The difficulty and the importance of keeping the Field-notes clearly and distinctly, increase with each newcombination of methods. For this reason, three different methodsof keeping the Field-notes of the same survey will now be given,(from Bourns Surveying), and a careful comparison by the stu-dent of the corresponding portions of each will be very profitableto him.
