A profile of the soundings is also included showing the depths of these 

 souiidings except those along the contact line, and indicated from vk^est to east 

 by consecutive numbers and each line is indicated alphabetically from north 

 to south. 



An imaginary base line was run from point number 3 on the traverse south 

 astronomically and the numbers are indicated by a plus sign if to the east of 

 that line and by a minus sign if to the west. 



Field notes are included showing the length and azimuth of each course, the 

 stations being numbered consecutively from 1 up. Shore offsets are shown together

We trust all returns may be found in order.

 Survey of Lower and Middle Shebandowan Lakes. 



Port Arthur, March 22nd, 1919. 



Sir, — I beg to report as follows on the survey of Lower and Middle She- 

 bandowan Lake undertaken in accordance with your instructions of September, 

 1917, for the purpose of ascertaining the area of the lake, the contour of the 

 shore line and islands therein. 



As previously reported the very early advent of winter and unusually stormy 

 and wet weather rendered it impossible for me to continue the field work without 

 serious loss and impairment of efficiency. Micrometer work was consequently 

 abandoned, as approved by your Department, and survey resumed with stadia 

 measurements in the following spring on the ice. 



As you will notice by the field notes every detail in the shore line has been 

 carefully outlined — the number of measurements being in excess of the actual 

 requirement of the instructions. The chief difficulty lay in tracing out the lines 

 and posts of the old Mining Location Surveys, an especially difficult matter when 

 the snow is deep. Many could not be found. Their proper position on the map 

 can, however, be readily approximated by the interaccordance of the two outline 

 surveys. Hereafter an explorer or prospector will find no trouble, by means of 

 this map, in locating his find so that the area intended will be distinctly evident 

 and the work of the Department likewise greatly lightened. Delay in making 

 out the more than usually intricate set of field notes and plan occurred by my
