CHAPTER IV 



MAP MAKING 



Uses of a Map. When a survey of a farm or other tract 

 of land has been made, a map should be drawn to show the 

 location of the buildings, fences, lots, roads, and of the trees, 

 streams, and other physical features of the land. A map 

 enables the mind to grasp the facts in a way not possible 

 with the field notes alone. Although not generally practiced, 

 a good map of the farm can be used advantageously in 

 directing the work of the farm. This map should also serve 

 as the means of recording the location of drains and water 

 pipes placed beneath the surface of the ground. If the fields 

 are numbered and the map placed in the office or dining 

 room of the home, it may be used as a basis in planning each 

 day's work. The map will set also forth in a very forceful 

 way any inconvenience in the arrangement of the buildings 

 or fields. 



The Final Map. The final map is made from the data 

 recorded in the field book. As has been said, a sketch map 

 usually forms a very helpful part of the field notes. The 

 final map must be drawn carefully as well as accurately, 

 and should be made as durable as possible. 



Drawing Instruments. The equipment for making maps 

 may be quite extensive, yet the essential instruments are not 

 many in number nor are they expensive. A good outfit 

 includes the following: A drawing board of soft wood and 

 about 20 by 30 inches in size, a T square, a triangle, a scale 

 providing at least 10 and 50 divisions to the inch, a ruling 

 or right-line pen, a compass for drawing circles, a bottle of
