reliable but the velocity immediately south of the bed was 
0.5 of a mile per hour. 
The currents of the Nanticoke channel and over the adja- 
cent beds, set to the northward and eastward on the flood, 
following the bend of the channel, with a maximum velocity 
of 0.6 of a mile per hour. 
The ebb over the major portion of the Middle Ground sets 
to the southward, with a velocity of 0.3 to 0.4 of a mile per 
hour on the first quarter, until it meets the current of the Wi- 
comico, when it turns to the westward. 
A strong current sets in and out of Rock Creek ; over the 
Drumming Shoal and Cedar Rocks, the current sets H. H.E. 
on the flood, with a velocity of 0.4 of a mile per hour and 
S. S.W. on the ebb tide, with a velocity of 0.6 of a mile per 
hour. 
Over the beds south of the Shark’s Fin and Cedar Rock, 
and north of Piney Island Bar and Hedges Straits, the gen- 
eral set of the flood is to the northward, with an inclination 
towards Holland’s Straits, when about Turtle Egg Island, and 
tending to the northward and westward off the Little Thor- 
oughfare. The general set of the ebb wdiile in the channel is 
to the southward, but on the Turtle Egg Island, Mud and 
Muscle Hole Rocks the set is to the southward and eastward. 
The strength of these and all currents in the Sound is much 
influenced by the winds that have prevailed during the im- 
mediately preceding days and which it w r as impossible to 
eliminate in the space of time covered by this investigation. 
Over the western beds, above Hedges Straits, the maximum 
observed velocity of the flood was 0.8 of a mile per hour, and 
a mean of all the velocities of the flood current was 0.4 of a 
mile per hour. 
The maximum observed velocity of the ebb current was 1.0 
mile per hour, and the mean of all velocities of the ebb was 
0.3 of a mile per hour. 
Over the Chain Shoal the maximum velocity of the flood 
was 0.37, and the mean velocity was 0.3 of a mile per hour. 
The maximum velocity of the ebb was 1.0 mile and the 
mean velocity 0.5 of a mile per hour.
