the portion of this bay nearest to Jaeko Pass, the bottom is mostly 

 composed of soft mud with only a few small hard areas. Farther 

 to the eastward, and in the southern arm of the bay, there are 

 many old reefs covering a considerable portion of the bottom. 

 The salinity of the water in these bays averages about 1.0158, be- 

 ing influenced by the flow from Timbaliei- Bay, where the salin- 

 ity is always higher than in a corresponding part of Cat Island 

 Lake. The amount of oyster food in the water is always large 

 and the currents are unusually strong for such shallow bodies 

 of water. 



Lake Felicity, lying to the eastward of, and a little northerly 

 from, Lake Barre, is a body of water five or six miles long and 

 about two and one-half miles wide. It is connected with Lake 

 Barre through Bayou Casse-tete, Bayou Racoon, and, more in- 

 directly, through several bayous and lakes farther to the south- 

 east. 



Lake Chien, at the nortliwest corner of Lake Felicity, is a 

 broad arm of the latter lake some two miles in diameter. At its 

 eastern end Lake Felicity empties into Tirabalier Bay through a 

 good-sized bayou known as Grand Pass Felicity, or Felicity Pass. 

 The depth of the water in this lake varied from four to eignt 

 feet. The bottom is generally soft, very few firm areas being 

 found anywhere in the lake outside of the living or extinct reefs. 

 There are several living reefs covering a large area in this lake, 

 all of them being situated near the shores, none of them more 

 than one-half mile from the banks. There are a number of small 

 icefs in the west end of the lake near the entrance to Bayou 

 Casse-tete, and a couple of extinct ones near the entrance ta 

 Lake Chien. In Lake Chien there are two large areas where the 

 oysters occur in scattered bunches hardly constituting a well- 

 defined reef. On the north side of Lake Felicity there is a more 

 or less well-defined oyster-bearing area that extends along for 

 nearly three miles parallel to the shore line in from three to six 

 feet of water. Toward the west end of this area the oysters 

 occur in scattered bunches, and the barren spots are more ex- 

 tensive than those bearing oysters. Farther to the eastward 

 the oysters become thicker so that there is a well-defined reef. 

 On the south side of the lake there are oysters practically all of 

 the way from the entrance to Bayou Casse-tete to Grand Pass.
