The district court has not admiralty jurisdiction of a libel
in rem against a vessel for damages caused by its
colliding with a spur dike, a structure mainly of wood, driven into
the bed and extending out from the bank of a navigable river, the
purpose of which is to improve the channel in aid of navigation by
producing shore deposits through a slackening of water flow. P.
266 U. S.
434.
Appeal from a decree of the district court in admiralty which
dismissed a libel for want of jurisdiction.
Page 266 U. S. 434
MR. JUSTICE McREYNOLDS delivered the opinion of the Court.
The United States libeled the steamship
Panoil and
asked a decree for $2,000 because of damage inflicted upon spur
dike No. 5, a structure extending into the Mississippi River. Upon
exception duly taken, the district court correctly concluded that
it lacked jurisdiction of the matter, and dismissed the libel.
In order to deflect the current and cause it to deepen the
channel at the mouth of the river, the United States built
submerged dikes and sills, composed of willow mattresses weighted
down with stone; also several spurs. Spur dike No. 5, located near
the "Head of the Passes," consists of a cribwork of round piles,
hewn walings, and
Page 266 U. S. 435
sawn cross-braces, all securely bolted together, with a curtain
of round piles bolted against the upstream face. It is driven into
the bed of the river, and extends out about 700 feet from the east
bank, approximately at right angles to the channel. Its special
purpose is to slacken the current, induce deposits of sediment, and
eventually built out the shore, and in this way to improve the
channel and aid navigation. Proceeding in a thick fog, the
Panoil struck this dike, shoved 30 feet of the channel end
upstream, and so damaged it as to require rebuilding at an expense
of $2,000.
Appellants maintain that, as the dike is an aid to navigation,
the court below had jurisdiction of the alleged tort within the
doctrine of
The Blackheath, 195 U.
S. 361, and
The Raithmoor, 241 U.
S. 166. We think the principle of those cases does not
go so far. The dike constitutes an extension of the shore, and must
be regarded as land. The mere fact that its presence may affect the
flow of the water, and thereby ultimately facilitate navigation, is
not enough to bring the injury within the admiralty jurisdiction.
