WATER CONTENT. 



The matter that is carried in all natural waters in varying quantities and proportions 

 consists of suspended matter, both dead and living, minerals and other ordinarily soUd 

 substances in solution, and dissolved gases. All of these classes of substances are utilized 

 by fresh-water mussels in one way or another, and the quantity of any of them in the 

 water has a direct bearing upon the suitability of waters for mussels.
