The Coals Of South Wales PDF Download

Excerpt from The Coals of South Wales: With Special Reference to the Origin and Distribution of Anthracite Preparations for this Memoir on the Coals of South Wales were commenced in 1901, when Sir Archibald Geikie was Director-General of the Geological Survey, and the collection of material has proceeded since that date, as circumstances allowed. Though obviously incomplete, in the sense that analyses might be multiplied indefinitely, the work had so far progressed in 1907 as to lead to a more or less definite opinion as to the relative distribution of anthracitic and bituminous coals, and as to the origin of the difference between them. The time appeared, therefore, to have arrived for publication of the results, though admittedly a larger number of analyses would add precision to the generalisations, and illustrate more fully certain seams and certain parts of the coalfield. Necessarily there was much doubt at its inception what form the investigation should take. That each seam should be examined separately, and its modifications traced step by step from the bituminous into the anthracitic region, was clear. It was desirable also that all analyses should be made on a uniform system. For various reasons, explained in the following pages, it was impossible to follow fully so ideal a scheme. Samples of coal were not always procurable from the desired seam or locality, while a large number of analyses, the accuracy of which there was no reason to doubt, would have been inadmissible. Eventually it was decided that while special attention was being devoted to certain seams, opportunities ought not to be lost of getting specimens of others which happened to be accessible. Difficulty arose also from the natural reluctance of the colliery proprietors to consent to the publication of coal-analyses over which they had had no control. This was overcome by the assistance kindly rendered by the South Wales Institute of Engineers. Not only was an arrangement made with the proprietors under which specimens could be collected and analyses published, but through Mr. Jones Price, Secretary to the Institute, we were kept informed where specimens could be procured.
