PREFACE.

THE Practical Miner's Guide, by J. Budge, was republished in the pages of the Mining Magazine during the year 1856, and from the favorable manner in which it was received, the present publisher has been induced to reproduce it with such additions and alterations as seemed requisite to make it still more useful. As now arranged, it will be found to be at once the most complete, reliable, and useful book, to the Practical Miner, in the English language. In making the additions, the best practical authorities have been consulted and referred to, and it would seem proper that they should be mentioned here. "Greenwell's Treatise on Mine Engineering," "Annales des Mines," "Handbuch de Bergbau und Huttenkund, by Carl Hartmann," "Ponson on Coal Mining," "Phillips, Blackwell, Mackworth, and Hopton on Ventilation," "Combe's Traite de l'Exploitation des Mines," "Herbert Mackworth on Artesian Wells," &c., &c.

The great advantage of the diffusion of information of a practical character, is in no branch of industry more clearly apparent than in that of Mining. Its object may be considered two-fold; the first being the instruction of those who are contemplating Mining as a profession, and also those who are at present placed in situations of responsibility, but who, in many instances, know very little of the first principles of subjects with which they ought to be thoroughly conversant.

Throughout this volume the benefit of the Practical Miner
