EXPERIENCE has demonstrated, on more than one occasion, that knowledge of the technical details of Surveying is often deficient amongst junior practitioners, either because they have not had sufficient practice, or because they have not received from their seniors those friendly hints by which much of the knowledge acquired during many years of experience may often be imparted in a few words. This has led the Author of "Land and Marine Surveying" to treat very fully, in the first chapters, of a number of details, on the understanding of which, though very simple in themselves, a combined accuracy and rapidity of operation mainly depend: these have been explained almost in the colloquial language in which a surveyor would address his pupils and assistants in the field, and the more fully that the combination of accurate and quick work is indispensable to secure practice.
