EARTH'S DIAMONDS; OR COAL, ITS FORMATION AND VALUE. WITH A Plea for the Miner. BY HENRY H. BOURN, AUTHOR OF "BLACK DIAMONDS," "CHRIST IN THE PENTATEUCH," "GLEANINGS S. W. PARTRIDGE & CO., 9 PATERNOSTER ROW. PREFACE. ANY who read the following pages will be surprised MAN to find that the coal production of this country has attained to such enormous proportions as indicated; and by the figures and facts supplied will understand to some extent our indebtedness as a nation to God for the treasures we possess in our seams of coal. I am pleased to know that my former efforts to awaken an interest in the minds of others on behalf of our miners have not been altogether in vain; and I sincerely hope that the information given at this time respecting the dangers by which they are surrounded while following their employment may secure them a large measure of consideration and sympathy. The attention of colliery proprietors, mining engineers, and managers is especially invited to the chapters on "CoalDust an Element of Danger in Coal-Mines," and "The Dangers connected with the Use of Gunpowder and other Explosives in Fiery Mines." It is hoped that the subjects Idealt with will receive that consideration which their importance justly demands. |
