Excerpt from Mine Drainage: Being a Complete and Practical Treatise on Direct-Acting Underground Steam Pumping MachineryTo these younger products of the engineer's skill, the surface engine may relegate much of its work, or it may engage them as auxiliaries, for which their much greater lightness of structure, their ready portability, and the celerity with which they may be set to work, make them so well adapted.Many admirable papers on underground pumping engines have appeared in the journals and transactions of the engi neering societies from time to time, but in this scattered state they are obviously only accessible to a very limited number of persons. Moreover, the high price of some of the journals containing these papers, and the trouble and perhaps impossibility of bringing together such of these isolated papers as might be required, would prevent the general reader availing himself of them. Many of these papers are the production of promoters of the engines to which they refer.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
