A ship-yard plundered.
--The ship-yard on the south side of James river, opposite Rocketts, was robbed on Tuesday night of property amounting in value to one thousand dollars, as follows: Fourteen kegs of nails, four kegs of composition spikes, a lot of copper bars and five jack-screws. The safety valves and oil cups were also taken from a steam engine near the place. A citizen engaged there thinks there must have been at least forty men engaged in the robbery. On the north side of the river, where the articles were carried, the marks of feet were plainly traced.
