CHAP. IV.] FALSE STATION 93 



Then from traverse table : 



C E = 105 feet in direction N. 61° W. from C. 

 , C F = 209 feet in direction N. 514° E. from C. 

 Bearing of D from A = N. 29° E. 

 Bearing of D from B = N. 38i° W. 

 From the above data plot the positions of C, E, D, F, on 



as large a scale as convenient (say 1 inch= 100 feet), 



as in Fig. 14. 

 Result (by protraction) : T> bears from C, N. 8° E. 285 feet.

SKETCH. 



A sketch taken from a station is made with the object of 

 more easily identifying details to which it is necessary to take 

 angles. By having a view of hills, islands, houses, trees, etc., 

 from two or three stations they can, if fairly placed in their 

 proper positions, be easily recognised in the different sketches 

 wlien plotting. No description in the angle book will do this 

 so well, unless, of course, there is something very remarkable 

 in the object, but even then the position of it as shown in the 

 sketch will assist materially to prevent mistakes, and a curt 

 description is also written against it on the sketch. 



Sketching to this extent is within anybody's reach. A 

 fairly correct outline is all that is absolutely necessary, and a 

 very little practice will enable the least likely draughtsman 

 to make a sufficient sketch for practical purposes.
