The flood current over Piney Island Bar sets N. N.'W., or 
about in general line with the sound at that point. Its ve- 
locity on the third quarter, during and after northerly breezes, 
was 0.1 of a mile an hour, and probably it is seldom less than 
that. 
The ebb current over the northern part of the bed sets 
S. S.E., but tends to the southward over the southern part. 
The maximum velocity of the ebb during and after north- 
erly breezes was 1.00 mile per hour, and the mean of all ob- 
servations, taken under similar circumstances, gives a velocity 
of 0.4 of a mile per hour. 
In the Manokin River the current follows the general trend 
of the channel, the flood setting to the northward until above 
Hazzard’s Point, and then to the northward and eastward. 
The ebb sets southwest, and, when it strikes the shoal ofl 
Piney Island, curves somewhat to the southward. 
The currents shown on the chart were measured during 
light or gentle northeasterly breezes. 
The maximum velocity of the flood was 0.4 of a mile per 
hour, and the mean of all the velocities of the flood 0.2 of a 
mile per hour. 
The maximum velocity of the ebb was 0.5 of a mile per 
hour, and the mean velocity 0.2 of a mile per hour. 
In the Big Annemessex River the current sets to the east- 
ward on the flood tide, and to the westward on the ebb, curv- 
ing to the southward on the latter as it approaches the mouth 
of the river. 
The maximum velocity of the flood current was 0.4, and 
the mean velocity 0.25 of a mile per hour. 
Of the ebb the maximum velocity was 0.5 and the mean 
velocity 0.33 of a mile per hour. The flood current sets over 
Harris Rock to the northward, with a maximum velocity of 
0.33, and a mean velocity of 0.2 of a mile per hour. The 
ebb being somewhat influenced by the current out of the An- 
nemessex and the sweep of the main current of the Sound 
sets to the southward and westward, with a mean velocity of 
0.2 of a mile per hour. The maximum velocity observed was 
but a slight increase of the mean.
