BULLETIN OF THE UNITED STATES FISH COMMISSION. 
The specific gravity at the mouth of Battery Creek at half ebb was 1.0228 surface 
and 1.0230 bottom; just above the junction of Jericho and Battery creeks, early flood, 
1.0223, surface and bottom ; abreast the phosphate works, one-fourth flood, 1.0222, 
surface and bottom. The total area of the creeks is about 512 acres; area of natural 
oyster beds, about 9 acres. 
Brickyard and Albergottie creeks. — The former of these creeks is but a continua- 
tion of Beaufort River and connects it at its northern extremity with the Coosaw River. 
It is about 4 miles long and has an average width of 150 yards. The bottom is 
generally hard and sticky, and underlaid in places by phosphate rock. The specific 
gravity at the upper mouth, on the early flood, was 1.0215 surface and 1.0213. bottom; 
and at the lower mouth or junction with Albergottie Creek, 1.0226 surface and 1.0227 
bottom. No oysters were observed in the Albergottie, its bottom and sides consisting 
of very soft mud. The total area of creeks is 560 acres; area of natural oyster beds, 
2.1 acres. 
Station Greek , Story and Harbor Rivers. — The territory south of St. Helena Island, 
between Trenchard Inlet and St. Helena Sound, was not examined, but we know that 
the usual conditions of salt-water circulation exist in this system, and the natural 
oyster beds were not located. From the best information that could be obtained it 
is safe to say that ledges of raccoon oysters occur along the shores which will not 
average more than 10 feet in width. The characteristic soundings of the Coast Survey 
charts can be relied on to give an idea of the bottom. 
Coosaw River. — This large tributary of St. Helena Sound is but a continuation of 
Whale Branch and completes the northern circulation between Port Royal and St. 
Helena Sound. It is about 13 miles long with an average width of 1 mile. It flows 
in an easterly direction and empties into St. Helena Sound at the southeast point of 
Morgan Island. The bottom is generally hard, consisting mainly of phosphate rock, 
but constant changes are being made by the phosphate dredgers. The extensive pros- 
ecution of this great industry precludes the successful cultivation of oysters within 
this territory, even if the conditions were very favorable. The specific gravity near 
the mouth during the first of the flood was 1.0206 surface and 1.0207 bottom; off the 
mouth of Dale Creek, 1.209 surface and 1.0211 bottom ; and at the junction with Whale 
Branch, 1.0198 surface and 1.0202 bottom. Raccoon oysters are found along the shores 
but are of poor quality, there being many dead shells and a small proportion of live 
oysters. In the upper part, the water is tinged on the ebb tide by the swamp water 
coming through Whale Branch. The total area of the river is about 7,104 acres; area 
of natural oyster beds, about 19.6 acres. 
Parrott Greek is a short arm connecting Morgan and Coosaw livers and separating 
Morgan Island from Coosa Island. It is about 2 miles long and will average one- 
fourth mile in width. The bottom is generally hard and sticky, and the specific grav- 
ity at its mouth was 1.0209 surface and 1.0211 bottom. Phosphate rock underlies the 
bottom of this creek also. It is now being mined in a small way, and subject to exten- 
sive operations at any time under the phosphate laws of the State. The total area of 
the creek is 355 acres; area of natural oyster beds, 4.6 acres. 
Dales Creek also connects Morgan River near its head with Coosaw River and sepa- 
rates Coosa Island from Ladies Island. It is about 4 miles long and 150 yards wide. 
The bottom is generally hard and sticky and the depth ranges from 11 to 15 feet. 
This creek is also in the phosphate region, and the Farmer’s Phosphate Works are
