As it is obvious the entire sketch must be made from theone point ofobservation, A, hence the term, place sketch. Itis also obvious that the entire sketch must be made fromobservation. Sketches of this class are hastily made on theback of the message forms furnished organizations in the field.

As to the contour lines, assume as the datum plane the down-stream end of the largest stream, and, for convenience, callthis elevation zero, or assume some elevation for your lowestcontour as 100 feet, as is the case in Fig. 28.
