LANDS AND SURVEYS 



to plot each tree in the note-book, a table may be prepared 

 with the following columns. 



FIG. 6. 



The notes are kept in a cross-section book about 6f 

 by 8| inches, ruled in blue lines, ten to the inch. In work 

 of this kind it is especially important that the date should 

 be entered on each page. 



A map is then prepared on a suitable scale, depending 

 on the amount of detail to be plotted. The following 

 scales are used; 1"=30', 1"=40', 1" =50' and 1" = 100'. 

 This map is traced and the tracing forwarded to the land- 

 scape architect. 



For Large Reservations. The previous method should 

 be used if possible. Since, however, no grading is usually 

 contemplated except for wood roads, etc., and since it is 

 often impossible to run straight lines, the method of survey 

 by random lines, as nearly straight as possible, is adopted. 

 Side shots are taken by angle and stadia. This method is 

 not recommended when trees and other details must be 

 located. 



For Parkways. The method here to be followed is 

 that of carefully running a transit line through the middle 

 of the ribbon-like area, placing stakes every hundred feet.
