| 8-9. Each book of field notes has a small-scale index diagram of the lines included, for which there is a form on back of the cover. It is often necessary, however, to construct an additional special diagram to suit the work. For this a sheet of regulation field-note paper, or a sheet of the same size, is employed, and a scale adopted that is suited to the available space. It is usually preferable to orient the diagram with north to the top of the page, though sometimes the outline of the work is such that it is better to orient the diagram with north to the left-hand or binding edge. The diagram should show all of the lines surveyed with the page number on which the record of each begins. Meanders and other irregular lines should be drawn and indexed. The added index sheet is inserted in the book on the inside of the front cover, to appear on the right-hand side, without page number. Field notes will not be written on the index sheet. |
