    Abstract

    THIS volume is the third of the series of “Practical Coal Production” and may be looked upon as a continuation of the two previous ones, which have already been discussed in these columns. The present volume is no advance on its predecessors, showing quite as strongly as they do the defects previously indicated, and being perhaps even more ‘scrappy’ than either of the others. It contains three chapters, on mine transportation, hoisting and hoisting equipment, and coal preparation respectively. The first part consists of a miscellaneous collection of information concerning animal and locomotive transport underground; perhaps the best point about this section is the considerable attention paid to underground track work, the importance of which is just beginning to be recognised by colliery managers. Chapter ii. is almost wholly taken up by calculations, such important matters as the construction and design of cages and headgears not being even mentioned. Having regard to the recent developments in American coal mining, one would have expected to have found some information, at any rate, as to the employment of skips instead of cages, but this again has been entirely neglected. The third chapter is taken up mainly with coal conveying and screening. The author is aware of coal washing, but he dismisses it in a few lines, as though it were not in fact the most important part of coal preparation at the present day.
