Several conclusions can be drawn from the examination of Table 

 1 and Figures 1 and 2. During the first half of February, fresh- 

 water conditions prevailed in the vicinity of Altamaha Sound and 

 Doboy Island. The water of this region contained up to 449.6 milli- 

 grams per liter of suspended matter; consequently, its transparency 

 was very low (0.2 feet, Altamaha Sound). Its reaction in Altamaha 

 Kiver and adjacent streams was acid (pH 5.8 to 6.1), probably be- 

 cause of the addition of water washed from the swamps, while the 

 w^ater in the sounds and river not affected by the flood remained alka- 

 line (pH 7.3 to 8.4). Flood waters did not extend to St. Andrews 

 Sound and the mouth of St. Marys River, where the salinity was 

 17.9 and 22.3, respectively. In March, the salinity of the water in 

 Altamaha Sound rose to 4.1 on the .surface and 11.9 at the bottom.
