After learning how to make good observations the observer should place the utmost confidence in them, and never yield to the temptation of changing them because they disagree with some preceding observations. Such discrepancies are in general an indication... Manual of Topographic Methods - Seite 52von Henry Gannett - 1906 - 88 SeitenVollansicht - Über dieses Buch
