Excerpt from Canal and River Engineering: Being the Article Inland Navigation It is proper in the outset to state, that it is not our inten tion to explain the nature or principles of the varied class of works which the engineer finds it necessary to adopt in carrying out such operations as those to which we have alluded. At the present time, when so much is written on all branches of engineering, such a course would be uncalled for, and would indeed extend the present treatise greatly beyond the limits to which it must necessarily be restricted. For information as to such details, we must therefore direct the reader to the different books to which we shall have to refer, as containing full information on the subjects of which they treat. Our aim is rather to present the reader with a general resume of the state of our knowledge respecting the practice of engineering, as applicable to ia land navigation in all its branches, and to confine such detailed remarks as we may have to offer to those parts of the subjects only which are not fully treated in works al ready published; and here we must express our regret, that although we have many treatises expounding the principles of engineering, nevertheless the engineers of the present day have given comparatively few accounts of the effects that have followed the application of these principles in particular cases. In drawing up the following pages, the writer has found great difficulty in obtaining authentic ih formation ou applied engineering; and this must be his excuse for having in some of the sections been obliged to apply, it may be thought too largely, to his own experience for illustrations of his subject.
