Introduction. 

 The object of this research is to determine the normal 

 chlorine content of spring and brook waters of Nova 

 Scotia. By normal chlorine content is meant the amount 

 of chlorine, chiefly as sodium chloride, found in unpolluted 

 waters that maj" be considered to have been taken up bj^ 

 the water from the soil of the surrounding area. This 

 chlorine content is estimated along certain hues crossing 

 the region, and points having the same content are con- 

 nected by lines on a map of the region. These latter lines 

 are therefore Lsochlor Lines, or shortly Isochlors, (just as 

 we have isobars, isotherms, etc.). 



Sources or Chlorine. 

 There are probably three main sources from which this 

 chlorine is derived — ^chlorine mineral deposits, the sea and 

 sewage. According to the "Report of the Salt Deposits 

 of Canada and the Salt Industry", prepared by Heber Cole, 

 B. Sc. (No. 325 of the publications of the Departments of 

 Mines of Canada), there are nine separate salt spring regions 

 in the Province of Nova Scotia. Of these four are in Cape
