Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. In this book the author has attempted to record for the benefit of others something of the results of thirteen years of experience in the practice and teaching of topographical surveying and sketching. There is no short cut to excellence in topographical work. Good maps result from the patient and careful labor of men thoroughly instructed in the means and methods of topographical representation.
