compressing the peat. Detailed accounts of 
the Irish peat-bogs and coal-fields are to be found in this paper, 
together with a map of the former, and a map and sections of the 
latter.
