WAVERLY GROUP. lOI 



group can be reached by deep borings ; in many localities a brine 

 of equal strength with the best brines of Saginaw district has been 

 found, without an attempt made to utilize it. 



The manufacture of an article as cheap as salt depends not only 

 upon the supply of good brine, but upon the expense of convert- 

 ing the brine into the merchantable article. In this respect, 

 only large saw-mill establishments, with their immense mass of 

 waste fuel, can enter into successful competition with the Eastern 

 and Canadian salt works, with a fair chance of profit. In all other 

 cases, its manufacture would hardly more than pay the expense of 

 the fuel used for evaporation of the brine. 



An exposition of the salt-manufacturing process, of chemical 

 analyses of the salt brines of different localities, statistical records 

 of the salt production in Michigan, etc., are given in an appendix 

 elaborated by the State salt inspector. Dr. Garrigues, who kindly 

 offered his help, and, being in the possession of all the facts relating 

 to the matter, was far better qualified to make this part of the re- 

 port than I could be, however well disposed.
